OPINION
RUSHING, P. J. 
Defendant Cameron Lee Earle was charged in two separate cases with indecent exposure, a misdemeanor, and sexual assault, a felony. The charges arose from entirely distinct and dissimilar incidents with no apparent historical connection to one another. After first ordering the charges consolidated, the trial court denied a motion by defendant to sever them for trial.
At trial defendant tacitly conceded the indecent exposure charge, proof of which was strong. The underlying conduct occurred in broad daylight; the perpetrator's license number, which the victim recorded, belonged to a car then owned by defendant; and the victim positively identified defendant from a properly conducted photographic lineup.
The assault case was considerably weaker. The underlying incident occurred at night in a parked car illuminated only by overhead parking lot lights. The victim's description of her assailant and his vehicle did not match defendant or his vehicle. She characterized her assailant as looking Mexican, with light brown skin resembling her own; but defendant presents a distinctly pallid, European appearance in photographic exhibits, was described by a police booking officer as "white," and apparently looked European to the *379 victim of the indecent exposure, whose description to police resulted in a photographic lineup all but one of whose subjects has an unmistakably northern European appearance. The victim described her assailant as "skinny," but photographs of defendant suggest an athletic build. The victim failed to notice anything unusual about the assailant's forehead or ears, but the photographs depict a deeply furrowed brow and protruding, possibly damaged ears. The pictures show an unmistakably athletic bull neck that, like defendant's prominent ears and deeply furrowed brow, contrasts distinctly with the assailant's features in a police sketch.
The victim described the assailant's vehicle as a 1986 Ford Bronco, but the only other witness said it was a pickup. The victim seemed to confirm her own original perception shortly after the assault, when she reported a Ford Bronco to police as possibly the suspect's vehicle. But defendant did not drive a 1986 Bronco; he drove a 1981 Chevrolet Blazer. Furthermore, defendant was a world-class competitor in the sport of "submission grappling," but the victim of the assault managed to break the assailant's grasp, escape the vehicle in which he sought to subdue her, and flee the scene.
These and other facts, discussed in greater detail below, provided fertile ground for a reasonable doubt in jurors' minds that the victim had correctly identified defendant as her assailant. Given this background we conclude that the court committed reversible error by permitting the prosecution, through the expedient of a joint trial, to place the strongly incriminating evidence of the misdemeanor charge before the same jury that would have to decide the much more difficult felony assault chargea charge to which it was irrelevant, at least in the absence of foundational evidence that was not presented. This led to a grossly unfair trial in which the prosecutor explicitly urged the jury to convict defendant of the assault based upon his commission of the indecent exposure, which the prosecutor compared to DNA evidence and "modus operandi," and cited as proof that defendant was a "predator" and "scary guy." Indeed the prosecutor relied on a variety of spurious legal theories to place the indecent exposure before the jury, as evidence of the assault, as often and emphatically as possible. The indecent exposure thus played a central role, and quite possibly a decisive one, in securing a conviction on the assault charge. We have thus concluded that the trial court abused its discretion by denying the motion for separate trials, and that even if that ruling was within its discretion, the resulting trial was so grossly unfair as to deny defendant's right to due process of law. We will therefore reverse the assault conviction.


*380 BACKGROUND

A. The Indecent Exposure

Gina Doe[1] testified that around 4:00 in the afternoon of September 30, 2004, while walking into the San Jose mobilehome park where she lived, she noticed a white Ford sedan driving next to her with its windows down. The driver, whom she identified at trial as defendant, told her to "[c]ome here." On approaching the car, she saw that defendant was naked from the waist down and masturbating his erect penis. She fled in search of aid and managed to write down defendant's license number while he turned his car around. As she continued calling for assistance, he drove away.
Gina gave police the license number she had recorded. It was stipulated that this number was registered to a white Ford Probe owned by defendant. Gina subsequently viewed a photographic lineup in which she identified an October 2002 photo of defendant as the man who exposed himself to her. The defense offered no challenge to her testimony.

B. The Assault

Gloria Roe (see fn. 1, ante) testified through an interpreter that in late 2004 she was employed selling tamales from a table in a parking lot outside a San Jose market. On December 30 of that year, she arrived at the lot shortly after 5:00 a.m. to set up her table. At some point she decided to adjust the position of her car. As she entered it, with one leg still outside, a man appeared at the door. She asked him to help her. Instead of replying, he lifted and half-pushed, half-threw her into the front seat, where they began to struggle. He pulled her head back by the hair while she sat on the center divider holding the steering wheel to keep him from forcing her into a lying position.
She asked him if he wanted money. He said no, told her to stop struggling, and said that he had a gun and a knife.[2] He spoke to her in what Gloria, who *381 does not speak English, described as "kind of broken half Spanish." Her told her "to allow myselfallow myself to have it done . . . ." Instead she "kept struggling. I wasn't just going to let him do what he wanted." He seemed to become more aggressive and to be infuriated by her apron and "fairly tight pants . . . ." She lifted a leg and tried to push him out of the car. At some point she got him to stop pulling her hair, and was able to open the passenger door. She "pushed him as hard as [she] could and . . . shot out the door on the other side." She ran to a nearby bakery, where she enlisted the aid of one of its workers. She testified that the two of them ran back to the scene of the assault in time to see the assailant drive away.

C. Description of, and Opportunity to Observe, Assailant

Gloria testified that the sun had not yet risen when she was attacked, and there was no light on inside her car. However, she testified, the driver's door was open and she could see the assailant's face from the overhead parking lot lights. She insisted that she got a good look at his face from a distance of about six inches. Interviewed by Detective Jorge Gutierrez shortly after the attack, Gloria described her assailant as about five feet nine inches tall, and "thin." She said he was wearing a black jacket.[3] According to Detective Gutierrez, Gloria described her assailant as "a light-skinned Hispanic male . . . ." However Gloria herself testified not that his skin was "light," but that it was "light brown," "similar" to her own. She denied using the term "Hispanic" to police, but acknowledged telling them that her assailant looked "Mexican American." She testified that she called him "a Pocho," meaning, "someone who was born here and has Mexican parents." She considered him "Mexican-American as opposed to just Mexican," not because of his appearance but "because of the way he was speaking Spanish, that he didn't speak it well."
About a week after the assault Gloria described the assailant to a police artist. She told the artist the resulting sketch, which was introduced into evidence, resembled the assailant. Defense counsel in her summation described the sketch as "look[ing] similar to a photo that was taken of Mr. Earle in ... 2002." Absent from the sketch, however, were the receding hairline, deeply furrowed brow, heavy neck, and protruding ears depicted in photographs of defendant. The face in the sketch is also thinner and has a more angular chin than the squarish face shown in photographs of defendant.


*382 D. Assailant's Vehicle

After returning to the area of the assault in the company of the bakery employee, Gloria saw her assailant climb into a truck and drive away. She initially described the truck as "pass[ing] right in front of us," but on cross-examination said it passed "at a great distance." She told police it was a "1986 black Ford Bronco." However, the bakery employee testified that it was a dark "pickup truck."
Asked at trial whether she remembered "anything unusual" about the truck, Gloria testified, "We noticed that it did not have the back window." She did not know whether the window was broken out or rolled down, adding, "It was far away that I saw this." There is no evidence that she mentioned a missing window in her original statement to police; she apparently first mentioned it after seeing defendant's truck.
On January 5, 2005less than a week after the assault, and not far from its locationGloria saw a vehicle that she thought resembled the assailant's. It was a black Ford Bronco with a rolled up, intact rear window. She wrote down the license number and phoned Detective Gutierrez, telling him that she thought she had found the assailant's vehicle. She later learned that the vehicle she saw was not involved in the assault.
It was stipulated that "[f]rom December 30, 2004, through January 18, 2005," defendant owned "a black 1981 Chevy Blazer." It apparently had a cracked or missing rear window. At trial Gloria identified it from photographs as the truck she saw driving away from the scene of the assault. Up until she saw it, she had never described the assailant's vehicle to police as anything but a 1986 Ford Bronco. Asked to explain this discrepancy, she testified that she never meant the year as anything more than an estimate. She also testified, "I didn't get that close of a look to see the exact make of the car. And I don't really know the types of truck that well, but to me it looked like the type of carit looked to me like a Bronco. And then I found out later that it was actually a Chevy that looks like a Bronco."[4] A friend of hers in Mexico had a Bronco, and she herself had a sport utility vehicle, a 2003 GMC Envoy.


*383 E. Defendant's Identification and Arrest

In the early afternoon of January 18, 2005, Gloria drove her own truck to a carwash about 10 minutes from the location of the assault. While seated in a waiting area looking out through some windows, she saw "from afar" what she described as "the same truck and the same guy" who had attacked her. He was sitting in his truck in the parking lot of a nearby store, facing in her direction. She watched him for a couple of minutes, she testified, "to see if that was the person that had attacked [me]." She acknowledged that she could not see his eyes, height, weight, or whether he was Hispanic. Nor could she read the truck's license plate. Asked if she could tell at that distance whether it was a Blazer or a Bronco, she replied, "All I know is that it was the person who attacked me and it was the vehicle."
When she was "really sure . . . it was . . . him"still before she was close enough to read the license plateshe telephoned Detective Gutierrez and left him a message. She continued to watch the man in the truck for several minutes as he sat "looking all around, kind of like he was looking for someone." He then moved over to another parking space. "He just kept moving around from one parking space to another. He would be in one space for a few minutes and then would move to another space."
On the telephoned advice of her brother, she left the carwash to get the license number. She followed the truck on foot as it moved into another store's parking lot. When she saw it coming back towards her, she ducked into a store, writing down the license number as it passed. Her brother arrived and picked her up. They continued to watch the truck as it moved from parking space to parking space. At some point Gloria's own truck emerged from the carwash and the black truck left the area.[5] By now Gloria was in touch with the police, who told her to follow him. She and her brother complied.
The driver made no attempt to evade them, though they were directly behind him. After driving a few blocks he stopped, got out, and went into a house. Two or three minutes later, the police arrived and went to the door. Shortly thereafter they escorted defendant out of the house, exhibited him to Gloria, and asked if this was the man who had attacked her. At that moment *384 he was surrounded by uniformed police officers. She said "yes, that he was the person." He was wearing "the same black jacket that he had been wearing on the day he attacked [her]." (See fn. 3, ante.) He also had something on his head. Her assailant had not worn a hat, and the man she saw at the carwash had not worn a hat.

F. Charges and Proceedings

Defendant was charged by information with assault accompanied by intent to commit rape (Pen. Code, § 220), assault using a deadly weapon (Pen. Code, § 245, subd. (a)(1)), and indecent exposure (Pen. Code, § 314, subd. 1 (section 314(1))).[6] The trial court denied defendant's motion to try the assault separately from the indecent exposure charges. Before the jury, no defense was offered to the indecent exposure charges, but the assault charges were vigorously contested on the ground that Gloria's identification of defendant and his truck was mistaken. In support of that theory, the defense elicited testimony from an expert on eyewitness identifications, who was limited on prosecution motion to relevant general principles of perception and recollection. Jurors deliberated for five and one-half hours over two days. During deliberations they sought a readback of testimony concerning the language in which the assailant spoke. Ultimately the jury found defendant guilty of all charges and sustained an allegation that he had personally used a deadly weapon in the assault.
After trial, defendant failed to appear for a probation interview and then for a scheduled court hearing. He apparently remained at large for about five months. Upon his return to custody he was apparently charged with, and eventually entered a guilty plea to, willful failure to appear (Pen. Code, § 1320.5). The trial court sentenced him to consecutive terms of four years for assault with intent to commit rape, one year for personal use of a deadly weapon, and eight months for failure to appear, for an aggregate term of five years eight months.[7]
Defendant filed this timely appeal.


*385 DISCUSSION

I. Order Denying Separate Trials

In his motion to try the indecent exposure charge separately from the assault charge, defendant contended that the latter was relatively weak in that it depended on the credibility of the victim's identification of defendant and his vehicle.[8] Defense counsel contended in written argument that joint trials would be prejudicial because evidence of the indecent exposure, which would be inadmissible in a separate trial of the assault, would tend to make the jury think that he had committed the latter offense in part through improper inferences about criminal character. Defense counsel contended that the indecent exposure was "inflammatory" in the context of the assault charge, and constituted a strong case, which the prosecutor would use to bolster the weaker assault case by "aggregat[ing]" the evidence. The prosecutor did not submit written opposition, but argued at the hearing, among other things, that the two charges were admissible against each other and that the assault case was not weak in light of the victim's identification and the police artist's sketch, which he described as "incredibly similar, almost identical to a photograph of the defendant that was used in the photographic lineup . . . ."
In support of the motion, defense counsel submitted a declaration by Brian Abbott, Ph.D., a clinical and forensic psychologist with 28 years' experience in treating and evaluating sex offenders. Dr. Abbott declared that roughly 20 to 30 percent of criminal exhibitionists may also commit rape.[9] He drew a distinction between "primary exhibitionism," in which the actor finds exposing himself to be sexually gratifying in itself, and "transitional exhibitionism," in which "acts of indecent exposure serve as a psychological step toward engaging in hands-on sexually assaultive behavior." In the latter situation, the subject fantasizes about rape or other assaultive sexual behavior while exposing himself, and "[o]ver time, the repeated fantasizing about rape serves to breakdown [sic] the exhibitionist's inhibitions against acting in such ways." Because this progression is subject to various "social, physiological, and personality dynamics," it is impossible to predict which exhibitionists are likely to, or will, commit more serious offenses. In sum, "Exhibitionistic behavior alone cannot be considered indicative of or a precursor to an individual committing an act of rape. In fact, it is more likely exhibitionists will only engage in exhibitionistic behavior rather than to progress to acts of hands-on sexual assault, such as rape." Accordingly, "it would be inappropriate and prejudicial for a trier of fact to hear evidence that a person who *386 commits one or more acts of exhibitionism would be reasonably likely to commit rape in the future."[10]
The court denied the motion for separate trials. It explained its ruling only by saying, "the defendant has not shown that he's prejudiced by both charges being tried together . . . ."

