        Review of the judgment of the Court of Appeals in 54 Kan. App. 2d 742, 406 P.3d 380 (2017).
Appeal from Johnson District Court; SARA WELCH, judge. Opinion filed December 6, 2019. Judgment of
the Court of Appeals affirming the district court is affirmed. Judgment of the district court is affirmed.


        Meryl Carver-Allmond, of Capital Appellate Defender Office, argued the cause and was on the
brief for appellant.


        Kendall S. Kaut, assistant district attorney, argued the cause, and Shawn E. Minihan, assistant
district attorney, Stephen M. Howe, district attorney, and Derek Schmidt, attorney general, were on the
brief for appellee.


The opinion of the court was delivered by


        ROSEN, J.: Driving while intoxicated, Jeremy M. Claerhout caused the death of
another driver in a rear-end collision. He was convicted of reckless driving and second-
degree murder for unintentional but reckless homicide. A divided panel of the Court of
Appeals affirmed the conviction, and this court granted review on all issues for which
review was sought.


        The facts underlying the legal issues in this case are essentially undisputed.


                                                   FACTS


        On the afternoon and evening of January 11, 2015, Claerhout and two friends
visited several bars in Olathe, Kansas. All three men consumed beers and cocktails at
each of the bars, and, based on his own recollections and the testimony of bartenders, it is
estimated that Claerhout consumed approximately five 12-ounce beers, four 24-ounce
beers, one 32-ounce beer, and one or two vodka cocktails that afternoon and evening.

                                                      2
After about an hour at the third bar, the three men got into Claerhout's black Ford F-150
pickup truck and headed back toward a bar they had visited earlier. Claerhout was
driving.


       A short time later, a witness standing outside her place of employment saw a white
car drive by; a few seconds later she saw a black Ford truck go by at a high rate of speed,
its engine revving and the tires spraying water in the rain. Ten to 15 seconds afterwards,
she heard a loud impact sound, which prompted her to call 911. Another witness, who
was stopped at an intersection, saw a white Mazda propelled past the intersection at
approximately 90 miles per hour out onto the right side of the grassy shoulder, hit and
break a cable pole, proceed at least another 100 yards, and come to a stop upon colliding
with an iron fence on the other side of the street. She saw a black pickup truck
approaching from behind and at the same speed as the Mazda; it then slowed to a stop.
She also called 911.


       Police and paramedics found the Mazda smashed into a wrought iron fence. The
driver was wearing his seatbelt, and the airbags had deployed. The driver's seat was
broken off its track and had slid backwards, and the driver was unconscious, on the
dashboard and facing the roof.


       The front of the truck was damaged, and a piece from the rear end of the Mazda
was stuck in the front end of the truck. The three occupants of the truck all told police
that they did not know what had happened. Claerhout had bloodshot, watery eyes and the
odor of alcohol on his breath, and he was slurring his words. He was smoking a freshly lit
cigarette, which officers asked him to extinguish. He put out the cigarette but then lit
another one and continued to smoke it after being asked to put it out. He said he had no
idea what happened. Police performed walk-and-turn and one-leg-stand field sobriety
                                              3
tests on him, which he failed. He was arrested and taken to a police station, where an
Intoxilyzer 8000 breath test was administered at 11:30 that night. The breath sample
indicated a blood alcohol content of .211, more than twice the legal limit of .08.


       The accident took place in a mixed residential and office area where the speed
limit was 40 miles per hour. Based on tracks on the grass and the roadway as well as
damage to objects along the way, Officer John Moncayo reconstructed what happened
before and after the collision. There was no braking by either vehicle before the collision.
The truck struck the Mazda at a slight angle on the rear passenger side, propelling the
Mazda onto the grass, where it struck and sheared off a medium-sized tree at its base. The
car continued forward and struck a utility pole, breaking it in half and leaving the top half
of the pole suspended by the cable line. The car then swerved back onto the road, crossed
the center line, struck the curb, went over a small hill, and stopped when it struck a
wrought iron fence. In all, the Mazda traveled some 848 feet after the impact.