II. Governing Principles

(1) Penal Code section 954 (section 954) addresses, among other things, the joinder of criminal charges in pleadings and their severance for trial. As relevant here it provides: "An accusatory pleading may charge two or more different offenses connected together in their commission, or different statements of the same offense or two or more different offenses of the same class of crimes or offenses, under separate counts . . . . [T]he court in which a case is triable, in the interests of justice and for good cause shown, may in its discretion order that the different offenses or counts set forth in the accusatory pleading be tried separately . . . ." (§ 954.)
The first of these clauses permits the prosecutor to combine multiple charges in a single accusatory pleading provided they meet the stated criteria, i.e., are "connected together in their commission, or [constitute] different statements of the same offense[,] or . . . [belong to] the same class of crimes or offenses . . . ." The second clause assumes that the charges have already been joined in the pleadings but empowers the court, "in its discretion," to order them tried separately "in the interests of justice and for good cause shown . . . ." (§ 954.) These provisions raise distinct questions: Whether the charges are eligible for joinder, i.e., satisfy the statutory criteria for joint pleading; and whether, despite their eligibility, they ought to be tried separately to ensure a fair trial. (See People v. Hill (1995) 34 Cal.App.4th 727, 734 [41 Cal.Rptr.2d 39] ["[E]ven where joinder is statutorily authorized, severance may be required if joinder results in prejudice so great as to deny the defendant a fair trial."].) Defendant contends that both of these questions point to error, i.e., that the indecent exposure charge was ineligible for joinder with the assault charge and that, even if the charges were properly joined in the first instance, they could not be fairly tried together. Because we find the latter point dispositive, we do not address the former.[11]
*387 The statute explicitly vests the trial court with discretion to determine whether to order separate trials. (§ 954.) This of course triggers the deferential abuse-of-discretion standard of appellate review. To successfully challenge the denial of a severance motion, an appellant must "make a `"clear showing of prejudice"'" and that the ruling "`"`"`falls outside the bounds of reason,'"'"'" (People v. Soper (2009) 45 Cal.4th 759, 774 [89 Cal.Rptr.3d 188, 200 P.3d 816] (Soper), italics omitted, quoting Alcala v. Superior Court (2008) 43 Cal.4th 1205, 1220 [78 Cal.Rptr.3d 272, 185 P.3d 708].) This demands a stronger showing than would be sufficient to require reversal based on the erroneous admission of evidence of uncharged crimes. (Soper, at p. 774.)
The trial court's denial of a motion to sever must be evaluated in light of the facts and circumstances apparent to the court at the time of its ruling. (Soper, supra, 45 Cal.4th at pp. 774-776, fn. 10.) However, "`[e]ven if a trial court's severance or joinder ruling is correct at the time it was made, a reviewing court must reverse the judgment if the "defendant shows that joinder actually resulted in `gross unfairness' amounting to a denial of due process."' [Citation.]" (People v. Macklem (2007) 149 Cal.App.4th 674, 698 [57 Cal.Rptr.3d 237]; accord, Soper, supra, 45 Cal.4th at pp. 782-783.)
(2) As indicated by the foregoing, the key inquiry before the trial court on a motion to sever is whether joint trials pose an unacceptable risk of prejudice, i.e., of unfairly affecting the adjudication of one or more of the charges. (See People v. Smith (2007) 40 Cal.4th 483, 510 [54 Cal.Rptr.3d 245, 150 P.3d 1224] ["To demonstrate that a denial of severance was reversible error, defendant must `"clearly establish that there [was] a substantial danger of prejudice requiring that the charges be separately tried."'"].) The chief source of potential prejudice is "spillover effect," i.e., the risk that evidence not admissible as to one of the charges, but admitted in connection with another, will affect the verdict on the charge as to which it is inadmissible. (See Soper, supra, 45 Cal.4th at pp. 775, 781.) Obviously there can be no spillover effect unless some of the evidence to be heard by the jury is *388 inadmissible as to at least one of the charges. Therefore the first consideration in evaluating a motion to sever is "cross-admissibility," i.e., the extent to which evidence of Charge A would have been admissible in a hypothetical separate trial of Charge B, and vice versa. (Soper, supra, 45 Cal.4th at pp. 774-775.)
If the jury will be exposed to evidence that is not cross-admissible, then the possibility of spillover effect is present and the court must proceed to evaluate the risk that the jury will be unfairly influenced by it. (Soper, supra, 45 Cal.4th at p. 775, quoting People v. Bean (1988) 46 Cal.3d 919, 938 [251 Cal.Rptr. 467, 760 P.2d 996] ["If we determine that evidence underlying properly joined charges would not be cross-admissible, we proceed to consider `whether the benefits of joinder were sufficiently substantial to outweigh the possible "spill-over" effect of the "other-crimes" evidence on the jury in its consideration of the evidence of defendant's guilt of each set of offenses.'"].) Courts have identified several factors to be considered in evaluating the risk. The pertinent ones here are whether the spillover evidence is likely to "`unusually inflame the jury against the defendant,'" and whether any of the charges as to which the evidence is not admissible rests on a "`weak case'" that may be unfairly bolstered by the spillover evidence. (Alcala v. Superior Court, supra, 43 Cal.4th 1205, 1220-1221, quoting People v. Mendoza (2000) 24 Cal.4th 130, 161 [99 Cal.Rptr.2d 485, 6 P.3d 150]; see Soper, supra, 45 Cal.4th at pp 775, 780.) In essence these are specific articulations of two broader variables: How likely is the spillover evidence to influence the jurors, and how susceptible is the charge to such influence? Once the spillover evidence has been identified and its potential to influence the verdict evaluated, the trial court must weigh the resulting risk of prejudice against the advantages of joint trials. (Soper, supra, 45 Cal.4th at p. 775.)
We now apply these principles to the case at hand.

III. Cross-admissibility


A. Introduction

We turn to the question of "cross-admissibility," i.e., the extent to which evidence offered to prove the indecent exposure charge would have been admissible to prove the assault charge, or vice versa. In support of the motion for separate trials, defense counsel asserted that there was no cross-admissible evidence in the case, adding, "[O]bviously, there are no witnesses or evidence that will be used in both charges . . . ." She argued that the indecent exposure and the assault were too dissimilar, too widely separated in time, and too *389 unrelated in occurrence for either to have any proper bearing on the other.[12] She also asserted that each charge would "rais[e] impermissible innuendoes of character" if introduced in a trial of the other. She expressed the prescient concern that "the People will try to promote that if a person would expose themselves that they are likely or probably would, in fact, commit the violent act of rape," adding that this would be an "inflammatory" use of the indecent exposure. These statements were sufficient to tender the issue whether, in a separate prosecution of the assault charge, evidence of the indecent exposure would be excluded on grounds that it was irrelevant, that its potential for prejudice outweighed any probative value it might be found to have, or that it violated the general prohibition against using evidence of bad character to prove the commission of a crime. (See Evid. Code, §§ 352 (section 352), 1101 (section 1101), subd. (a).)
The prosecutor contended orally that the assault evidence would be admissible in a separate trial of the indecent exposure, and vice versa, "under [Evidence Code section] 1108 and 1101[, subdivision] (b)."
The trial court expressed no opinion on cross-admissibility, instead reciting the boilerplate finding that defendant had failed to demonstrate that a joint trial would cause him undue prejudice.

B. Intent

Respondent suggests that the indecent exposure was relevant to the assault in that it could support an inference that the latter was committed with intent to commit rape, an element of one of the two aggravated assault charges. On the evidence before the jury, such an inference would be purely speculative. It necessarily rests on the supposition that where a man has criminally exposed himself on one occasion, and he thereafter commits an assault, it may reasonably be inferred from the exposure incident that he acted in the second incident for the purpose of committing rape rather than, e.g., to secure control of the victim in order to obtain property, or to express irrational rage. The evidence before the jury afforded no basis for such a supposition. For all the jury could know, criminal exhibitionists as a class might be characterized by an unusual inhibition against physical contact, and a particular inability to *390 commit sexual assault. They might thus be less likely than randomly selected members of the public to commit such a crime, or form the intent to do so. That this hypothesis is apparently contrary to the only expert opinion in the record, as discussed in more detail below, cannot sustain an inference the jury had no basis to draw.
Further, this theory begs the only real question in the case, which is whether defendant was the assailant. The proposed inference of intent necessarily supposes that he was; its necessary premise is that the indecent exposure and the assault were committed by the same person, i.e., defendant. But jurors were given many quite substantial reasons, discussed in detail below, to doubt this premise. At the same time, they had no reason at all to doubt that the purpose of the assault, whoever committed it, was to rape Gloria. According to her account of the attack, which went entirely unchallenged at trial, the assailant all but told her he intended to rape her. After expressly denying that he wanted money, he told her to stop struggling and to "allow [herself] to have it done . . . ." She described him as furiously stymied by the obstruction of her apron and "fairly tight pants . . . ."[13] Unless the jury simply refused to believe her accountin which case it would have acquitted defendant without worrying about the assailant's intentthere could be no doubt about the issue. The prosecutor told the jury as much early in his argument: "[T]here's no questionand . . . nothing to be disputed that the victim was assaulted by a person with the intent to commit rape." He soon repeated the point: "There's no question that the perpetrator was assaulting her with the intent to commit rape." We agree, as would any reasonable juror. Intent simply was not an issue on which a reasonable juror could entertain any doubtat least, not without doubting the entire prosecution case.
(3) This is not to suggest that a defendant can "limit the prosecution's evidence" merely by "`not putting things at issue.'" (People v. Thornton (2000) 85 Cal.App.4th 44, 48 [101 Cal.Rptr.2d 825].) A mere failure to contest an element of the prosecution's case cannot by itself bar evidence to *391 prove that element. But before potentially prejudicial evidence can be admitted to show an element of the offense there must be some concrete basis to suppose that the jury might fail to find that element beyond a reasonable doubt. (See People v. Balcom (1994) 7 Cal.4th 414, 423 [27 Cal.Rptr.2d 666, 867 P.2d 777] ["because the victim's testimony that defendant placed a gun to her head, if believed, constitutes compelling evidence of defendant's intent, evidence of defendant's uncharged similar offenses would be merely cumulative on this issue." "Accordingly, . . . the limited probative value of the evidence of uncharged offenses, to prove intent, is outweighed by the substantial prejudicial effect of such evidence"]; People v. Thornton, supra, 85 Cal.App.4th at p. 49) This was precisely the case here: even if the indecent exposure had possessed some logical tendency to establish the intent element of the assault chargewhich, again, it did notits probative value on that point was wholly theoretical, and it would have been a patent abuse of discretion to admit evidence of the indecent exposure for this purpose in a separate trial of the assault.
The dissent attempts to save this rationale by exploiting ambiguities in the term "intent." This approach is encapsulated in the assertion that "[t]he two offenses have very similar intent elements." (Dis. opn., post, at p. 418, fn. 4.) This is true, if at all, only in some lay sense, and an abstract, impressionistic one at that: paradigmatically, both crimes involve intentional sexual imposition upon, and at least potential insult to another, albeit psychological in one case and physical in the other. But if that gives them "very similar intent elements," then the same may be said of embezzlement and armed robbery. Indeed, all sex crimes have "very similar intent elements," and the point the dissent is attempting to refutethat the two crimes here shared nothing but their sexual characteris instead reinforced.
(4) The dissent's blurring of the concept of "intent" is also reflected in its assertion that the indecent exposure was relevant to intent because it "showed . . . defendant's sexual intent toward lone female strangers." (Dis. opn., post, at p. 424.) But as the dissent goes on to acknowledge, the requisite mental state for the assault charge was intent to commit rape, not "lewd sexual intent toward female strangers." (See dis. opn., post, at p. 424; see People v. Trotter (1984) 160 Cal.App.3d 1217, 1222 [207 Cal.Rptr. 165], quoting People v. Cortez (1970) 13 Cal.App.3d 317, 326 [91 Cal.Rptr. 660] ["Courts recognize `a distinction . . . between the intent to rape, and lewdness, indecency and lasciviousness either alone or accompanied by an intent to seduce.'"].) The proper use of the term "intent" in the present context is the mental elementthe mens reathat the prosecution is required to prove in order to make a prima facie case of guilt. (People v. Ewoldt (1994) 7 Cal.4th 380, 394, fn. 2 [27 Cal.Rptr.2d 646, 867 P.2d 757] ["Evidence of *392 intent is admissible to prove that, if the defendant committed the act alleged, he or she did so with the intent that comprises an element of the charged offense." (italics omitted)].) The mens rea for ordinary assault is a general intent to commit an act that "by its nature would directly and probably result in the application of force to someone . . . ." (CALCRIM No. 875; see People v. Colantuono (1994) 7 Cal.4th 206, 214 [26 Cal.Rptr.2d 908, 865 P.2d 704].) Assault with intent to commit rape further requires, as the name says, the specific intent to commit rape, i.e., sexual intercourse by force. (People v. Trotter, supra, 160 Cal.App.3d at p. 1224; see CALCRIM No. 890.) These elements bear no similarity to the mental elements for indecent exposure, which are that (1) the defendant acted "willfully" (§ 314(1)), meaning essentially that he knew he was exposing his genitals (see In re Smith (1972) 7 Cal.3d 362, 364 [102 Cal.Rptr. 335, 497 P.2d 807] (Smith)); (2) he "intended by his conduct to direct public attention to his genitals" (id. at p. 366); and (3) he acted "for purposes of sexual arousal, gratification, or affront" (ibid., fn. omitted).
(5) The dissent's attempt to equate these quite distinct mental states may be understood to rest on some conceptual or symbolic parallel between indecent exposure and rape in that a paradigmatic act of indecent exposure such as the one shown hereinvolves a kind of assault upon the victim's sensibilities. Perhaps the dissent means to imply that indecent exposure typically entails the infliction, or intent to inflict, a mental or emotional outrage or insult to the victim, which conceptually resembles the physical insult or outrage inflicted on the victim of a sexual assault. But this kind of symbolic comparison simply will not substitute for a focus on the actual elements of the offenses. Moreover, while insult is a common feature of the paradigmatic indecent exposure, it is not a necessary element of the crime. A purpose of "affront[ing]" the victim may satisfy part of the mens rea, but it is not necessary; the crime is also complete if the defendant acts for purposes of his own or the victim's (presumably imagined) "arousal" or "gratification," whether or not he intends to cause "affront" or believes he is doing so. (§ 314(1).)
The indecent exposure was simply not relevant to show the intent required for the assault charge, and could not be admitted for that purpose.

C. Motive

(6) Intermingled with respondent's argument on the issue of intent is the suggestion that the indecent exposure would have been admissible to show a sexual motive for the assault. Properly understood, the motive for a crime is never an issue in its own right, but may operate as a basis to establish identity on the rationale that the defendant's possession of a reason (motive) to *393 commit the charged offense increases the likelihood that he did so. The concept is familiar to anyone who has read or watched a detective story. One who stands to inherit money from a murder victim will routinely come under suspicion for the death, and if he is charged, the fact of his expectancy may be offered in court as circumstantial evidence that it was indeed he who killed the victim.
Here the attempt to justify the trial court's ruling on such a theory fails because defendant's commission of an indecent exposure simply could not show, without more, a motive to commit rapeexcept, yet again, through the undemonstrated premise that one who commits indecent exposure also wants, needs, or wishes to commit rape. Nor does the dissent appear to defend this theory of admissibilityexcept by blurring motive and intent, as in the assertion that the "quintessential element" of sexual assault is "the sexual motivation for the assaultthe intent to commit rape." (Dis. opn., post, at p. 418.) But motive is a much broader concept than intent; it is not an element of the offense at all; and it is relevant only insofar as it tends circumstantially to increase the likelihood that defendant, rather than another, committed the charged offense. Here no one questions that both crimes were sexually motivated. But many people other than defendant engage in some conduct for sexual motives. The question is in what conduct is defendant sexually motivated to engage? On this record, evidence of the indecent exposure had no tendency at all to show that he had a motive to commit sexual assault. The proposed inference of motive is no more logical than saying, "Joe manufactured methamphetamine, therefore he had a motive to steal a car." Without more, such a statement is simply a non sequitur.