       The driver, Christopher Willdermood, was taken to a nearby hospital, where
imaging showed significant bleeding in the back of his brain. He was declared brain-dead
on February 14, 2015. Blood analyses showed no signs of narcotics or alcohol in his
body. The cause of death was listed as complications from a blunt injury to the head.


       The State charged Claerhout with second-degree murder for unintentional but
reckless homicide or, in the alternative, involuntary manslaughter while driving under the
influence of alcohol, and an additional count of reckless driving. The defense theory at
trial was that Claerhout was highly intoxicated and incapable of safely driving at the time
of the accident, and he therefore was guilty of involuntary manslaughter but not guilty of
second-degree murder.


                                              4
       The jury entered a verdict of guilty on the count of second-degree murder, guilty
on the count of involuntary manslaughter while driving under the influence of alcohol,
and guilty of the count of reckless driving. Because the jury found Claerhout guilty of
both alternative homicide charges, the trial court vacated the conviction on the count of
involuntary manslaughter while driving under the influence. The court sentenced him to a
standard term of 117 months for second-degree murder and a concurrent 30-day sentence
for reckless driving.


       A panel of the Court of Appeals affirmed the conviction, with one judge
dissenting. State v. Claerhout, 54 Kan. App. 2d 742, 406 P.3d 380 (2017) This court
granted review on all issues raised in the petition for review.


                                         ANALYSIS


Evidence of Prior Diversion Agreement


       In 2010, Claerhout entered into a diversion agreement subsequent to an arrest for
driving while intoxicated. According to the statements of counsel at a motion to suppress,
the arrest was made after a stop for a missing tail light; there was no indication of
dangerous driving and no accident was involved. At trial, the State was allowed to
introduce the diversion agreement, without explanation, for the purpose under K.S.A.
2016 Supp. 60-455(b) of proving knowledge that driving while intoxicated is dangerous.
Claerhout argues that this evidence should not have been introduced at all, and the
manner in which it was introduced defeated the statutory basis for admitting it.


       K.S.A. 2018 Supp. 60-455(a) makes evidence of a prior crime or civil wrong
inadmissible for the purpose of proving a disposition to commit such an act on another
                                              5
occasion. K.S.A. 2018 Supp. 60-455(b) allows such evidence of a prior crime or civil
wrong when it is "relevant to prove some other material fact including motive,
opportunity, intent, preparation, plan, knowledge, identity or absence of mistake or
accident."


       When the State seeks to introduce evidence of prior bad conduct under K.S.A. 60-
455, that evidence must be material, and its probative value must outweigh its potential
for producing undue prejudice. State v. Gunby, 282 Kan. 39, 48, 144 P.3d 647 (2006).
Whether such evidence is material—meaning that the evidence has some real bearing on
the decision in the case—is reviewed independently, without deference to the district
court. Whether the evidence is relevant to prove a disputed material fact is reviewed only
for abuse of discretion. Whether the probative value of the evidence outweighs the
potential for undue prejudice against the defendant is also reviewed only for abuse of
discretion. State v. Haygood, 308 Kan. 1387, 1392-93, 430 P.3d 11 (2018).


       A district court abuses its discretion when: (1) no reasonable person would take
the view adopted by the judge; (2) a ruling is based on an error of law; or (3) substantial
competent evidence does not support a finding of fact on which the exercise of discretion
is based. State v. Boysaw, 309 Kan. 526, 539, 439 P.3d 909 (2019).


       The jury found Claerhout guilty of both reckless second-degree murder and
involuntary manslaughter. Claerhout contends the diversion agreement was improperly
introduced in order to prove recklessness and, without it, the jury might have convicted
him of only the involuntary manslaughter charge.


       K.S.A. 2018 Supp. 21-5403(a)(2) defines reckless second-degree murder as the
killing of a human being committed "unintentionally but recklessly under circumstances
                                             6
manifesting extreme indifference to the value of human life." This crime is a severity
level 2 person felony. K.S.A. 2018 Supp. 21-5403(b)(2).


       Advocating outside the presence of the jury for admitting the diversion agreement,
the prosecutor stated the purpose of the diversion evidence was to prove to the jury that
Claerhout had been educated to the reality that driving while intoxicated was dangerous
and his decision to drive while intoxicated was therefore reckless.