D. Identity

Neither respondent nor the dissent makes any attempt to defend the use the prosecutor actually made of the indecent exposure evidence, which was to distract the jury from weaknesses in his own case on the issue of identity. Indeed the prosecutor explicitly cited the indecent exposure as "modus operandi" evidence, an implicit claim that it showed defendant, as opposed to someone else, to have been Gloria's assailant. He also claimed that the indecent exposure furnished a substitute for "DNA" in tying defendant to the assault.
(7) The evidence was patently irrelevant for any such purpose. Evidence of uncharged misconduct has long been admissible to prove identity when "the uncharged misconduct and the charged offense . . . share common features that are sufficiently distinctive so as to support the inference that the same person committed both acts." (People v. Ewoldt, supra, 7 Cal.4th at p. 403, italics added; accord, People v. Matson, supra, 13 Cal.3d at p. 40; *394 Soper, supra, 45 Cal.4th at p. 776.) But such an inference depends upon the presence of distinctive "marks" that are "shared by the uncharged and charged crimes." (People v. Thornton (1974) 11 Cal.3d 738, 756 [114 Cal.Rptr. 467, 523 P.2d 267], overruled on other grounds in People v. Flannel (1979) 25 Cal.3d 668, 684, fn. 12 [160 Cal.Rptr. 84, 603 P.2d 1].) "`[T]he inference of identity arises when the marks common to the charged and uncharged offenses, considered singly or in combination, logically operate to set the charged and uncharged offenses apart from other crimes of the same general variety and, in so doing, tend to suggest that the perpetrator of the uncharged offenses was the perpetrator of the charged offenses.'" (Thornton, at p. 756, italics added, quoting People v. Haston (1968) 69 Cal.2d 233, 245-246 [70 Cal.Rptr. 419, 444 P.2d 91].) "`The pattern and characteristics of the crimes must be so unusual and distinctive as to be like a signature.'" (Ewoldt, supra, 7 Cal.4th 380, 403; Soper, supra, 45 Cal.4th at p. 776.)
Similarly, an inference of identity can be drawn from "a distinctive modus operandi," but again, to be admissible on this basis, "the evidence must disclose common marks or identifiers, that, considered singly or in combination, support a strong inference that the defendant committed both crimes." (People v. Bradford (1997) 15 Cal.4th 1229, 1316 [65 Cal.Rptr.2d 145, 939 P.2d 259].) "These common marks must be distinctive rather than ordinary aspects of any such category of crime. They must be sufficiently distinctive that they bear defendant's unique `signature.' Reaching a conclusion that offenses are signature crimes requires a comparison of the degree of distinctiveness of shared marks with the common or minimally distinctive aspects of each crime." (People v. Bean (1988) 46 Cal.3d 919, 937 [251 Cal.Rptr. 467, 760 P.2d 996], italics added.)
(8) Obviously the two incidents here share no "marks" distinguishing them from other indecent exposures or other sexual assaults. Both involved taking advantage of unwilling victims, but this is true of all attempted rapes and many, if not the vast majority of, indecent exposures. Certainly this feature is not so distinctive as to set these two crimes apart. Much the same is true of the prosecutor's argument to the jury that the crimes had the same perpetrator because the offender in both cases "sought out a woman that was alone while he was using his car." Elsewhere he described the perpetrator as singling out a victim "using his own vehicle[,] [a]nd when she tried to escape, he followed her." Gina's somewhat confusing testimony could be understood to mean that defendant made some attempt to follow her after initially exposing himself, but there is no evidence that the assailant attempted to follow Gloria after she escaped his grasp and fled. This leaves the commonplace facts that the offender in both cases used an automobile instead of traveling to and from the scene by foot, bicycle, or helicopterand *395 that he chose a victim who was alone rather than one in a position to readily secure aid. The choice of an isolated victim does not remotely approach the level of distinctiveness required to support an inference of identity. "By their very nature," most sex crimes are "committed in seclusion without third party witnesses or substantial corroborating evidence." (People v. Falsetta (1999) 21 Cal.4th 903, 915 [89 Cal.Rptr.2d 847, 986 P.2d 182]; see People v. Thomas (1978) 20 Cal.3d 457, 468 [143 Cal.Rptr. 215, 573 P.2d 433] [noting the "circumstances of privacy and seclusion surrounding the commission of most sex offenses"], impliedly overruled on another point in People v. Tassell (1984) 36 Cal.3d 77, 87-89 & fn. 8 [201 Cal.Rptr. 567, 679 P.2d 1], as stated in People v. Alcala (1984) 36 Cal.3d 604, 634, fn. 18 [205 Cal.Rptr. 775, 685 P.2d 1126].) Nor does anything distinctive appear in the mere use of a vehicle, particularly where, as here, it is not the same vehicle or used in the same manner. The indecent exposure was committed from within the perpetrator's vehicle; he never left it. The assailant, in contrast, parked away from the victim, snuck up on her, and carried out the attack inside her vehicle. The only feature the two crimes really had in common, aside from their sexual character, was that the perpetrator traveled to and from them by car. Given the obvious advantages of a private automobile for this purpose, it is hardly surprising that innumerable cases share the same feature. (See People v. Bean, supra, 46 Cal.3d at p. 937 [several common features, including taking and abandoning victim's car, lacked sufficient distinctiveness to establish modus operandi].)
The two crimes had no distinguishing characteristics in common.[14] They simply were not similar. They did not even involve the same, or notably similar, actsa "mark" that may ordinarily be taken for granted in cases involving the use of uncharged crimes to prove identity. It is one thing to find a man guilty of armed robbery based on his previous commission of that offense. But to base such a finding on an act of shoplifting passes beyond speculation into the realm of hunch or fancy. Here the jury had no rational basis to infer from the facts surrounding the indecent exposure that it was defendant and not someone else who committed the far more serious, violent offense of sexual assault, on another occasion, under entirely different *396 circumstances. The indecent exposure was simply not relevant to any issue in the assault case and could not have been introduced in evidence in a separate trial of that case.

E. Propensity

The only colorable basis for admitting evidence of the indecent exposure in a hypothetical separate trial of the assault would have been that it was admissible under Evidence Code section 1108 to show that defendant had a propensity or predisposition to commit sexual assault. The prosecutor alluded to this theory, respondent defends it, and the dissent endorses it in passing. In our view it presents two distinct questions: whether Evidence Code section 1108's exception to the rule against propensity evidence extends to proof of a wholly different crime; and whether, assuming it does, evidence of defendant's indecent exposure had any tendency in reason, on the evidence before the jury, to establish such a predisposition. We do not finally reach the first question, but we answer the second with a resounding negative.
(9) It is of course the general rule that evidence of uncharged misconduct is not admissible to prove a predisposition to such conduct, even when it would otherwise be relevant to establish misconduct on a specific occasion such as the occasion of a charged criminal offense. (See § 1101, subd. (a).) Although the rule is codified in rather indirect terms, its gist is that parties in both civil and criminal cases are generally prohibited from introducing evidence of a general character for good or bad conduct, or a predisposition or propensity to engage in conduct of a particular kind, to show conduct on a particular occasion. (See ibid.) Evidence Code section 1108 creates an exception to this rule, though again the point is expressed rather obliquely: "In a criminal action in which the defendant is accused of a sexual offense, evidence of the defendant's commission of another sexual offense or offenses is not made inadmissible by Section 1101, if the evidence is not inadmissible pursuant to Section 352." (Evid. Code, § 1108, subd. (a).)
According to its sponsor, the statute was intended "to provide explicitly that evidence of other offenses within the scope of the section is not subject to § 1101's prohibition of evidence of character or disposition," and thereby to "permit[] courts to admit such evidence on a common sense basis without a precondition of finding a `non-character' purpose for which it is relevant . . . ." (Letter by Assemblyman Rogan regarding Assem. Bill No. 882 (1995-1996 Reg. Sess.) published in 2 Assem. J. (1995-1996 Reg. Sess.) p. 3278, reprinted at 29B pt. 3 West's Ann. Evid. Code (1999 pocket supp.) foll. § 1108, at pp. 40-41 [bill was "modeled on Rules 413-15 of the Federal *397 Rules of Evidence, and adapts the principle of these rules to the framework of California law"].) The object is to allow "rational assessment by juries of evidence so admitted. This includes consideration of the other sexual offenses as evidence of the defendant's disposition to commit such crimes, and for its [sic] bearing on the probability or improbability that the defendant has been falsely or mistakenly accused of such an offense." (Ibid.; see People v. Reliford (2003) 29 Cal.4th 1007, 1009 [130 Cal.Rptr.2d 254, 62 P.3d 601] [Evid. Code, § 1108 "allows evidence of the defendant's uncharged sex crimes to be introduced in a sex offense prosecution to demonstrate the defendant's disposition to commit such crimes" (italics added)].)
The statute "implicitly abrogates prior decisions . . . indicating that `propensity' evidence is per se unduly prejudicial to the defense." (People v. Falsetta, supra, 21 Cal.4th 903, 911; see People v. Abilez (2007) 41 Cal.4th 472, 502 [61 Cal.Rptr.3d 526, 161 P.3d 58] (Abilez).) Its purpose, however, was to relax the traditional limits, not abolish them. Thus a trial court may not "`admit or exclude every sex offense a defendant commits,'" but must "`consider [other] factors'" bearing on the relevance, probative value, and prejudicial potential of the evidence, including "`its similarity to the charged offense.'" (Abilez, supra, 41 Cal.4th at p. 502, quoting Falsetta, supra, 21 Cal.4th at p. 917, italics added in Abilez.) Obviously, the "lack of similarity" between charged and uncharged offenses can be enough by itself to justify an exclusion of the latter in an exercise of the trial court's discretion. (Abilez, supra, 41 Cal.4th at p. 502.) Logically, it can also be enough to compel its exclusion where, as here, any inference of predisposition to commit the charged offense would be wholly speculative, i.e., where the uncharged offense has no tendency in reason to show that the defendant actually has the propensity whose proof the statute authorizes.
The statute would clearly authorize the admission of evidence of an indecent exposure in a second prosecution for indecent exposure, on the rationale that the defendant's commission of the first crime supports an inference that he is predisposed to such conduct, and that since it shared the same essential nature as the conduct underlying the charged offense, its occurrence increased the likelihood that the defendant committed that offense. However, the statute cannot infuse an uncharged offense with relevance or probative value it cannot rationally be found to possess. In order for evidence of another crime to be relevant under Evidence Code section 1108, it must have some tendency in reason to show that the defendant is predisposed to engage in conduct of the type charged. (See People v. Soto (1998) 64 Cal.App.4th 966, 989 [75 Cal.Rptr.2d 605] ["`A defendant with a propensity to commit acts similar to the charged crime is more likely to have committed the charged crime than another.'"].) (italics added)].) If the uncharged crime *398 does not rationally support such an inference, then it is simply irrelevant in a prosecution for the charged one.
(10) Does the commission of indecent exposure rationally support an inference that the perpetrator has a propensity or predisposition to commit rape? Not without some kind of expert testimony, it does not.[15] "[P]ropensity" refers to "[a] predisposition or inclination to, towards, or for a particular action, habit, quality, etc.; a tendency to do something." (Oxford English Dict, (draft rev. Sep. 2008)  [as of Mar. 19, 2009], italics added.) Similarly, "predisposition" is "[t]he condition of being predisposed or inclined beforehand (to do something, or to a particular opinion, course of action, etc.); a prior inclination or pre-existing tendency." (Id.,  [as of Mar. 19, 2009], italics added.) As the use of "tendency" here reflects, both terms refer to a constant, or at least recurring, inclination. (See Oxford English Dict. (2d ed. 1989)  [as of Mar. 19, 2009] [defining "tendency" as "[t]he fact or quality of tending to something; a constant disposition to move or act in some direction or toward some point, end, or purpose; leaning, inclination, bias, or bent toward some object, effect, or result" (italics added)].)
There is of course substantial basis to suppose that many sexual offenses arise from a persistent or recurring compulsion, desire, appetite, or drive on the defendant's part to engage in such conduct. Such a drive constitutes propensity of a kind, and probably a forcefulness, wholly unlike the psychological processes actuating most criminal offenses.[16] It is probably safe to say that most people have not the slightest inclination to lewdly expose their *399 genitals to strangers, no matter how perfect an opportunity might arise. Those who do engage in such conduct, at least in the paradigmatic manner shown here, typically act not from any circumstantial or situational motive, but from a persistent and recurring desire to exhibit their sex organs. Because the desire is typically persistent and recurring, it is a good bet that someone who commits this act once will be predisposed to commit it again (and again). This provides a solid foundation for a focused inference that a defendant, having criminally exposed himself on one occasion, will do so again. This in turn adds weight to an accusation that he has done so again.
(11) But a propensity to commit one kind of sex act cannot be supposed, without further evidentiary foundation, to demonstrate a propensity to commit a different act. The psychological manuals are full of paraphilias, from clothing fetishes to self-mutilation, some of which are criminal, some of which are not. No layperson can do more than guess at the extent, if any, to which a person predisposed to one kind of deviant sexual conduct may be predisposed to another kind of deviant sexual conduct, criminal or otherwise. Is one who commits an act of necrophilia (Health & Saf. Code, § 7052) more likely than a randomly selected person to commit an act of rape? Child molestation? Indecent exposure? Is a pedophile more likely than a rapist or a member of the public to commit necrophilia? Without some evidence on the subject, a jury cannot answer these questions.
Certainly these questions cannot rationally be answered, as the dissent would answer them, by drawing abstract conceptual analogies between one kind of sexual misconduct and another. That they all involve some kind of outrage against an unconsenting person (or, in the one case, a former person) can hardly justify any particular inference about the likelihood that one such activity shows a predilection for another. Most crimes can be conceptualized as outrages or impositions against one or more unconsenting persons. That does not make it rational to suppose that the perpetrator of one crime will commit another crime of a substantially different character. If anything such speculation may be even more unwarranted in the case of sexual misconduct, which may reflect highly particularized, compulsive activity rather than opportunistic, situational, or impulsive conduct. Here the dissent would impliedly justify an inference of predisposition by equating the psychic distress inflicted by a criminal exhibitionist to the physical and potentially lethal violence inflicted by a rapist. That is not a reasoned inference; it is sheer guesswork.
*400 This is not to assert as a fact that criminal exhibitionists are no more likely than other members of the public to commit sexual assault. The expert declaration submitted by the defenseto the court, not the juryto establish the prejudicial effect of trying the two charges together showed a correlation between the two types of misconduct. But it is a weak one: according to the studies there summarized, nearly three out of four indecent exposers will not commit rape, and at least three out of four rapists have not committed indecent exposure. Whether that correlation would be sufficient to permit introduction of this evidence on a proper foundation is a question we do not and need not reach, for the prosecution made no attempt to lay any such foundation. The jury therefore had no rational basis on which to draw even the weak inference this evidence might sustain.
On the evidence actually before the jury, defendant's commission of indecent exposure was simply irrelevant to the assault charge, i.e., it had no tendency in reason to show that he committed the latter offense. As we have said, Evidence Code section 1108 does not purport to make irrelevant evidence relevant. It therefore furnished no justification to admit the indecent exposure in a separate trial of the assault.

IV. Potential Spillover Effect


A. Inflammatory Tendency

Having concluded that evidence of the indecent exposure was spillover evidence as to the assault charge, we must assess its potential to prejudicially affect the jury's assessment of that charge. (Soper, supra, 45 Cal.4th at p. 775.) In noncapital cases, this inquiry typically revolves around two factors: the extent to which the spillover evidence was particularly "`likely to unusually inflame the jury against the defendant,'" and the extent to which "`a weak case [was] joined with a strong case . . . so that the total evidence m[ight] alter the outcome of some or all of the charges . . . .'" (Alcala v. Superior Court, supra, 43 Cal.4th 1205, 1220-1221; see Soper, supra, 45 Cal.4th at p. 775.)
The presence of the first factor here is debatable. Surely in many contexts an act of indecent exposure would not be expected to "inflame" a jury's sentiments, however obnoxious they might find it. Notwithstanding its loathsomeness, it remains a distinctly nonviolent offense. (See In re Lynch (1972) 8 Cal.3d 410, 429-431 [105 Cal.Rptr. 217, 503 P.2d 921] (Lynch).) While its commission often appears "`intended to evoke fear and shock'" (id. at p. 430, quoting Gigeroff et al., Sex Offenders on Probation: The Exhibitionist (1968) 32 Fed.Prob. (No. 3) 17, 19), no such effect is necessary to its completion. So long as the defendant acts with the requisite intent, the crime *401 requires only that the exposure occur in a "public place" or in the presence of "other persons to be offended or annoyed thereby...." (§ 314(1).) The second phrase is satisfied so long as "there are persons present who may . . . be `offended or annoyed' ...." (Lynch, supra, 8 Cal.3d at p. 431, italics added.) The same is probably also true of the first. (See Pryor v. Municipal Court (1979) 25 Cal.3d 238, 244 [158 Cal.Rptr. 330, 599 P.2d 636] [saving disorderly conduct statute from vagueness challenge by construing "public place" to require actual or constructive knowledge "of the presence of persons who may be offended by the conduct"].) Traditionally the crime received relatively mild punishment, and apart from the potential magnifying effects of recidivism, that remains true today. (People v. Massicot (2002) 97 Cal.App.4th 920, 928 [118 Cal.Rptr.2d 705], citing Lynch, supra, 8 Cal.3d 410, 429-431.)
On the other hand, in the context of the assault case here the exposure charge may well have had the potential to inflame the jury against defendant in an unusual and peculiar manner. The entire defense consisted of raising doubts based on weaknesses in Gloria's identification of defendant and his truck. As a repellent sexual aberrationwhat is still widely known as a "perversion"the indecent exposure would naturally incline the jury to view defendant as a kind of freak, a pariah, a "pervert." This would at a minimum reduce the jurors' natural compunction about convicting him of the more serious offense on questionable evidence, as well as impairing their ability to view evidence of that offense objectively. Further, as discussed in more detail below, the prosecutor's arguments to the jury tended to considerably amplify the inflammatory potential of the indecent exposure by furnishing the predicate to characterize defendant as a "predator" and "scary guy." (See pts. IV.B., V., post.) We are satisfied that in the context of the heavily contested assault charges here, these arguments gave a particularly inflammatory tendency to the evidence of indecent exposure.