       The court agreed with the State's basis for admitting the evidence, stating that the
diversion agreement would demonstrate that Claerhout "should be on notice as to what
the problems of drinking and driving are based upon his prior experience." The Court of
Appeals agreed, holding that the diversion agreement was relevant to show Claerhout's
heightened knowledge of the risks of driving under the influence. 54 Kan. App. 2d at
750-51.


       The Tenth Circuit Court of Appeals has considered a similar question and agreed
that evidence of prior drunk driving is admissible as tending to show knowledge of the
dangers of driving while intoxicated:


               "A jury could infer from Defendant's prior drunk driving convictions that he is
       especially aware of the problems and risks associated with drunk driving. We agree that
       '[o]ne who drives a vehicle while under the influence after having been convicted of that
       offense knows better than most that his conduct is not only illegal, but entails a
       substantial risk of harm to himself and others.'" United States v. Tan, 254 F.3d 1204,
       1210 (10th Cir. 2001) (quoting People v. Brogna, 202 Cal. App. 3d 700, 709, 248 Cal.
       Rptr. 761 (1988).




                                                    7
       Many courts have cited to Tan as support for admitting evidence of prior
convictions for driving while intoxicated. See, e.g., United States v. New, 491 F.3d 369,
374-75 (8th Cir. 2007) (while evidence of prior crimes is not admissible to prove bad
character or propensity to commit bad acts, it may be admissible to prove requisite
knowledge); United States v. Norris, 649 F. Supp. 2d 968, 969-70 (D. Ariz. 2009)
(evidence showing defendant previously convicted of driving under the influence
admissible to prove malice), United States v. Miller, No. 13-CR-1867 WJ, 2014 WL
12796762 (D. N. Mex. 2014) (unpublished opinion); State v. St. Clair, 101 Haw. 280,
288, 67 P.3d 779 (2003) (evidence showing defendant involved in automobile accident
while driving intoxicated less than four years before charged accident involving
pedestrian death was relevant in manslaughter prosecution to prove defendant acted
recklessly when driving after consuming at least 12 beers); Commonwealth v. Diehl, 2016
Pa. Super. 93, 140 A.3d 34, 40 (2016) (evidence of defendant's prior DUI convictions and
alcohol awareness classes was admissible to establish mens rea in vehicular homicide
case premised on DUI accident). See also United States v. Loera, 923 F.2d 725, 729 (9th
Cir. 1991) (prior convictions admitted to prove malice); United States v. Fleming, 739
F.2d 945, 949 (4th Cir. 1984) ("[T]he driving record was relevant to establish that
defendant had grounds to be aware of the risk his drinking and driving while intoxicated
presented to others.").


       We agree with our Court of Appeals and with courts in other jurisdictions. And
while a diversion for driving under the influence is not a conviction, the statutory
requirements and specific details outlined in the agreement essentially serve the same
purpose in showing its relevance. (See generally K.S.A. 2018 Supp. 8-1567[i][1] and
[i][6].) Even if it was never demonstrated what the content of the required instruction
mandated by the diversion agreement was, or even whether he actually attended the
educational programs, by agreeing to and signing the agreement Claerhout acknowledged
                                             8
an understanding that driving while intoxicated is a dangerous and illegal activity. The
jury reasonably could have concluded from the diversion agreement that Claerhout was
on notice that driving while intoxicated is risky behavior, and his decision to engage in
that behavior demonstrated reckless conduct.


       This is not the end of the analysis, however. Claerhout argues that, even if the
diversion agreement had some probative value, that value was outweighed by its
prejudicial effect.


       This court has established safeguards limiting the introduction of K.S.A. 60-455
evidence: The material fact that the evidence is introduced to prove must be disputed,
and the probative value of the evidence must outweigh its potential for producing undue
prejudice. Boysaw, 309 Kan. at 539.


       The district court in the present case conducted a generalized, superficial weighing
of the probative value of the evidence against the potential for undue prejudice, making
the conclusory determination that "the probative value of the evidence outweighs its
prejudicial effect."


       Recognizing the risks that inhere in admitting evidence of other crimes or previous
bad conduct, we recently articulated an analytic framework for district courts to apply
before exposing jurors to such potentially prejudicial evidence:


               "In evaluating the probative value of evidence of other crimes or civil wrongs,
       the district court should consider, among other factors: how clearly the prior act was
       proved; how probative the evidence is of the material fact sought to be proved; how
       seriously disputed the material fact is; and whether the government can obtain any less

                                                   9
       prejudicial evidence. In evaluating the possible prejudicial effect of evidence of other
       crimes or civil wrongs, the district court should consider, among other factors: the
       likelihood that such evidence will contribute to an improperly based jury verdict; the
       extent to which such evidence may distract the jury from the central issues of the trial;
       and how time consuming it will be to prove the prior conduct." Boysaw, 309 Kan. at 541.


       In the present case, the district court's stated reasoning was so abbreviated that we
cannot determine what factors, if any, it considered in reaching its conclusion that the
probative value outweighed the potential prejudicial effect. To be sure, the Boysaw
factors are not exclusive or all-encompassing, but the district court skirted carrying out its
duty to protect a defendant from undue prejudice.


       We need not at this time decide how little or how much analysis a district court
must display to satisfy the Boysaw due process mandates. Reversible error does not
necessarily result in failing to weigh various factors on the record. We have recognized
an implicit determination by a district court that the probative value of K.S.A. 60-455
evidence outweighs the risk of undue prejudice when the court stated that it had reviewed
other caselaw for guidance in carrying out such a weighing procedure. State v. Remmert,
298 Kan. 621, 628, 316 P.3d 154 (2014), disapproved on other grounds by State v. Jolly,
301 Kan. 313, 342 P.3d 935 (2015). Although the district court in the present case did not
state on the record as much analysis as did the Remmert district court, we hold that any
deficiency in the analysis was harmless.


       Admission of evidence under K.S.A. 60-455 is subject to harmless error analysis.
See, e.g., Gunby, 282 Kan. at 59. Here, the evidence was introduced for the stated
purpose of tending to show that Claerhout was aware that driving while intoxicated is
dangerous. Claerhout contends that the risk of prejudice is that the jury might instead

                                                    10
view the diversion agreement as evidence that he had a propensity to drive while
intoxicated, thus suggesting that, even in the absence of evidence of actual intoxication in
the present case, the jury would assume he was intoxicated or punish him for his prior
offense.


       That risk of undue prejudice is minimal here. The evidence that he was intoxicated
was substantial and uncontroverted; Claerhout conceded intoxication in his opening and
closing arguments. He further conceded that he was driving at a speed far in excess of the
legal limit and that his driving caused the death of the victim.


       Furthermore, the district court gave the jury a limiting instruction:


               "Evidence has been admitted tending to show that the defendant committed a
       crime other than the present crime charged. This evidence may be considered solely for
       the purpose of determining whether or not the defendant acted with extreme indifference
       to the value of human life as alleged in Count I."


       This limiting instruction is required as a prophylactic to guard against the danger
that the jury will view K.S.A. 60-455 evidence as tending to show propensity. See
Gunby, 282 Kan. 39, Syl. ¶ 3; State v. Wilkerson, 278 Kan. 147, 153, 91 P.3d 1181
(2004). If such an instruction did not provide some protection against the harm of which
Claerhout complains, it would be nothing more than a superfluous requirement.


       We continue to encourage district courts to state on the record the factors
considered in weighing the admissibility of K.S.A. 60-455 evidence. We disagree with
the Court of Appeals panel majority when it stated that the district court was not required
to explicitly weigh factors used in determining that the probative value of the evidence

                                                   11
outweighed its prejudicial effect because the same risk that the jury would be inclined to
view the diversion agreement as propensity evidence arises every time K.S.A. 60-455
evidence is admitted. Claerhout, 54 Kan. App. 2d at 754. Not all evidence is equally
prejudicial, just as not all evidence is equally probative. We nevertheless find any
deficiencies in the district court's reasoning to be harmless.