B. Weak Case Bolstered by a Strong Case

The indecent exposure case was extremely strong. The unimpeached testimony of the victim established that the exposure was perpetrated by a man who looked exactly like defendant and who was driving defendant's car. The victim positively identified defendant from a photographic lineup the fairness and reliability of which was not questioned. There simply was no rational basis for the jury to doubt that it was in fact defendant who exposed himself to Gina. Defense counsel acknowledged the strength of this evidence and tacitly conceded her client's guilt.[17]
*402 In stark contrast to this seemingly unassailable showing, the evidence in the assault case was vulnerable to attack on a number of grounds. Indeed, while there was no reason to doubt that Gloria sincerely believed defendant was the assailant, virtually every part of her testimony on that subject presented discrepancies sufficient to lead a reasonable juror to entertain serious doubts about defendant's guilt.
First, Gloria described her assailant as a Hispanic male. She denied using the term "Hispanic," but acknowledged telling police that her assailant looked "Mexican American." She testified that she used the term "Pocho," meaning, "someone who was born here and has Mexican parents." She considered him "Mexican-American as opposed to just Mexican," but the "American" component was not based on appearance; rather it rested on "the way he was speaking Spanish, that he didn't speak it well."
The record indicates that this attribution of a distinctly Hispanic appearance simply did not match defendant. The officer who filled out booking documents after defendant's arrest recorded his ethnicity as "[w]hite."[18] The prosecutor elicited testimony from Detective Gutierrez that Gloria "identified" her assailant as "a light-skinned Hispanic male...." But Gloria herself testified that the assailant's skin was "light brown," not "light," and described it as "[s]imilar" to her own. Neither of the two mug shots in evidence shows defendant with a skin shade comparable to the distinctly olive tone in a photograph of Gloria. Instead they fully bear out the description of him as "white." One shows him with an extremely pale complexion and sandy *403 colored hair. In the other neither his hair nor his complexion looks so pale, but his skin tone is far from what anyone would call "light brown."
Nor was there any other evidence suggesting that defendant looked Hispanic. Indeed Gloria herself was not asked whether defendant, as he sat in the courtroom or was depicted in the photographs, looked "Pocho" to her. Further, while no testimony was sought from Gina Doe about the apparent ethnicity of the man who exposed himself to her, a telling inference may be based upon the photographic lineup from which she identified defendant. Of the six photographs selected by police for the array, undoubtedly based on Gina's description, none had skin darker than one would expect in a person of northern European heritage. Only one had dark hair and eyes; and at least twoother than defendantlooked distinctly Nordic, Teutonic, or Slavic, with pale skin, blond hair, and light eyes.
In sum, so far as this record shows, Gloria's assailant looked Hispanic, while defendant did not. This serious weakness in the prosecutor's case is reflected in his repeated resort to speculation and surmise entirely outside the evidence. Thus he argued that a person's ethnicity is often "a question of impression" and that some people defy ethnic categorization, implying that the assailant, and thus defendant, might have been "half Mexican and half white" or "a very light-skinned Hispanic...." In doing so he ignored, and manifestly hoped the jury would ignore, Gloria's own testimony that the assailant's skin color was "light brown" and "similar" to hers, and that the only thing that seemed "American" about the assailant was his poor Spanish.
The prosecutor also insisted that there was "no evidence to say the defendant is not Hispanic," and that apart from the booking officer's entry, there was "no evidence presented in this case to say he is white...." But apart from the issue of the burden of proof, the question was not defendant's actual ethnicity; it was whether he looked like the assailant described by Gloria, and particularly as described by her before she decided defendant was the man. The prosecutor's own insistence that a person can have Mexican genes and still look "white" was a tacit concession that defendant did look "white" and did not have, as Gloria said her assailant had, "light brown skin." Nothing in this record supports a contrary view.
One point on which Gloria's description of her assailant did nearly match defendant was her estimate that he stood about five feet nine inches tall, which is one inch shorter than defendant. The prosecutor laid great emphasis on the nearness of this estimate. But even here there was considerable room to doubt Gloria's testimony. At trial she said she had told police her assailant was "between 5'6 to 5'8, more or less," which would make him two to four *404 inches shorter than defendant. Moreover a jury viewing the evidence dispassionately might observe that height was the assailant's one outward feature Gloria would seem to have been least able to accurately judge. According to her, she was already sitting part way in her car when the assailant suddenly appeared at the driver's door and "threw" her "back into the car," apparently meaning further into the car. Thereafter neither of them was standing from the beginning of the assault until after she pushed herself out the opposite door, got up off the ground, and ran. The only indication that she ever saw the assailant while both were standing was her testimony that after seeking help at the bakery she "ran over to the corner and saw [the assailant] get into this truck that he had parked there." But she also testified that "the guy from the bakery was with me" at this time, and that person, Armondo Romero, described no such thing. All he saw was "a pickup truck pass by."
The prosecution faced a further difficulty in Gloria's description of the assailant to police as "[t]hin, skinny." Defendant was certainly lean, apparently weighing about 180 pounds at the time of his arrest, but he was very far from "skinny." Both photographs suggest the build of a wrestler. Indeed this is one of the more striking divergences between photographs of defendant and the police sketch, which depicts a distinctly thin-necked and narrow-faced person, in contrast to defendant's bull neck and broad face. Other evidenceincluding the pictorial exhibitssuggested that defendant had some prominent physical features that Gloria never mentioned to officers, and did not at trial recall seeing on the assailant. These included distinctly protruding ears, a deeply furrowed brow, a receding hairline, and, apparently, "highlights" in his hair.
Another weakness in the prosecution's case was the unexplained ineffectuality, and ultimate failure, of the assault. Although the record does not disclose Gloria's height and weight, the prosecutor conceded in argument that she was shorter and less strong than defendant. At the same time, the jury heard testimony that defendant held a black belt in the martial art of Brazilian jujitsu, and was a high-ranked world-class contender in that sport as well the sport of "submission grappling." Defendant's hypothetical identity as Gloria's assailant may thus seem at odds with her having out-grappled her assailant and fled the scene.
Gloria's identification was also rendered vulnerable by her adamance coupled with a manifest eagerness to bring about the apprehension and punishment of her assailant. She told Detective Gutierrez that she was "100 percent sure that the defendant was the man who attacked her...." But she acknowledged that after the attack she was afraid and "wanted the person *405 who did this to [her] to be caught." When she identified defendant in the in-field showup, she "had already decided at the car wash ... that's the person that attacked [her]...." She had formed that conclusion while watching defendant, as she said, "from afar"too far to see his eyes, height, weight, or whether he was Hispanic, or to read the truck's license plate. She acknowledged that when she saw the black truck outside the carwash, she "got a little bit scared because it was a black truck." But she also assented to assertions that she was "sure that that's the truck and the person that attacked you," "even though it was not a Ford Bronco," and even though she could not see the driver's height or weight, and that she "just felt sure that that was the person...."
These features made Gloria's testimony particularly vulnerable in light of the expert testimony of Professor Geoffrey Loftus, offered by the defense concerning the potential unreliability of eyewitness identifications. Compressed to its essentials, this testimony informed the jurors that reported memories may not only be rendered inaccurate by deficiencies in the witness's original perception, but may in effect be corrupted by information later encountered and incorporated into memory. Thus, "every time you think about some event that you've experienced in the past, every time you revisit it in your memory, your memory will change in some fashion or another.... [¶] . . . [¶] . . . [A]s a result of all this kind of reconstructive processes, memory . . . can change . . . and does change over time, sometimes fairly dramatically. So that by the time a person is called upon to recount what happened to them, their recollections, their memory of what happened may be very different from the memory that they laid down at the time that the original event was taking place."
Of particular relevance was the professor's warning against reliance on a witness's subjective confidence as an indicator of reliability. "[T]housands of experiments," he said, show that "people can report memories . . . with a great deal of confidence . . . that are just dead wrong in many important respects." "[M]emory reconstruction" played a role in various criminal convictions based on mistaken identification, a "large majority" of which involved "faulty eyewitness testimony, witnesses identifying the defendant. . . often quite confidently, but incorrectly, as it turns out." In some cases where people were exonerated on the basis of DNA evidence, they had been "misidentified by numerous eyewitnesses." He opined that a witness's adamance about the correctness of his or her identification should be completely disregarded in assessing the reliability of identification testimony.
Despite its generalitywhich was partly the result of a successful motion in limine by the prosecutionthis testimony brought out several factors, not otherwise obvious to the jury, that could well cast Gloria's identification into *406 doubt. For example, it could highlight the serious deficiencies in the conditions under which she observed her assailant. Although she was certainly viewing him at close range throughout the struggle, the lighting consisted entirely of whatever illumination entered her car from the parking lot lights above it. Aside from its relative dimness, the overhead orientation of such lighting would naturally cast much or all of the assailant's face into deep shadow. Moreover, Gloria testified that for much or all of the struggle, the assailant was pulling her head back by the hair. This would seem likely to direct her gaze upward and to make it more difficult to look directly at his faceunless his face itself was above her, in which case it would have been entirely in shadow. The possibility of "weapon focus" was also present, for she not only saw a knife but was told by the assailant that he had a gun.
Further serious weaknesses attended Gloria's identification of defendant's truck as matching that of the assailant. Gloria initially specified a make and model of trucka "1986 Ford Bronco"that simply did not match defendant's 1981 Chevrolet Blazer. Although Gloria testified that she did not "know that much about the makes of cars," she acknowledged having a friend who drove a Bronco. She herself drove a sport utility vehiclea 2003 GMC Envoywhich she described as "my truck."
Further, whatever Gloria knew or did not know about the names of various models, when she saw another Ford Bronco a week after the assault she took down its license number and told police she thought she had found the assailant's vehicle.[19] Thus, in order to find beyond a reasonable doubt that the assailant was driving defendant's truck, the jury had to accept that Gloria was mistaken not only in initially describing a different vehicle but in subsequently recognizing a vehicle that matched her original description, but not defendant's truck.
The prosecution sought to get over this difficulty by emphasizing the similar body styles of Blazers and Broncos. But apart from the debatable sufficiency of this consideration to meet the issue, its underlying premise, and Gloria's truck identification in its entirety, were cast in doubt from an entirely independent source: the testimony of bakery worker Armondo Romero, the only other person to see the assailant's vehicle, who described it not as a sport utility vehicle, but as a "pickup truck." In her final comments to the jury, defense counsel cited this discrepancy as one of five respects in which the evidence raised a reasonable doubt as to defendant's guilt. The prosecutor's only response was to refer to defendant's truck as a "pickup truck" and *407 then to suggest in argument that both a Bronco and a Blazer are "basically,. . . pickup trucks with shells on the back." It is unclear whether this was intended to confuse the jury, or perhaps to invite speculation that Mr. Romero had mistaken defendant's Blazer for a pickup truck with a shell. When Mr. Romero was on the stand, the prosecutor had made no attempt to establish that the "pickup" he saw might have had a shell. By alluding to such a possibility in jury argument, he was simply fabricating facts out of thin air, and inviting the jurors to do likewise.
These circumstancesmost notably Gloria's contested original description of the vehicle, its later metamorphosis from a Bronco to a Blazer, the questionable viewing conditions preceding her "decision" that defendant was the assailant, and the highly suggestive circumstances of her formal identificationswould have suggested to a reasonable juror, versed in the testimony of Professor Loftus, that her identification of defendant and his truck could well rest on after-the-fact reconstructions rather than accurately retrieved original perceptions. As defense counsel pointed out, everything Gloria remembered about the assailant and his vehicle seemed to be revised in a flash two and a half weeks after the event, when she saw defendant sitting in his Blazer and formed the conviction that he was the culprit. At that moment, a skeptical juror could quite reasonably conclude, the assailant metamorphosed from Hispanic to European, from light brown to white, from skinny to muscular; his vehicle metamorphosed from a 1986 Ford to a 1981 Chevrolet; and its rear window vanished. This is not the stuff of strong cases.[20]

V. Countervailing Benefits

(12) Once the spillover evidence has been identified and its potential to influence the verdict evaluated, the trial court must weigh the resulting risk of prejudice against the advantages of joint trials. (Soper, supra, 45 Cal.4th at p. 775.) The greatest advantages will often be those stemming from the avoidance of duplication of evidence, as where at least some of the same testimony, or testimony from the same witnesses, would be heard in each of *408 the hypothetical separate trials. (See Alcala v. Superior Court, supra, 43 Cal.4th 1205, 1218 ["`"joinder prevents repetition of evidence and saves time and expense to the state as well as to the defendant"'"].) In these cases, joint trials may serve not only the interests of the state, but those of third persons, most obviously by sparing one or more citizen witnesses from having to testify more than once.
Even where no case-specific economies appear, we are directed by the Supreme Court to weigh, as against the risk of prejudice, the "systemic economies" of joint trials, i.e., the savings in costs otherwise incurred by the state in a second trial and appeal. (Soper, supra, 45 Cal.4th at p. 782; see id. at pp. 772, 781-783.) We do not understand the court to mean that these "systemic economies" will always be enough, by themselves, to sustain a refusal to sever. Rather the court was explaining its conclusion that the Court of Appeal there had "inappropriately minimized the benefits of joinder" when it dismissed the benefits as "minimal." (Soper, supra, 45 Cal.4th at p. 781.) The court's point was that reviewing courts must not take lightly the public benefits that flow from the administrative savings that flow from disposing of multiple charges in a single proceeding. (See Soper, supra, 45 Cal.4th at p. 782.)
Here the "systemic economies" were the only advantages of joint trial. There was absolutely no overlap in the evidence or witnesses. So far as the evidence was concerned, the matter essentially took the form of two trials before a single jury. The time spent actually trying the indecent exposure was minimal; the relevant testimony takes up approximately 22 pages of transcript. Therefore the only apparent savings was the time and cost to impanel a second jury to hear that evidence separately. This is not a trivial matter; in all likelihood, it would have consumed more time than the actual taking of evidence, and probably the deliberations as well. Moreover we do not disregard the fact that however honorable and necessary jury duty may be, it incommodes 12 citizens who would otherwise remain free to pursue their own concerns.[21]
(13) Ponderable as these interests are, however, we do not believe they can counterbalance the very substantial risk that evidence of the indecent exposure played a dispositive role in the verdict on the assault charge. Obviously a balance must be struck between economy and convenience on the one hand, and accuracy and fairness on the other. Each of the signatories of this lead opinion has served as the presiding judge of a major metropolitan trial court. In that role we have been responsible for the efficient allocation of resources that never seemed to keep pace with our court's burgeoning *409 caseload. We are therefore far from insensitive to concerns about the economical use of those resources. But it would never occur to us, and we trust it would never occur to any judge, to elevate those concerns above an accused person's right to a fair trialincluding the right to be tried (and convicted, if that is the result) only upon evidence the law allows the fact finder to consider. Such an ordering of priorities would be irreconcilable with the basic consensus on which our society rests, and would strike a blow at the requirement of due process of law which is the beating heart of our republic. We are confident that the Supreme Court had no such intention when it admonished reviewing courts to take due account of "systemic economies." Those economies simply were not enough here to justify a joint trial.
There is no suggestion that, with the possible exception of the actual jury arguments made by the prosecutor, any of the factors we have identified were unforeseeable at the time the trial court made its ruling. The basic outlines of the case, and the general use the prosecution made of the indecent exposure, were apparent from the preliminary hearing onwards, and were accurately forecast by defense counsel in support of the motion for separate trials. Because we do not believe that a reasoned discretion could reach any other conclusion than that separate trials were necessary to avoid undue prejudice, we hold that the trial court abused its discretion by denying the motion seeking such trials.