Police Officer's Testimony About Vehicle Speeds


       Over Claerhout's pretrial motion to exclude and over a continuing objection at
trial, Officer Matt Misemer testified to crash data retrieval reports he generated from data
stored in both the truck's and the car's airbag control modules. Misemer testified about his
training in investigation and reconstruction, including the ability to analyze crash data
retrieval download information. He concluded with an evaluation of the relative speeds of
the two vehicles at the time of the collision. Claerhout argues on appeal that Misemer was
not qualified to testify about scientific and mathematical conclusions.


       The admission of expert testimony lies within the discretion of the district court
and will not be reversed without a showing that the court abused its discretion. State v.
Graham, 246 Kan. 78, 81, 785 P.2d 983 (1990).


       Misemer testified about the relative speeds of the two vehicles at the time of the
collision. He testified that the airbag control module records such information as vehicle
speed, braking, throttle, and engine rotation and retains that information for five seconds.
He explained that he used software that connected to the modules and that translated the
raw data into usable information, such as vehicle speed.



                                              12
           His report on the data processing results showed that the truck was moving 86
miles per hour five seconds before impact and had accelerated to 92 miles per hour at the
time of impact. The results showed that the truck was being driven at full throttle during
that time; it could not accelerate any faster. Both the module data and the absence of skid
marks showed that the brakes of the truck were not applied during the five seconds before
contact.


           Misemer next testified about the results downloaded from the Mazda. The data
contained information about the five seconds before the car struck the tree, triggering the
airbag. Earlier information, specifically at the moment of impact with the truck, was not
preserved within the five-second loop. Five seconds before the car struck the tree, it was
traveling 62 miles per hour, and it slowed to 47 miles per hour by the time of impact with
the tree. Misemer entered this information, along with the data from the truck and the
weight of the respective vehicles, into a formula to calculate the speed of the Mazda
when the truck ran into it. He calculated that the Mazda was traveling at 47 miles per
hour, plus or minus five percent, at the moment of the collision with the truck.


           Claerhout did not cross-examine Misemer, and he offered no evidence to rebut
Misemer's testimony.


           K.S.A. 2018 Supp. 60-456(b) governs whether an expert witness is qualified to
testify:


                   "If scientific, technical or other specialized knowledge will help the trier of fact
           to understand the evidence or to determine a fact in issue, a witness who is qualified as an
           expert by knowledge, skill, experience, training or education may testify thereto in the
           form of an opinion or otherwise if: (1) The testimony is based on sufficient facts or data;

                                                        13
       (2) the testimony is the product of reliable principles and methods; and (3) the witness
       has reliably applied the principles and methods to the facts of the case."


       Claerhout challenges Misemer's expertise to testify about the scientific basis for
reaching his conclusions about the velocities and acceleration or deceleration rates of the
vehicles. Misemer conceded at a motion to suppress hearing that he did not understand
the laws of physics on which the software platforms were based. On the other hand,
Misemer presented considerable evidence that he was experienced and qualified to utilize
the software and to understand the data that it provided him.


       Claerhout would have this court adopt a requirement that experts be able to
demonstrate their expertise from the ground up. For example, Claerhout challenged
Misemer to show that he would be able to teach a college physics class and explain the
difference between Newtonian and Einsteinian laws governing mass and momentum.


       Claerhout's challenge would seem to require that an expert who presents testimony
on what he or she has seen through a microscope must also be able to explain the optical
qualities of microscopes, or that an expert on reading radiograms should be able to
explain the high-energy physics of x-ray generation. We disagree that expertise in an area
must extend to the theories and principles underlying the discipline that is the subject of
the expert's testimony.


       This court has not previously ruled on the degree to which an expert must be able
to demonstrate knowledge of the principles underlying the expert's expertise. The statute
states with simple clarity that "knowledge, skill, experience, training or education" are the
prerequisite qualifications for serving as an expert witness. The statute does not require
that training or experience must be so thorough that the expert understands the physics or
                                                    14
chemistry underlying the training or experience. As one federal district court stated: "We
do not practice science in court and we do not insist that our expert witnesses do either."
Mercado v. Ahmed, 756 F. Supp. 1097, 1101 (N.D. Ill. 1991).