VI. Due Process; Actual Prejudice

(14) Even where the information of record fails to show that the trial court abused its discretion in denying a motion for separate trials, we are still obliged to reverse if the appellate record shows that "`the joinder of counts or defendants for trial resulted in gross unfairness depriving the defendant of due process of law.'" (Soper, supra, 45 Cal.4th at p. 783, quoting People v. Rogers (2006) 39 Cal.4th 826, 851 [48 Cal.Rptr.3d 1, 141 P.3d 135].) Although this rule places a "high burden" on the appealing defendant (Soper, supra, 45 Cal.4th at p. 783), the present record satisfies that burden. Having reviewed it with some care, we find compelling evidence that the joint trials inflicted actual prejudice upon defendant. Indeed, we find a considerable likelihood that had the jury not heard evidence of the indecent exposure, it would not have found defendant guilty of the assault.
Short of statements by the jurors themselves, nothing could more vividly demonstrate the crucial role played by the indecent exposure in securing the assault conviction than the prosecutor's own heavy and pervasive reliance on it in jury argument. It is no exaggeration to say that he mentioned the indecent exposure at every opportunity, on every conceivable pretext, and for every possible purpose. In his opening argument he characterized the exposure incident as "[p]robably the most powerful evidence" that defendant was *410 Gloria's assailant. He urged the jury to view it as the equivalent of genetic evidence, asserting, "We don't have any DNA . . . [b]ut what we do have is powerful powerful corroboration. And that is the defendant's indecent exposure three months prior to the assault." (Italics added.) He repeated the point a few minutes later, saying, "We don't have DNA but we do have the fact he committed this 314 [i.e., indecent exposure]."
Next he told the jurors that criminal exhibitionism furnishes evidence of propensity to commit rape. This argument rested not on evidence, but on an invented psychiatric reality. Thus he invited jurors to "think, what's the state of mind of a guy who's going to be mast[u]rbating in front of a woman and get her attention drawn to himself[?]" Before the jurors could actually follow this suggestion to speculate on their own, or perhaps to realize that they had no idea what goes on in the mind of a criminal exhibitionist, he helpfully supplied his own inflammatory surmise: "So we go into this whole analysis as to whether or not he's the perpetrator of the assault to commit rape from the premise that this is a man who is mast[u]rbating in front of a woman, who called attention to herto himself, three months before. [¶] This man is a predator. He's building up. He's starting small. He exposes himself. [¶] Is it really a stretch to think that his next step, three months later, because he gets so agitated, for whatever reason, whatever his state of mind, is he decides to commit a sexual assault[?]" (Italics added.)
We have already adverted to the inherent potential of the indecent exposure to convey an inflammatory impression of defendant as a deviant or pervert. In addition, the power of the term "predator" to incite passion and prejudice can hardly be overstated. The term connotes, if it does not denote, one who habitually commits sex offenses characterized by violence, pedophilia, or both. Thus, with one inconsequential exception, California prescriptive law speaks only of sexually violent predators, a phrase defined to include pedophiles. (See Welf. & Inst. Code, § 6600 et seq. [Sexually Violent Predator Act (SVPA)]; cf. Ballot Pamp., Gen. Elec. (Nov. 7, 2006) text of Prop. 83, p. 127 [initiative amending SVPA entitled "The Sexual Predator Punishment and Control Act: Jessica's Law"].) The distinction between violent and nonviolent sex crimes is recognized throughout the relevant literature. One commentary defines "`sexual aggressors'" to include, as relevant here, "all those who have engaged in sexual acts involving physical contact with a child or nonconsensual sexually violent acts against adults (i.e., offenses involving the use of force in such a way that the sexual integrity of the victim was violated)." (2 Faigman et al., Modern Scientific Evidence: The Law and Science of Expert Testimony (2008) § 11.24, pp. 203-204, italics added.)
Defense counsel quite properly objected to the prosecutor's psychiatric speculations, stating, "There's no evidence as to this argument." The court *411 not only overruled the objection, but invited the jury to give the prosecutor's argument whatever credence it chose: "The jury has already been admonished that evidence is to be decided from the testimony of witnesses. You have some latitude with respect to argument. [¶] They can give it whatever weight they want." (Italics added.)
Shortly thereafter the prosecutor returned to the theme that, based upon the indecent exposure, defendant was a loathsome and dangerous pariah. On the pretext of discussing motive, he asserted that defendant "is a sexual deviant because he mast[u]rbated in front of [Gina Doe]." (Italics added.) He went on to characterize defendant, based solely on the indecent exposure, as "a scary guy" and, again, a "predator."
These argumentsand thus the indecent exposure evidencestruck at the heart of the identity defense by inviting the jury to substitute anti-"deviant" bias for a reasoned analysis of the evidence. Virtually every time the prosecutor acknowledged the question of identity he cited or alluded to the indecent exposure as an answer. Just as predicted in the defense motion for separate trials, he repeatedly lumped the two offenses together in the manifest hope that the certainty of defendant's commission of the lesser crime would cure the uncertainties attending the greater. Thus he argued, "So how do we know it was the defendant[?] How do we know that the man in court today is the man who committed these crimes against these two women? [¶] Well, [Gina Doe's] identification of the defendant [for the indecent exposure] has gone completely unimpeached . . . . There's no dispute about that. [¶] . . . I'd be surprised if the defense made an argument that he was not the one that committed the . . . indecent exposure on [Gina]." Shortly thereafter, he explicitly invited the jury to consider the indecent exposure as evidence that defendant was the assailant: "[I]n making your decision, you need to consider all of the evidence. And you can consider all of the evidence that was presented in this trial, every piece of evidence. You can consider the facts behind what happened to [Gina Doe] in deciding the offenses in . . . the assault cases." (Italics added.)
Because there was ample reason for a jury to entertain a reasonable doubt that Gloria had correctly identified her assailant, it is entirely possible, if not likely, that a jury not exposed to evidence of the indecent exposure incident, and the use the prosecutor made of it, would have acquitted defendant of the assault. We must therefore conclude that the trial court's denial of the motion for separate trials, if not an abuse of discretion, resulted in such gross unfairness as to deprive defendant of a fair trial and thus of due process of law. This conclusion makes it unnecessary to address defendant's other claims of error or to address his petition for habeas corpus.


*412 DISPOSITION
In No. H031525, the judgment of conviction on the charge of indecent exposure is affirmed. The judgment on the counts charging assault is reversed for further proceedings in accordance with this opinion. In No. H032982, the petition is dismissed as moot.
Premo, J., concurred.
MIHARA, J., Dissenting.
I respectfully dissent. The majority opinion spends a great deal of time analyzing evidence presented at trial that might have led a fact finder to entertain a reasonable doubt as to whether defendant was the perpetrator of the assault. Yet the existence of evidence that could have supported a reasonable doubt is of minimal relevance to the issues actually before us in this case. Severance is not required merely because the evidence is strong as to one count and could support a reasonable doubt as to the other. Instead, the determination of whether to sever counts is committed to the discretion of the trial court, which must balance a number of relevant factors. Unlike my colleagues, I would find no abuse of discretion in the trial court's denial of defendant's severance motion. I would also conclude that defendant was not denied due process by the joint trial of the indecent exposure and assault offenses. As there were no other prejudicial errors, I would affirm the judgment.

I. Factual Background
On September 30, 2004, about 4:00 p.m., Gina[1] was walking into the mobilehome park where she lived. She saw a white Ford Probe next to her that was moving very slowly. The man driving the car said "[c]ome here." He spoke English. Gina approached the passenger window of the car and noticed that the man driving the car was naked from the waist down and was masturbating. Gina ran to the manager's house, and the man parked in front of that house. Gina wrote down the license number of the man's car. No one was home at the manager's house, so Gina ran to the manager's office. As she ran, she called out "Julio," and the man drove off. Gina ran home and called the police. In October 2004, Gina identified a photograph of defendant in a photo lineup as the man she had seen masturbating in the Ford Probe. Defendant's residence was 2.3 miles from the mobilehome park.
At 5:00 a.m. on December 30, 2004, Gloria parked her car in the parking lot of the shopping center where she worked at an outdoor table selling *413 tamales in front of a market. The shopping center was 2.4 miles from the mobilehome park where Gina lived and about 4 miles from defendant's residence. Although it was dark outside, the area was lit by street lights and lights in the parking lot. No one was around when Gloria began unloading her equipment from her car in front of the market. As Gloria was getting back into her car to reposition it, a man appeared at her car door. She asked if he could help her, and he grabbed her and pushed her into the car. Although the light in her car was not on, Gloria could see her assailant's face due to the parking lot lights. Her assailant grabbed her hair and pulled it back. Gloria held onto the steering wheel so that her assailant would not be able to force her to lie down.
She asked him if he wanted money, and he said no. He told her to stop struggling and "allow myself to have it done . . . ." Gloria does not speak English, and her assailant spoke to her in "kind of broken half Spanish." He said he had a gun and a knife. Gloria saw a small knife in his hand. She kept struggling, and her assailant "seemed to become even more aggressive." He kept pulling her hair "really hard." During their struggle, he cut her hand with his knife, although she did not notice it at the time. Gloria got a good look at his face, which was just six inches away from her face. Finally, Gloria was able to lift up her leg and push her assailant out of the car. She pushed "as hard as I could and I shot out the [passenger] door on the other side." Gloria saw her assailant go toward the back of the bakery which was adjacent to the market.
Gloria ran to the bakery screaming for help. Armondo Romero, who worked at the bakery, came out of the bakery to help her. Gloria saw her assailant drive off from behind the bakery in a black "truck" similar to a Ford Bronco. She noticed that the vehicle was missing its back window. Romero also saw the vehicle, which he described as a dark-colored pickup truck. The police arrived in about 10 minutes.
Gloria described her assailant to the police as a five-foot, nine-inch tall man who was thin and in his mid-20's. He had dark brown hair and light skin, and she thought he might be "Mexican American" because of his broken Spanish. His hair was short and combed back, and he was wearing a black jacket. She told the police that his vehicle was a black Ford Bronco from around 1986, although she was not certain about the year.
A few days after the attack, Gloria saw a parked black Ford Bronco that was similar to the vehicle her assailant had been driving. She contacted the police, but it was determined that this Bronco was not involved in the attack.
*414 A week after the attack, Gloria met with a police sketch artist who produced a sketch of her assailant from her description. Gloria felt that this sketch was "pretty close" to depicting her assailant.
A couple of weeks after the attack, Gloria was inside a building at a carwash when she saw defendant sitting in his truck in a nearby parking lot. Gloria was certain that defendant was the man who had assaulted her. Gloria tried unsuccessfully to telephone the police. Defendant kept moving his truck around from one parking space to another. Eventually he drove into another parking lot across the street, and Gloria followed him on foot. When the truck turned around and headed toward her, she ducked into a store and was able to write down the truck's license plate number as it passed the store. The truck was missing its rear window. After noting the license plate number, Gloria called the police again, and she and her brother followed the truck a few blocks to a house, where the truck parked. Defendant got out of the truck and went into his residence. Gloria and her brother remained in their car, a few houses away, awaiting the arrival of the police.
The police arrived and brought defendant out of the house. Gloria identified defendant as her assailant. He was wearing the same black jacket that he had been wearing when he assaulted her. Defendant's truck was a 1981 Chevy Blazer. Ford Broncos and Chevy Blazers were "somewhat similar" in the 1980's. The sketch of Gloria's assailant was similar to a photograph of defendant taken in 2002. Defendant was a 28-year-old White man who was five feet 10 inches tall and weighed 180 pounds. He was the registered owner of both the white Ford Probe that bore the license plate number recorded by Gina, and the black 1981 Chevy Blazer that Gloria had trailed from the carwash to defendant's home. A small retractable knife was found in defendant's home.

II. Procedural Background
Defendant was charged by information with assault with intent to commit rape (Pen. Code, § 220), assault with a deadly weapon (Pen. Code, § 245, subd. (a)(1)), and indecent exposure (Pen. Code, § 314, subd. 1). It was further alleged that defendant had personally used a dangerous or deadly weapon in the commission of the assault with intent to commit rape (Pen. Code, § 12022, subd. (b)).
At trial, Gloria made an in-court identification of defendant, and the jury had an opportunity to observe defendant's appearance, including his face and his body. The defense presented expert testimony on "human perception and human memory" to challenge the accuracy of Gloria's identification of defendant as her assailant. A friend of defendant testified at trial that *415 defendant is one of the top-ranked Americans in Brazilian Jujitsu, a martial art in which leverage is utilized for self-defense and "ground fighting."
After about a day of deliberations, the jury returned guilty verdicts on all three counts and found the personal use allegation true. Defendant, who was free on bail, failed to appear for sentencing, and he was charged with failure to appear while released on bail (Pen. Code, § 1320.5). He pleaded guilty to that count and was sentenced to a total of five years eight months in prison for all of his convictions.[2] Defendant filed a timely notice of appeal.

III. Discussion

A. Joint Trial of Indecent Exposure and Assault Counts

1. Background
The indecent exposure count was consolidated with the other counts in advance of the preliminary examination. Defendant moved in limine to sever the indecent exposure count from the other counts. His motion implicitly conceded that the assault with intent to commit rape count and the indecent exposure count were "of the same class of crimes." He claimed that severance should be ordered because a joint trial would substantially prejudice him. Defendant argued that the indecent exposure evidence was not cross-admissible, and a joint trial would pair a weak case (the assault) with a strong case (the indecent exposure) to his prejudice.
The defense submitted an expert's affidavit in support of its contention that the commission of the indecent exposure offense was not probative as to propensity to commit a sex offense. The expert opined that "[e]xhibitionist behavior alone cannot be considered indicative of or a precursor to an individual committing an act of rape. . . . A small proportion of exhibitionists are known to commit acts of rape." The underlying data cited by the expert in his affidavit indicated that about a quarter of exhibitionists commit rape and about a quarter of rapists have a history of exhibitionism.
At the hearing on the in limine motion, defendant's trial counsel argued that the indecent exposure evidence was not cross-admissible, and that the indecent exposure case was a strong case involving "minimal conduct" that would be joined with the weaker, more inflammatory assault case. Defendant's trial counsel relied on the expert's affidavit to support her claim that evidence of the indecent exposure was not probative as to the assault. She *416 argued that "it's prejudicial to join the two counts." The prosecutor argued that evidence of the indecent exposure was cross-admissible under Evidence Code sections 1101, subdivision (b) and 1108. The court denied the severance motion on the ground that defendant would not be unduly prejudiced by a joint trial.
In his opening argument to the jury, the prosecutor told the jury that it could "consider the facts behind what happened to [Gina] in deciding the offenses in Counts One and Two, the assault cases." "We don't have DNA but we do have the fact he committed this 314 [indecent exposure]." "The modus operandi was absolutely the same, ladies and gentlemen. He sought out a woman that was alone while he was using his car."
Defendant's trial counsel conceded in closing argument that defendant was guilty of the indecent exposure count. Defendant's trial counsel argued that the indecent exposure offense was so different from the assault that it did nothing to support a finding that defendant had committed the assault.
The prosecutor argued in his closing argument that the indecent exposure offense was circumstantial evidence that could be considered on the assault counts. "And it's important to remember when you're deciding the evidence you can consider all of the facts. [¶] You need to decide each count separately, but you can consider all of the facts, with all of the counts. When deciding each count, you're not limitedyou don't have to say, we can only consider what [Gloria] says. You need to consider everything."