       Discussing a statute similar to our Kansas rule for admitting expert witnesses, the
Georgia Court of Appeals explained:


       "The requirements for qualification as an expert witness are minimal; generally, nothing
       more is required to qualify an expert than evidence that the person has been educated in a
       particular trade, science, or profession. Formal education or training in an area of
       expertise is not necessary, provided the witness possesses the qualifications of such area
       of expertise through skill and experience. It is the possession of special knowledge
       derived either from experience, study, or both in a field of expertise that makes one an
       'expert.' [Citations omitted.]" In the Interest of C.W.D., 232 Ga. App. 200, 206, 501
       S.E.2d 232 (1998).


       Misemer testified to his training, proficiency testing, and extensive experience in
accident reconstruction and using crash data retrieval. He demonstrated a special
knowledge that would be helpful to the trier of facts. This background sufficed to meet
the statutory requirements for qualification as an expert witness.


       Claerhout did not challenge the reliability of the hardware in the vehicles at
measuring data or of the software used in processing the data. The results to which
Misemer testified were consistent with other evidence admitted at trial. Eyewitness
Megan Kliethermes testified she thought Claerhout was driving 90 miles per hour just
before the collision and the victim was not driving that fast. Eyewitness Hilda Avila
testified that there was nothing unusual or contributory in the manner the victim was
driving; his car drove past her "like any other vehicle would drive by." Misemer's

analysis of the electronic data provided simply confirmed the visual impressions of those
witnesses.


         We find nothing in the record that undermines either Misemer's expertise in
reading crash data retrieval or the reliability of his testimony. Accordingly, we find no
error.


Voluntary Intoxication Instruction


         Claerhout sought to assert a voluntary intoxication defense against the charge of
reckless second-degree murder, contending that his intoxication rendered it impossible
for him to have a reckless state of mind. The district court denied his requested
instruction, and the Court of Appeals affirmed. 54 Kan. App. 2d at 762-63. He argues that
the defense refutes the element of a reckless state of mind.


         This court follows a four-step progression when reviewing challenges to jury
instructions: First, it considers the reviewability of the issue from both jurisdiction and
preservation viewpoints, exercising an unlimited standard of review; next, it applies
unlimited review to determine whether the instruction was legally appropriate; then, it
determines whether there was sufficient evidence, viewed in the light most favorable to
the defendant or the requesting party, that would have supported the instruction; and
finally, if the district court erred, this court determines whether the error was harmless,
utilizing the test and degree of certainty set forth in State v. Ward, 292 Kan. 541, 256
P.3d 801 (2011), cert. denied 565 U.S. 1221 (2012). State v. Murrin, 309 Kan. 385, 391,
435 P.3d 1126 (2019).



                                              16
       We limit our analysis here to the question of whether, under the uncontested facts
of this case, the requested instruction was factually appropriate. Generally, a defendant is
entitled to instructions on the law applicable to his or her defense theory if the evidence
suffices for a rational factfinder to find for the defendant on that theory. If that defendant
requests an instruction at trial, the court must view the evidence in the light most
favorable to the defendant. This court examines jury instructions as a whole, without
focusing on any single instruction, to determine whether they properly and fairly state the
applicable law or whether it is reasonable to conclude that they could have misled the
jury. Murrin, 309 Kan. at 391-92.


       It is counterintuitive to posit that an individual can be so drunk that he or she is
incapable of engaging in reckless conduct. The statutory definition of reckless second-
degree murder involves a killing committed "unintentionally but recklessly under
circumstances manifesting extreme indifference to the value of human life." (Emphasis
added.) K.S.A. 2018 Supp. 21-5403(a)(2). The qualifying words suggest an objective
element of the crime: the circumstances show whether the behavior was reckless. If the
circumstances manifest extreme indifference to the value of human life, the offense was
committed recklessly.


       The uncontested evidence showed that Claerhout got into his truck, started it,
drove down a roadway, decided to accelerate to 90 miles per hour, conversed with the
two passengers, stopped his truck when he realized that he had hit something, and lit and
smoked cigarettes when interviewed by police. We conclude that the mental capability to
engage in and carry out those activities demonstrated the minimal sufficient mental
capacity to engage in reckless conduct. Had he been so extremely intoxicated that he lost
the capacity to consciously disregard a risk of harming others, he also would have lost the
capacity to consciously operate a vehicle in this fashion and converse with others.
                                              17
       In Murrin, this court quoted from LaFave on Substantive Criminal Law. 309 Kan.
at 394. LaFave suggests that the degree of consciousness required for recklessness is
quite low, perhaps even as low as the degree of consciousness required to put a key in a
truck's ignition:


       "'Recklessness' in causing a result exists when one is aware that his conduct might cause
       the result, though it is not substantially certain to happen. One may act recklessly if he
       drives fast through a thickly settled district though his chances of hitting anyone are far
       less than 90%, or even 50%. Indeed, if there is no social utility in doing what he is doing,
       one might be reckless though the chances of harm are something less than 1%. Thus,
       while 'knowledge' and the knowing-type of 'intention' require a consciousness of almost-
       certainly, recklessness requires a consciousness of something far less than certainty or
       even probability." 1 LaFave, Substantive Criminal Law §5.4(f) (3d ed. 2018).


Another treatise explains that courts have historically declined to give a voluntary
intoxication instruction for crimes based on recklessness:


               "The mental state of 'recklessness' ordinarily requires that the defendant be aware
       of and disregard a substantial risk that a particular harm will occur. If the crime charged
       requires recklessness, intoxication is ordinarily not a defense. The intoxication may be so
       extreme as to prevent the defendant from being aware of the pertinent risk. Nevertheless,
       it is commonly provided that if the defendant, as a result of voluntary intoxication, is
       unaware of a risk of which he would have been aware had he been sober, such
       unawareness is immaterial. The supportive theory is that there is enough 'recklessness'
       involved in voluntarily becoming grossly intoxicated—given the general understanding
       in our culture that extreme intoxication lessens inhibitions, provides an outlet for
       aggressive tendencies, and blunts perception and judgment—to warrant criminal
       liability." 2 Wharton's Criminal Law §111 (15th ed. 2019).


                                                    18
       Consistent with Wharton's view, courts have allowed the prosecution to introduce
evidence of voluntary intoxication to prove recklessness, which is the contrary of
Claerhout's position that intoxication should be considered a defense to recklessness.
State v. Jones, 283 Kan. 186, 209, 151 P.3d 22 (2007) (evidence of voluntary intoxication
alone is not enough to warrant instruction on reckless second-degree murder),
disapproved on other grounds by State v. Nelson, 291 Kan. 475, 243 P.3d 343 (2010);
State v. Drennan, 278 Kan. 704, 715, 101 P.3d 1218 (2004) (intoxication can eliminate
intent to kill but may not supply by itself extreme recklessness element of unintentional
second-degree murder); see also People v. Miller, 75 Ill. App. 3d 775, 777-78, 394
N.E.2d 783 (1979) (evidence of intoxication is admissible to prove recklessness in
prosecution for reckless homicide); Commonwealth v. Cobb, 399 Mass. 191, 503 N.E.2d
945 (1987) (reduction of conviction to manslaughter not abuse of discretion when
evidence suffice to support finding that, due to intoxication, defendant acted in reckless
fashion); People v. Colonna, 147 A.D.2d 582, 537 N.Y.S.2d 877 (1989) (defendant
contended he could not have acted recklessly in killing victim; court disagreed, holding
voluntary intoxication does not negate element of recklessness necessary to sustain
conviction of second-degree manslaughter); People v. Vasquez, 104 A.D.2d 429, 478
N.Y.S.2d 947 (1984) (evidence that defendant was drunk during incident would have
supported finding that defendant acted recklessly and not intentionally; trial court should
have instructed on lesser included offense of reckless manslaughter).


       The common thread in all of these cases is that evidence of intoxication was
treated by the courts as evidence of recklessness. We disagree with Claerhout's theory
that evidence of his intoxication tends to show he could not attain a reckless state of mind
because of his impaired mental function.




                                             19
       Because we determine that the requested voluntary intoxication instruction was
not factually appropriate, we need not determine whether it could have been legally
appropriate. The district court did not err in refusing the requested instruction.


       We conclude that no error infected the district court rulings on the three issues that
Claerhout raised in his petition for review. We affirm the judgments of the Court of
Appeals and the district court.