2. Consolidation
Defendant's initial contention is that the indecent exposure count should never have been consolidated with the assault with intent to commit rape count in the first place, because the two counts were not "of the same class of crimes or offenses" within the meaning of Penal Code section 954.[3]
"An accusatory pleading may charge two or more different offenses connected together in their commission, or different statements of the same offense or two or more different offenses of the same class of crimes or offenses, under separate counts . . .; provided, that the court in which a case is triable, in the interests of justice and for good cause shown, may in its *417 discretion order that the different offenses or counts set forth in the accusatory pleading be tried separately . . . ." (Pen. Code, § 954, italics added.) The phrase of "`"`the same class of crimes'"'" means "`"offenses possessing common characteristics or attributes."'" (People v. Kemp (1961) 55 Cal.2d 458, 476 [11 Cal.Rptr. 361, 359 P.2d 913].) Appellate courts exercise independent review in resolving whether the offenses are "`of the same class'" within the meaning of Penal Code section 954. (People v. Alvarez (1996) 14 Cal.4th 155, 188 [58 Cal.Rptr.2d 385, 926 P.2d 365].)
A person commits indecent exposure when he or she willfully and lewdly exposes his or her private parts in a public place. (Pen. Code, § 314, subd. 1.) The exposure must be "sexually motivated." (In re Smith (1972) 7 Cal.3d 362, 366 [102 Cal.Rptr. 335, 497 P.2d 807].) The prohibition against indecent exposure is contained in title 9 of part 1 of the Penal Code, which contains "Crimes Against the Person Involving Sexual Assault, and Crimes Against Public Decency." A person commits an assault with intent to commit rape when he or she assaults another with the intent to commit rape. (Pen. Code, § 220.) The prohibition against assault with intent to commit rape is contained in title 8 of part 1 of the Penal Code, which contains "Crimes Against the Person." There are many types of rape, but rape generally refers to an act of sexual intercourse that is accomplished against another's will by force. (Pen. Code, § 261.) Like the prohibition against indecent exposure, the prohibition against rape is contained in title 9 of part 1 of the Penal Code.
In People v. Maury (2003) 30 Cal.4th 342 [133 Cal.Rptr.2d 561, 68 P.3d 1] (Maury), the California Supreme Court found that murder and rape were "`of the same class of crimes'" because they were both "assaultive crimes against the person" and therefore were properly joined under Penal Code section 954. (Maury, at p. 395.) Maury is instructive. The prohibition against murder, like the prohibition against assault with intent to commit rape, is contained in title 8 of part 1 of the Penal Code. The prohibition against rape, like the prohibition against indecent exposure, is contained in title 9. Murder and rape have in common that they are assaultive acts against a person; assault with intent to commit rape and indecent exposure have in common that they are sexually motivated acts. Murder and rape are of a class of assaultive crimes on persons; assault with intent to commit rape and indecent exposure are of a class of sexually motivated crimes. Assault with intent to commit rape and indecent exposure are "of the same class of crimes" within the meaning of Penal Code section 954 because these two crimes possess a common characteristicsexual motivation.
Defendant argues that two offenses are not of the "same class" unless they are "generically" similar and share a "common element of substantial importance." Offenses must share a "`common element of substantial importance'" to qualify for joinder as "`connected together in their commission'" *418 under Penal Code section 954. (People v. Matson (1974) 13 Cal.3d 35, 39 [117 Cal.Rptr. 664, 528 P.2d 752].) However, offenses may alternatively qualify for joinder if they are "of the same class of crimes." If the "common element of substantial importance" requirement applied to the "same class of crimes," the "same class of crimes" language in Penal Code section 954 would be surplusage.
Moreover, indecent exposure and assault with intent to commit rape do share a "common element of substantial importance." The quintessential element of assault with intent to commit rape is the sexual motivation for the assaultthe intent to commit rape. The quintessential element of indecent exposure is the sexual motivation for the exposurethe lewd intent. Hence, these two offenses do share a common element of substantial importancea sexually motivated act.[4] The consolidation of the indecent exposure count with the assault with intent to commit rape count did not violate Penal Code section 954.

3. Denial of Severance Motion
Defendant asserts that the trial court prejudicially erred in denying his motion to sever the indecent exposure count from the assault counts.
"The prosecution is entitled to join offenses under the circumstances specified in section 954. The burden is on the party seeking severance to clearly establish that there is a substantial danger of prejudice requiring that the charges be separately tried. [Citations.] When the offenses are [properly] joined for trial the defendant's guilt of all the offenses is at issue and the problem of confusing the jury with collateral matters does not arise. The other-crimes evidence does not relate to [an] offense for which the defendant may have escaped punishment. That the evidence would otherwise be inadmissible may be considered as a factor suggesting possible prejudice, but countervailing considerations that are not present when evidence of uncharged offenses is offered must be weighed in ruling on a severance motion. The burden is on the defendant therefore to persuade the court that these countervailing considerations are outweighed by a substantial danger of undue prejudice." (People v. Bean (1988) 46 Cal.3d 919, 938-939 [251 Cal.Rptr. 467, 760 P.2d 996].)
"Not only is the burden allocated differently in cases involving properly joined charges as compared with cases involving the introduction of uncharged misconduct, but the nature of the abuse of discretion standardand *419 the ensuing method utilized to analyze prejudice, undertaken to determine whether a trial court abused its discretion in a specific casealso are significantly different from what is employed in determining whether a trial court erred in allowing the introduction of evidence of uncharged misconduct." (People v. Soper (2009) 45 Cal.4th 759, 774 [89 Cal.Rptr.3d 188, 200 P.3d 816] (Soper).)
"To demonstrate that a denial of severance was reversible error, defendant must `"clearly establish that there [was] a substantial danger of prejudice requiring that the charges be separately tried."'" (People v. Smith (2007) 40 Cal.4th 483, 510 [54 Cal.Rptr.3d 245, 150 P.3d 1224].) "A trial court's denial of a motion for severance of charged offenses amounts to a prejudicial abuse of discretion if the `"trial court's ruling `"falls outside the bounds of reason."'"' [Citation.] In making that assessment, we consider the record before the trial court when it made its ruling. [Citation.] `The factors to be considered are these: (1) the cross-admissibility of the evidence in separate trials; (2) whether some of the charges are likely to unusually inflame the jury against the defendant; (3) whether a weak case has been joined with a strong case or another weak case so that the total evidence may alter the outcome of some or all of the charges; and (4) whether one of the charges is a capital offense, or the joinder of the charges converts the matter into a capital case.' [Citations.] `The state's interest in joinder gives the court broader discretion in ruling on a motion for severance than it has in ruling on admissibility of evidence.'" (Alcala v. Superior Court (2008) 43 Cal.4th 1205, 1220-1221 [78 Cal.Rptr.3d 272, 185 P.3d 708] (Alcala).)
Defendant claims that the admission of evidence of the indecent exposure offense at a joint trial posed a substantial danger of prejudice to him with respect to his identity defense to the assault counts. Consideration of the relevant factors does not support his claim that the trial court abused its discretion in concluding otherwise.
Cross-admissibility is the key factor. "If the evidence in each case is shown to be cross-admissible in the others, ordinarily any inference of prejudice from joinder of charges is dispelled." (People v. Sully (1991) 53 Cal.3d 1195, 1222 [283 Cal.Rptr. 144, 812 P.2d 163].) The prosecutor argued below that evidence of the indecent exposure would have been admissible under Evidence Code sections 1101, subdivision (b) and 1108 at a separate trial of the assault counts.[5] Evidence of an uncharged crime is admissible under Evidence Code section 1101, subdivision (b) "when relevant to prove some *420 fact (such as motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake or accident . . . ." (Evid. Code, § 1101, subd. (b).) Evidence Code section 1108 permits the admission of evidence of an uncharged sexual offense to prove disposition in a sex offense prosecution. (Evid. Code, § 1108, subd. (a).)
Defendant claims, and the majority opinion accepts, that there was no dispute at trial about the intent for his assault on Gloria. On this basis, they maintain that the admission of evidence of the indecent exposure offense under Evidence Code section 1101, subdivision (b) at a separate trial on the assault counts would have been prohibited as cumulative and unnecessary. I disagree. The severance motion was ruled on in limine, and the prosecution remained under the burden of proving that the perpetrator of the assault intended to commit rape. In light of the absence of any evidence that Gloria's assailant touched, or attempted to touch, her private parts, attempted to remove her clothing, or unequivocally expressed any sexual intent, the trial court could have concluded that evidence of defendant's sexual intent, in the form of his indecent exposure offense, was probative on the specific intent element of the assault count.
"The least degree of similarity (between the uncharged act and the charged offense) is required in order to prove intent." (People v. Ewoldt (1994) 7 Cal.4th 380, 402 [27 Cal.Rptr.2d 646, 867 P.2d 757] (Ewoldt).) "In order to be admissible to prove intent, the uncharged misconduct must be sufficiently similar to support the inference that the defendant `"probably harbor[ed] the same intent in each instance." [Citations.]'" (Ewoldt, at p. 402.) The indecent exposure offense was "sufficiently similar" to the assault offense to support the inference that defendant probably harbored the same intent on both occasions. The fact that, just three months before the assault, defendant approached a female stranger who was alone, summoned her to his car window, and lewdly exposed his private parts to her tended to show that, when defendant approached the car window of another lone female stranger, he harbored a similar lewd intent. Consequently, evidence of the indecent exposure offense would have been admissible in a separate trial of the assault count under Evidence Code section 1101, subdivision (b).
Defendant and the majority also contend that evidence of the indecent exposure offense would not have been admissible under Evidence Code section 1108 in a separate trial of the assault counts to prove that defendant was disposed to commit rape. They assert that the defense produced evidence at the in limine hearing that exhibitionists are not likely to commit rape, and the prosecution failed to produce evidence that exhibitionists are likely to commit rape. In their view, the indecent exposure evidence was therefore not relevant to show a disposition to commit rape. I disagree.
*421 It is simply not true, as the majority opinion asserts, that the jury lacked a rational basis for drawing a relevant inference in the absence of expert testimony that it was more likely than not that an exhibitionist, in the abstract, would commit rape.[6] The trial court was not obligated to credit the defense expert's declaration, and it could also reasonably conclude that the jury would not face the abstract question addressed by the expert. Here, the question of fact that would be placed before the jury at trial was whether a man who summoned a lone female stranger to his car window to view his exposed erect penis was likely to commit other sexually motivated offenses against lone female strangers. The trial court could have reasonably concluded that these specific facts provided a rational basis for drawing such an inference. On this basis, the court could have concluded that the evidence was admissible under Evidence Code section 1108.
Defendant maintains that the trial court could not have concluded that the indecent exposure would have been admissible in a separate trial of the assault counts because the admissibility of the indecent exposure evidence depended upon an Evidence Code section 352 analysis.[7] Not so. "[A]lthough in the context of evidence of uncharged offenses offered at trial, a court conducts an assessment concerning prejudice under Evidence Code section 352 [citation], by contrast, in the context of properly joined offenses, `a party seeking severance must make a stronger showing of potential prejudice than would be necessary to exclude other-crimes evidence in a severed trial' [citation]. In the context of properly joined offenses, we assess potential prejudice not under Evidence Code section 352, but instead in the context of the traditional four factors outlined above: cross-admissibility of charges; tendency of the charges to inflame the jury; the bolstering of a weak case; and the conversion of noncapital charges into a capital case." (Alcala, supra, 43 Cal.4th at p. 1222, fn. 11.) The trial court was not required to conduct an Evidence Code section 352 analysis in considering the cross-admissibility of the indecent exposure evidence.
Defendant implicitly concedes that, where there is cross-admissibility, the other factors need not be considered. However, the majority opinion devotes considerable attention to these other factors. I can find no abuse of discretion in the trial court's conclusion that the remaining factors did not preclude the joint trial of these counts.
*422 While the indecent exposure case was strong, the assault case was not as weak as the majority opinion contends. The majority opinion's analysis of the alleged weakness of the assault count is premised on the validity of defendant's various challenges in the trial court to the reliability of Gloria's identification of him and his vehicle. Yet the defense case was fully presented to the jury and rejected by it. Gloria's descriptions of her assailant and his vehicle immediately after the assault were consistent with defendant and his vehicle. The sketch produced from her description was, as the prosecution argued and the defense conceded at trial, quite similar to a photograph of defendant, and Gloria identified the black jacket defendant was wearing at the time of his arrest as the black jacket worn by her assailant. The indecent exposure case was significantly stronger than the assault case due to the license plate number linking defendant's vehicle to the offense, but the discrepancy was not nearly so vast as the majority opinion claims.
Finally, the indecent exposure count was hardly inflammatory in comparison to the assault counts. The assault counts involved very violent conduct, the use of a knife, and the infliction of a knife wound on Gloria, while the indecent exposure count was committed without any physical contact between defendant and Gina.
These factors provide no support for a finding that the trial court abused its discretion. The majority opinion disregards the fact that our review of the trial court's ruling is highly deferential. The sole factor favoring severance was the imbalance in the strength of the evidence between the two counts. "A mere imbalance in the evidence, however, will not indicate a risk of prejudicial `spillover effect,' militating against the benefits of joinder and warranting severance of properly joined charges. [Citation.] Furthermore, the benefits of joinder are not outweighedand severance is not required merely because properly joined charges might make it more difficult for a defendant to avoid conviction compared with his or her chances were the charges to be separately tried." (Soper, supra, 45 Cal.4th at p. 781.) Here, the indecent exposure offense was cross-admissible and was not inflammatory, and the benefits of joinder were substantial.
"[T]he benefits to the state, in the form of conservation of judicial resources and public funds . . . often weigh strongly against severance of properly joined charges." (Soper, supra, 45 Cal.4th at p. 774, citation omitted.) "[A]s a general matter, a single trial of properly joined charges promotes important systemic economies. Whenever properly joined charges are severed, the burden on the public court system of processing the charges is substantially increased. Even assuming that some level of economy might be preserved by (when possible) appointing or assigning the same counsel, investigators, and paralegals to prosecute and defend each charge separately, *423 merely segmenting the proceedings typically will result in inefficiency. For example, each of the numerous procedural steps attendant to any criminal proceedingsuch as discovery, pretrial motions, as well as trial sessions themselveswould proceed on discrete tracks. Additionally, when two previously joined matters advance to separate trials, approximately twice as many prospective jurors would need to be summoned and subjected to the selection process.
"Further amplifying these and related trial-level inefficiencies resulting from separate trials is the appeal of right afforded to all convicted criminal defendants. Separate appellate records would be compiled by the clerk's offices of the respective trial courts. Even assuming the same appellate counsel could be appointed or assigned to represent the parties, once again merely segmenting the proceedings generally will cause inefficiency. Furthermore, the Court of Appeal, through its own clerk's office, would be required to manage and process discrete appeals, and provide an opportunity for separate oral arguments. Individual written decisions would be drafted, considered, and filed. Subsequently, separate petitions for rehearing could be filed in the Court of Appeal, followed by individual petitions for review in [the California Supreme] court. T[he California Supreme] court, in turn, would need to process, analyze, and dispose of each. Thereafter, separate collateral reviews at the three levels of the federal court systemreprising versions of many of the procedures outlined abovecould ensue.
"Although our courts work diligently to ensure due process in all proceedings, their resources are limited. California's trial courts in particular face ever-increasing civil and criminal dockets without any guarantee of corresponding, additional funds for court servicesjudges, judicial staff, and clerk's office personnelto meet the demand. Today, no less than in the past, the opportunity for joinder and its attendant efficiencies provided by section 954 is integral to the operation of our public court system. Manifestly, severance of properly joined charges denies the state the substantial benefits of efficiency and conservation of resources otherwise afforded by section 954." (Soper, supra, 45 Cal.4th at p. 782.)
Hence, the trial court could have reasonably concluded that the imbalance in the evidence did not pose such a high danger of undue prejudice as to require the severance of these counts. Thus, I would find no abuse of discretion in the trial court's denial of defendant's severance motion.

4. Due Process
Defendant also urges that the joint trial of the indecent exposure and assault counts resulted in such gross unfairness that he was denied due *424 process. "Even if a trial court's severance or joinder ruling is correct at the time it was made, a reviewing court must reverse the judgment if the `defendant shows that joinder actually resulted in "gross unfairness" amounting to a denial of due process.'" (People v. Mendoza (2000) 24 Cal.4th 130, 162 [99 Cal.Rptr.2d 485, 6 P.3d 150].) Defendant claims that he was unfairly prejudiced by the lack of a limiting instruction restricting the jury's use of the indecent exposure in determining his guilt on the assault counts, and by the prosecutor's improper reliance on the indecent exposure in closing argument.

a. Lack of Limiting Instruction
Defendant claims that he was unduly prejudiced because the trial court failed to sua sponte give the jury a limiting instruction on the uses to which the jury could put evidence of the indecent exposure in determining defendant's guilt on the assault counts. "The trial court has no sua sponte duty to give a limiting instruction on cross-admissible evidence in a trial of multiple crimes." (Maury, supra, 30 Cal.4th at p. 394.) Even if there is an exception to this rule where the joined offense was "`a dominant part of the evidence against the accused [on the other offenses], and is both highly prejudicial and minimally relevant to any legitimate purpose'" (People v. Rogers (2006) 39 Cal.4th 826, 854 [48 Cal.Rptr.3d 1, 141 P.3d 135]), such an exception would not apply here.
The indecent exposure evidence was more than minimally relevant because it showed both defendant's sexual intent toward lone female strangers and his propensity to commit sexually motivated acts against them. And it was not a "dominant part of the evidence" against defendant on the assault counts. The assault counts were primarily premised on Gloria's testimony. The prosecutor simply relied on the indecent exposure evidence to corroborate Gloria. In his closing argument, the prosecutor explained: "I'm not bootstrapping and I'm not asking you to convict Mr. Earle of Counts one and two [the assault counts] because he's guilty of count three [the indecent exposure count], absolutely not, and it would be wrong to do that." "The purpose of count three and the reason I'm arguing it is not to say, oh, well, he did that so he's therefore, definitely guilty of counts one and two. [¶] It's to say and explain, and hopefully clarify for you, that when [Gloria] says, `that's the guy.' You understand and realize that it's not a mistake, that it's not a coincidence, because under the defense theory, it's a mistaken identity." Because the indecent exposure evidence had significant relevance on intent and propensity as to the assault count, the trial court was not obligated to give a limiting instruction sua sponte.
Nor was it unreasonable for defendant's trial counsel to fail to request a limiting instruction. A limiting instruction would have highlighted the fact *425 that the indecent exposure evidence was admissible to show defendant's propensity for committing sexually motivated crimes. "A reasonable attorney may have tactically concluded that the risk of a limiting instruction . . . outweighed the questionable benefits such instruction would provide." (Maury, supra, 30 Cal.4th at p. 394.)
Since a limiting instruction could have done defendant more harm than good, its absence did not unduly prejudice him or deny him a fair trial.

b. Prosecutorial Argument
Defendant also asserts that the joint trial of the indecent exposure count and the assault count enabled the prosecutor to use derogatory epithets, and make improper comments about defendant's motive and modus operandi, in his argument to the jury.
At the conclusion of the trial, the court instructed the jury: "Statements made by the attorneys during the trial are not evidence." And the court told the jury: "Each count charges a distinct crime. You must decide each count separately. The defendant may be found not guilty or guilty of any or all of the crimes charged." The prosecutor thereafter argued to the jury: "Probably the most powerful evidence, we don't have any DNA, Ladies and Gentlemen. But what we do have is powerful powerful corroboration. And that is the defendant's indecent exposure three months prior to the assault." After noting that the defense had not challenged Gina's testimony that defendant was the man who had exposed himself to her, the prosecutor asserted: "This man is a predator. He's building up. He's starting small. He exposes himself. [¶] Is it really a stretch to think that his next step, three months later, because he gets so agitated, for whatever reason, whatever his state of mind, is he decides to commit a sexual assault." At this point, defendant's trial counsel objected: "Objection, your honor. There's no evidence as to this argument." The court responded: "The jury has already been admonished that evidence is to be decided from the testimony of witnesses. You have some latitude with respect to argument. [¶] They can give it whatever weight they want."
The prosecutor subsequently argued that defendant had the means, motive, and opportunity to commit the assault on Gloria. "`Motive' we know the defendant is a sexual deviant because he masterbated [sic] in front of [Gina]. There's no question he's sexually deviant. What kind of person is going to call a woman up to his car. She walks up to him. He's got no pants on and he's masterbating [sic]. This is a scary guy." At the conclusion of the prosecutor's opening argument, he again said that defendant had committed the indecent exposure and "[h]e is a predator." "His behavior in indecent exposure establishes he's a predator. His behavior when he assaulted [Gloria] establishes he's a predator."
*426 Defendant claims that he was unduly prejudiced by the prosecutor's improper argument, based solely on the indecent exposure, that defendant was a "predator," "a sexual deviant," and "a scary guy." While these epithets carried a certain power, it is only undue prejudice that must be avoided, "not the prejudice or damage to a defense that naturally flows from relevant, highly probative evidence." (People v. Karis (1988) 46 Cal.3d 612, 638 [250 Cal.Rptr. 659, 758 P.2d 1189].) "A prosecutor is given wide latitude during closing argument. The argument may be vigorous as long as it is a fair comment on the evidence, which can include reasonable inferences or deductions to be drawn therefrom. `"A prosecutor may `vigorously argue his case and is not limited to "Chesterfieldian politeness"' [citation], and he may `use appropriate epithets . . . .'" [Citations.]'" (People v. Harrison (2005) 35 Cal.4th 208, 244 [25 Cal.Rptr.3d 224, 106 P.3d 895] (Harrison).)
An act is "predatory" if it "exploit[s] others for personal gain or profit." (Merriam-Webster's Collegiate Dict. (10th ed. 1993) p. 917 (Webster's).) Defendant's indecent exposure exploited Gina for defendant's sexual enjoyment and therefore it was a predatory act. A sexual "deviant" is a person who engages in sexual behavior that departs "significantly from the behavioral norms" of society. (Webster's, at p. 317.) Clearly, a man who summons a lone female stranger to his car to expose his genitals and his masturbatory activity is a person who is engaging in sexual behavior that significantly departs from our societal norms. Gina's testimony also provided substantial support for the prosecutor's assertion that defendant was "a scary guy." After being exposed to defendant's indecency, Gina immediately ran away screaming for help, and she kept running until defendant left the area. A reasonable trier of fact could have concluded that she did so because she found defendant to be "a scary guy."
It follows that the prosecutor's references to defendant as a predator, a sexual deviant, and a scary guy were appropriate epithets, because they were reasonable deductions from the evidence. A reasonable trier of fact could conclude that these were appropriate epithets to describe a person who, in broad daylight, summoned a lone, unsuspecting female stranger to his car so that he could lewdly display to her that he was naked from the waist down and was masturbating.
More importantly, the prosecutor's opportunity to use such epithets in argument cannot be attributed to the joint trial of the indecent exposure and assault counts. The prosecutor could have properly utilized the same epithets based solely on the assault counts. A man who uses a knife to force his way into the car of a lone female stranger in order to perpetrate a sexually motivated attack on her is reasonably characterized as a predator, a sexual deviant, and "a scary guy."
*427 Defendant also contends that the joint trial of the indecent exposure and assault counts permitted him to be unduly prejudiced by the prosecutor's improper argument that the indecent exposure offense showed that defendant had a "motive" to commit the assault and that the indecent exposure and assault offenses had a common modus operandi. "When the issue `focuses on comments made by the prosecutor before the jury, the question is whether there is a reasonable likelihood that the jury construed or applied any of the complained-of remarks in an objectionable fashion.'" (Harrison, supra, 35 Cal.4th at p. 244.)
Defendant views the prosecutor's comments through a narrow lens that tightly focuses on the legal meaning of "motive" and "modus operandi." However, it is not reasonably likely that the jury attached anything other than their common meaning to these terms. In common parlance, "motive" refers to "something (as a need or desire) that causes a person to act." (Webster's, supra, at p. 759.) The jury would have understood the prosecutor's comment about motive to refer to defendant's desire for sexual stimulation. The evidence supported the inference that defendant's base desire for sexual stimulation motivated both the indecent exposure and the assault. The common meaning of "modus operandi" is "a method of procedure." (Webster's, at p. 748.) The jury would have understood the prosecutor's use of the term "modus operandi" to refer to the fact that both the indecent exposure and the assault involved defendant arriving in a vehicle, approaching a female stranger who was alone, seeking nonconsensual sexual stimulation, and then escaping in his vehicle after the female fled and screamed for help. Notwithstanding some notable distinctions between the two events, these similarities could well have suggested to a rational fact finder that defendant utilized a common "method of procedure" on both occasions. While the joint trial of the indecent exposure and assault counts allowed the prosecutor to make such an argument, the cross-admissibility of the indecent exposure evidence would have permitted such an argument even in separate trials.
Defendant has failed to establish that the joint trial of the indecent exposure and assault counts deprived him of a fair trial.

B. Other Contentions

1. Comments on Failure to Produce Alibi Evidence
Defendant also contends that the prosecutor improperly commented on his failure to present alibi evidence.


*428 a. Background
The court instructed the jury: "A defendant in a criminal trial has a constitutional right not to be compelled to testify. You must not draw any inference from the fact the defendant does not testify. Further, you must neither discuss this matter nor permit it to enter into your deliberations in any way." "No lack of testimony on the defendant's part will make up for a failure of proof by the People so as to support a finding against him on any essential elements."
As part of his argument about defendant's "opportunity" to commit the assault on Gloria, the prosecutor argued that defendant had had the opportunity to call any witnesses he wished to call. "Ladies and gentlemen, did we hear an alibi? Did they present any evidence that he didn't have the opportunity to commit these crimes? We didn't hear from any of his friends except the [one] friend, and all he said was he's good in jujitsu. [¶] No friends gave him an alibi. No family gave him an alibi, his girlfriend didn't come to testify that she was with him. He lives with his mom and his brother. They didn't come and testify where he was on the night, the morning. There's no internet record to show he was surfing the internet at any particular time. No gasoline or credit card purchase was presented to show he was in a different area. [¶] There's no evidence presented he was in a competition, maybe he was out of state, maybe he was in a different country. He's such a great grappler, maybe he's going to competition. There's absolutely no evidence of an alibi, ladies and gentlemen. [¶] Now, what does that tell you? It doesn't prove that he's guilty. What it shows, ladies and gentlemen, is that he had the opportunity, because I assure you, if he had an alibi, if they had some corroborating evidence to establish that he wasn't there or didn't have the opportunity to commit this crime, you would have heard that evidence. Since you didn't hear it, you can infer that he did have the opportunity to commit this crime, because there was no evidence that he was someone [sic] else or that he was doing something with someone else or that he was in a different location."
Defendant's trial counsel addressed these comments at the beginning of her closing argument. "[The prosecutor] has flipped the presumption of innocence on its ear. Why didn't Mr. Earle present any evidence? Why didn't he have an alibi? [¶] First of all, it was 5:00 o'clock in the morning, but that's not the point. The point is that he doesn't have to present anything. . . . [¶] . . . [¶] The fact, when you look at this case, you must start with the presumption of innocence. And you can't flip it on it's [sic] ear to say, why didn't Mr. Earle call anyone to say where he was at 5:00 in the morning. That is completely inappropriate and you must start with the presumption of innocence." At this point, the prosecutor objected "to the characterization, that that was inappropriate." The court sustained the objection "as to the argument as to that word, *429 but you may continue." Defendant's trial counsel continued her argument. "The law requires a presumption of innocence. It does not require the defendant to prove anything."
The prosecutor addressed this issue in his closing argument. "Defense said, well, mentioned something about . . . this alibi and suggested I made an improper argument and saying, why didn't they bring in alibi evidence. [¶] Well, the defendant absolutely has the right not to present evidence. He doesn't have to present evidence at all. In fact, he can just rely on the state of the evidence and not present any evidence and say, you know what, the people haven't met their burden. [¶] And in fact when I made that argument about the alibi, how they didn't present evidence of an alibi, he's certainly not required to do it. And if the defense had not presented any evidence at all and just said, hey, you know what, Mr. Baker hasn't proved his case, I wouldn't have made that argument. [¶] But the defense decided to put on evidence. Decided to present a defense. They decided to attack the credibility of my witnesses and my victims. [¶] What better way to attack the credibility of these witnesses and victims than if he had just presented an alibi, but he didn't. He doesn't have to, but he has the constitutional right to do so. [¶] Now, does that in and of itself prove that he's guilty? [¶] No. [¶] Should you convict him because he didn't present evidence of an alibi? [¶] Absolutely not. [¶] And that would be completely wrong. If you went back there and said, hey, you know what, he didn't present evidence of an alibi so therefore he's guilty. No. Absolutely not. [¶] But it's a fact to consider in the totality of the circumstances. It shows that he had an opportunity to commit this crime. We know he had the means. We know he had the motive."
The prosecutor continued to argue this theme. "You cannot speculate as to possible facts. The defense says, well, they're saying we should have presented an alibi. And it's not fair, maybe three, four months after you've got to come in and present an alibi or figure out where you were. [¶] Well, Mr. Earle was arrested just a little over two weeks after this crime occurred. On top of that, the defense said, maybe my guy was alone, was sleeping at home by himself, well, there's no evidence of that. There's no evidence presented like that at all. You can't consider it. You can't consider comments of counsel and you can't consider it unless you heard it on the witness stand or you see it in the exhibits."

b. Analysis
Defendant argues that these comments violated the rule that a prosecutor "may not comment upon a defendant's failure to testify in his or her own behalf." (People v. Bradford (1997) 15 Cal.4th 1229, 1339 [65 Cal.Rptr.2d 145, 939 P.2d 259] (Bradford).) A prosecutor violates this rule "if he or she *430 argues to the jury that certain testimony or evidence is uncontradicted, if such contradiction or denial could be provided only by the defendant, who therefore would be required to take the witness stand." (Bradford, at p. 1339.) No violation occurs if the prosecutor's "comments [are] based upon the state of the evidence or upon the failure of the defense to introduce material evidence or to call anticipated witnesses." (Ibid.)
Defendant's argument is premised on his claim that only he could have provided himself with an alibi for the time of the attack on Gloria because it occurred at 5:00 a.m. Yet the prosecutor's comments themselves highlighted the many other types of evidence that defendant could have produced to support an alibi defense. As the prosecutor pointed out, defendant could have produced a witness other than himself who was aware of his whereabouts at that time, such as a family member or a girlfriend. Or, as the prosecutor also noted, he could have produced documentary evidence that he was in another location at the time of the attack on Gloria. Since such evidence could have come from someone other than defendant, and the prosecutor made this clear, the prosecutor's comments cannot be interpreted as improper comments on defendant's failure to testify rather than proper comments on the defense's failure to produce material evidence.

2. Cross-examination of Eyewitness Identification Expert
Defendant also argues that the prosecutor committed misconduct by improperly cross-examining the defense eyewitness identification expert.

a. Background
The prosecution moved in limine to limit the scope of the testimony of the defense's eyewitness identification expert. This motion sought exclusion under Evidence Code section 352 of "any opinions or testimony by the doctor that relate specifically to the facts of this case," including any "opinion as to the accuracy of the victim's identification" and testimony "about specific facts of this case and how it might have affected the victim's identification." Defendant's trial counsel stated at the in limine hearing that she did not intend to elicit such testimony. The court noted that no such testimony was going to be elicited, and it did not explicitly rule on the prosecution's motion.
Geoffrey Loftus thereafter testified for the defense as an expert on "human perception and human memory." He testified on direct examination that people "can report memories . . . with a great deal of confidence but memories that are just dead wrong in many important respects." Loftus said that "the large majority" of those who have been wrongly convicted of crimes *431 have been convicted on the basis of faulty eyewitness identification testimony. He identified four factors that could render a memory inaccurate. First, the environment at the time of the event, such as a lack of sufficient lighting, may preclude a clear assessment of the details. Events perceived at night under dim illumination may produce memories that lack color and fine detail. Second, the eyewitness may be stressed or otherwise debilitated at the time of the event. For instance, the eyewitness may not pay attention to other details when his or her attention is focused on a weapon. Third, the time between the event and the recollection of the memory may cause the witness to forget things or to reconstruct the memory based on information acquired after the event. Finally, the procedures used to elicit the recollection of the memory may be suggestive and cause distortion of the memory.
After Loftus's extensive testimony on direct examination, the prosecutor began his cross-examination by asking Loftus to "clarify" that he had "no opinion" about whether defendant had committed the alleged crimes. Loftus confirmed as much. The prosecutor also asked Loftus whether he had visited the crime scene or tested the lighting levels there. Loftus confirmed that he had not. The prosecutor later had Loftus confirm that he had not been present during the trial or heard the evidence or seen the exhibits that had been introduced at trial.
Defendant's trial counsel noted in her closing argument that Loftus "wasn't here to decide if the I.D. was accurate. That's your job. [¶] What he was here to do was to provide tools to you so that you can evaluate how to determine the accuracy and the credibility of that identification, that's what he was here to do, to educate, and that's what he did."

b. Analysis
Defendant contends on appeal that the prosecutor "committed misconduct by obtaining an in limine ruling restricting the direct examination of [Loftus], and then improperly exploiting this ruling on cross-examination." This contention lacks merit. The prosecutor did not obtain an in limine ruling restricting Loftus's testimony. Defendant's trial counsel stated at the in limine hearing that she did not intend to offer the type of testimony that the prosecutor sought to bar. Hence, a ruling on the prosecutor's motion was unnecessary. Since the defense never intended to elicit such testimony, there was nothing for the prosecutor to "improperly exploit[]." The prosecutor's brief inquiry asking Loftus to confirm that he was not commenting on the particular facts of this case was entirely properly and was not misconduct.


*432 IV. Conclusion
I would find no abuse of discretion in the trial court's denial of defendant's severance motion, no denial of due process, and no other prejudicial errors. Accordingly, other than requiring the trial court to correct the abstract of judgment to correctly describe the Penal Code section 245, subdivision (a)(1) conviction as "Assault with a deadly weapon" rather than "Indecent exposure," I would affirm the judgment.
NOTES
[1]  Both victims happen to have the same initials. This makes it impossible to discuss the facts intelligibly using initials only. We will therefore refer to the victims by fictitious names. Insofar as an order is required for this purpose, such an order is hereby made.
[2]  She testified that he held a small knife and that after she escaped she discovered a cut on her hand. A photograph in evidence depicted a cut on her outer wrist. This evidence formed the basis for the charge of assault with a deadly weapon. Police found a "small retractable knife" in the living room of defendant's home, which he shared with his mother and brother. That knife tested negative for blood. It was not offered in evidence and was never shown to Gloria.

The prosecutor told jurors that the assailant also used "a small retractable knife," but no evidence supported the second adjective. Gloria only said the assailant had "a little small, like a hand, a hand knife," which was "very narrow." She was unable to say whether it was a "switchblade." Implicitly acknowledging the transparency of his mischaracterization, the prosecutor allowed that "maybe" defendant "used a different knife" than the one found by police, but urged the jurors to still draw an incriminating inference from finding of a knife in his shared home.
[3]  After defendant's arrest, Detective Gutierrez retrieved a black garment from defendant's home through defendant's girlfriend. On questioning by the prosecutor the detective characterized this garment as a "black jacket . . . ." On further defense examination he allowed that it was in fact a "wool blazer . . . ."
[4]  For the ostensible purpose of illustrating the similarity of the two vehicles, the prosecutor introduced three small photographs of defendant's truck and a low-resolution printout of an advertisement for a 1981 Ford Bronco. In argument he told the jury that the vehicles thus depicted bore a striking resemblance to one another: "The lights are similar. Really the only difference, there's a minor difference in the grill and that's a Chevy logo versus a Ford logo." The record does not disclose whether a similar degree of resemblance might have been found between defendant's truck and the model actually described by the witness.
[5]  Gloria testified that upon her truck's emergence from the carwash, the man in the truck "t[ook] off all of the sudden, really fast and dr[o]ve up next to where my truck had come out of the car wash and pull[ed] up right next to it, look[ed] at it and then continue[d] driving." A juror viewing Gloria's testimony critically might view this account with skepticism, since nothing in the record can explain the conduct thus described. At the time of the assault Gloria was driving a four-door sedan, not the Envoy that supposedly triggered this bizarre reaction from the Blazer driver. Her assailant had no apparent reason to take any notice of the Envoy.
[6]  The indecent exposure was originally charged in a separate file and later consolidated with the assault charges. The file of the indecent exposure case prior to consolidation does not appear in the present record.
[7]  The abstract of judgment omits the charge of assault with a deadly weapon, but the omission appears immaterial since the court's minutes reflect an intention to stay sentence on that count pursuant to Penal Code section 654. The abstract of judgment also appears mistaken in stating that the court stayed sentence on the indecent exposure count under that statute. Such a stay would be plain error since the charges arise from entirely distinct events. The court's intention was to impose a six-month term on the indecent exposure to be served concurrently with the assault.
[8]  Because counts 1 and 2 arose from a single instance of conduct, we will often refer to them in the singular as "the assault charge."
[9]  One study showed that 19 percent of exhibitionists reported committing rape, while 15.4 percent of rapists reported engaging in exhibitionism. Another study yielded corresponding figures of 28 percent and 25 percent.
[10]  The prosecutor declined to lodge an objection to the Abbott declaration, expressing confidence at the hearing that the court would "give it whatever weight the court feels is appropriate."
[11]  Our dissenting colleague's analysis of eligibility exemplifies the ongoing judicial struggle to give the statute a coherent meaning and application. The statute's primary criteriathat crimes be "connected together in their commission" or belong to the "same class of . . . offenses" (§ 954)are highly ambiguous. Their unworkability as guides for decision has caused them to be supplanted by judicial glosses that are themselves remarkably vague. (See People v. Kemp (1961) 55 Cal.2d 458, 476 [11 Cal.Rptr. 361, 359 P.2d 913] ["`"`same class of crimes'"'" means "`"offenses possessing common characteristics or attributes"'"]; People v. Matson (1974) 13 Cal.3d 35, 39 [117 Cal.Rptr. 664, 528 P.2d 752] ["`connected together in their commission'" requires a "`common element of substantial importance'"].) The dissent insists that these nebulous formulae describe two distinct tests, but the only apparent difference is that the first is more overbroad than the second, logically subsuming it. Among the statute's other weaknesses is its failure to distinguish between the joinder of multiple charges against a single defendant, as to which the state should obviously enjoy greater latitude, and joinder of charges against multiple defendants, as to which a more restrictive rule seems necessary and appropriate. (Cf. Fed. Rules Crim.Proc., rule 8, 18 U.S.C.)
[12]  Counsel wrote in part, "In the present case, failure to sever the counts against Mr. Earl[e] would be unduly prejudicial. The evidence of the two offenses would not be cross-admissible. The two incidents occurred three months apart and were in no way connected to one another. The case involving indecent exposure occurred during the day and there was no inference of force, violence or a weapon. The second offense alleges a forceful and violent attack with a knife at 5:00 in the morning. There is no physical evidence linking Mr. Earl[e] to this incident. The incidents occur[red] at different locations, different times of the day and involve very different conduct."
[13]  The dissent denies that there was any evidence that the assailant "attempted to touch, [Gloria's] private parts" or "to remove her clothing." (Dis. opn., post, at p. 420.) This may be narrowly true: When Gloria was asked whether the assailant "tr[ied] to take your pants off," her reply was, "No." But she went on immediately to explain, "I don't think he washe had a chance to do any touching, because he was still trying to make me lie down and he was pulling my hair. So that's what he was doing with his hands." She then testified that she could not remember whether he tried to unbutton her pants. Shortly before this she had testified, "I noticed that all of the sudden he seemed to become even more aggressive. I had fairly tight pants on and I also had an apron on over them that was tied[,] [a]nd this seemed to infuriate him even more." The unmistakable purport of this testimony was that if defendant did not succeed in removing her clothing and touching her intimately, it was not for want of trying, but only because she fought off his attempts to subdue her to a point where he could accomplish his obvious goal. No rational juror could have supposed otherwise.
[14]  Although the dissent does not defend the use of the evidence to show identity, it does attempt to convey the impression that the two offenses had small details in common. A good example is its statement that defendant "summoned [Gina] to his car window" whereas the assailant "approached the car window of another lone female stranger," i.e., Gloria. (Dis. opn., post, at p. 420, italics added.) The first statement is an accurate characterization of the testimony. The second is not, though its literal truth may be deduced from Gloria's testimony that the assailant appeared while she was sitting in her open car door. By approaching the car, the assailant perforce approached all of its component parts, including its windows. One might say with equal accuracyand equal pertinencethat he approached the steering wheel or the battery.
[15]  Evidence Code section 1108 would not authorize the admission of expert opinion concerning the presence or absence of a particular disposition in a particular defendant. (People v. McFarland (2000) 78 Cal.App.4th 489, 495 [92 Cal.Rptr.2d 884]; see id. at p. 496, citing Pen. Code, § 29 [expert may not testify on "the ultimate question of whether the defendant had or did not have a particular mental state at the time he committed the offense"].) This does not mean that in a sex crimes prosecution, the state may not be required to lay a proper foundation for an inference of propensity to commit the charged offense. For instance, testimony like Dr. Abbott's, addressing the incidence of rapes by criminal exhibitionists and vice versa, and the factors bearing on the likelihood of an exhibitionist's committing rape, would offend neither of the prohibitions just noted, but would provide the jury with an evidentiary foundation on which to predicate an inference, as well as an estimate of the likelihood, that defendant's commission of indecent exposure actually reflected a propensity to commit rape. It was not defendant's burden to make this showing. It is for the proponent of evidence to establish the foundational facts for its admission, including its relevance to a material issue. (See Evid. Code, § 403, subd. (a).)
[16]  To be sure, nonsexual crimes may also be the product of psychological compulsion. "Kleptophilia" describes a tendency to receive sexual arousal or gratification from theft or burglary. (Dorland's Illustrated Medical Dict. (29th ed. 2000) p. 947.) One who has exhibited this trait might be expected to commit crimes of larceny and burglary in the same way that a criminal exhibitionist might be expected to repeat his offense. Indeed the compulsion need not have sexual origins; it may be driven, as in the case of "kleptomania," by a compulsion or impulse disorder. (See American Psychiatric Assn., Diagnostic and Statistical Manual of Mental Disorders (4th ed. text rev. 2000) p. 667.) Of course, Evidence Code section 1108 would not apply, and this evidence would presumably not be admissible, in a prosecution for theft or burglary.
[17]  The dissent states flatly that defense counsel "conceded in closing argument that defendant was guilty of the indecent exposure count," which conveys the impression that counsel expressly acceded to defendant's guilt. (Dis. opn., post, at p. 416.) She did not. Her relevant comments were as follows: "Now, I want to show briefly about what I believe the evidence has shown in this case as to count three [the indecent exposure]. The evidence is there, I expect you to go back and do your duty and vote appropriately. [¶] According to the evidence with regard to counts one and two, I'm going to submit to you, based on the evidence, Mr. Earle is not guilty. And I'm going to show you why I believe that. [¶] And I wanted to mention again about count three because we heard that count three corroborates counts one and two. And there is no evidence that count three corroborates anything, count three is what it is. And there is no evidence, no nothing to suggest that a person who sits in a car and exposes himselfunsavory though it may beis a person who would attack someone in the middle of the night using a knife. [¶] And I say that because there was no evidence to suggest that. And just because it's convenient to say he did count one and two because he may have done three, convenient, is not what this is about. This is about a process and that's why you're here. [¶] There was some talk about, perhaps, after the exposure he was frustrated and he was lookingthere is no evidence as to that. That's all speculation and you're not allowed to use that." (Italics added.)
[18]  In jury argument the prosecutor sought to minimize this characterization by calling it "the impression of the person who took the booking photo...." But the prosecution itself relied on nothing more than the "impression" formed by an untrained, terrified observer fighting off a nocturnal assault inside a vehicle illuminated only by overhead parking lot lights. This lends considerable irony to the dismissal of the officially recorded "impression" of a (presumably trained) police officer, formed under conditions suitable for photography.
[19]  Curiously, when a police officer was asked how authorities concluded that the driver of the Bronco was not a suspect, he replied only, "I believe we didn't find any photos on this individual so we couldn't conduct any type of lineup." This suggests not that police ruled him out, but that they failed to investigate further, perhaps because of defendant's arrest.
[20]  The dissent makes no attempt to identify any inaccuracy in our account of the prosecution evidence but responds that the jurors rejected defense attacks on that evidence. Of course they did; otherwise they would have acquitted defendant, and the case would not be before us. The question here is whether the record reveals an unacceptable likelihood that they were led to their decision by evidence of the indecent exposure. The only point of any substance made by the defense is that defense counsel conceded a similarity between the police sketch and an older mug shot of defendantnot the mug shot taken after his arrest for the assault, less than three weeks after Gloria supposedly saw him. It is true that the sketch bears some resemblance to defendant as depicted in that mug shot, but it does not impress us as a striking one, and certainly need not have been found striking by a reasonable juror whose reasoning processes had not been poisoned by irrelevant evidence of other sexual misconduct and specious but inflammatory prosecution arguments predicated on that evidence.
[21]  We make nothing of the fact that in a misdemeanor case, as this would have been, the parties are free to agree to a jury of less than 12 persons. (Cal. Const., art. I, § 16.)
[1]  To avoid confusion, I adopt the majority opinion's naming convention. (See maj. opn., ante, at p. 380, fn. 1.)
[2]  There is an error on the abstract of judgment. The Penal Code section 245, subdivision (a)(1) conviction is erroneously described as the crime of "Indecent exposure."
[3]  Defendant did not make this contention below, and the Attorney General contends that it was forfeited. However, defendant claims that his trial counsel was prejudicially deficient in failing to raise this contention below. I would resolve his contention on the merits so that it would not be necessary to consider whether defendant's trial counsel was deficient in failing to raise this claim below.
[4]  I would reject defendant's characterization of the similarity as merely "sexual misconduct." The similarity is far more specific. The two offenses have very similar intent elements.
[5]  "[C]omplete (or so-called two-way) cross-admissibility is not required. In other words, it may be sufficient, for example, if evidence underlying charge `B' is admissible in the trial of charge `A'even though evidence underlying charge `A' may not be similarly admissible in the trial of charge `B.'" (Alcala, supra, 43 Cal.4th at p. 1221.)
[6]  The defense expert's declaration did establish that it was more likely that an exhibitionist, as opposed to a nonexhibitionist, would commit rape.
[7]  Defendant contends that the trial court's ruling was deficient because the court did not explicitly mention cross-admissibility. There is no requirement that a trial court ruling on a severance motion detail its reasoning. The critical question in ruling on a severance motion is whether the defendant has shown a substantial danger of prejudice. The trial court explicitly stated that defendant would not be prejudiced by a joint trial. No further explanation was required.
