Randolph, Circuit Judge:


1
As the rules governing criminal  trials multiply, even the simplest prosecution can generate a  host of legal errors.  We have before us a three-witness case,  charging unlawful possession of a firearm and assault on two  police officers.  Yet there are problems with the indictment,  with the government's failure to disclose evidence to the  accused, with the standard used to assess the effect of this,  and with the sentence.  The case must be remanded, at least  for resentencing, as the government now acknowledges. Among the open questions is whether there must also be a  new trial.


2
* Walter J. Bowie went to trial in March 1998 on a three  count indictment.  The first count charged that, as a convicted felon, he unlawfully possessed a firearm.  See 18 U.S.C.   922(g)(1).  The other counts charged him with assaulting,  resisting, opposing, impeding and interfering with a police  officer "while armed with a deadly or dangerous weapon," in  violation of local law.  Each of these two counts closed with  the same parenthetical:  "(Assaulting, Resisting, or Interfering with a Police Officer While Armed With a Dangerous  Weapon, in violation of Title 22, District of Columbia Code,  Sections 505(b) and 3202(a)(1))".


3
The prosecution and defense stipulated to Bowie's status as  a convicted felon.  The district court denied a motion to  suppress and trial commenced.  The prosecution called Lonnie Moses and Paul Riggins, both police officers, and an  expert witness.  The defense called no one.  Officer Moses testified that he saw Bowie on the street receiving money  from an unidentified man and handing the man something in  return.  He told officer Riggins what he had witnessed.  The  officers approached the men, Moses wearing a vest with the  word "Police" across the front, Riggins in full uniform.  The  unidentified man walked away.  When Moses called out,  Bowie came toward the officers.  As Moses reached for  Bowie's arm, Bowie knocked the officer's hand away and then  shoved him in the chest.  A struggle ensued.  According to  Moses, as he and Riggins were wrestling Bowie to the  ground, trying to handcuff him, Bowie kept reaching into his  waist area.  When they finally subdued him, and stood him  up, Moses pulled up the front of Bowie's shirt and a loaded  .357 magnum--a large pistol--fell out, hitting Moses on the  shin.  Officer Riggins's version of the events tallied with that  of Moses, except that Riggins testified the pistol fell out while  they were still struggling to get Bowie to the ground.  The  government's expert testified that the pistol had been manufactured in Connecticut.  The jury returned a verdict of  guilty on all counts.


4
About a month later, the prosecutor sent a letter to defense  counsel disclosing that Moses was under investigation by the  United States Attorney's Office regarding his testimony in an  unrelated case and that the investigation had begun before  Bowie's trial.  This information had not been revealed before  trial although Bowie's attorney had requested the government to provide all material and information covered by  Brady v. Maryland, 373 U.S. 83 (1963).  Bowie's attorney  responded to the letter with a motion for a new trial.  During  the hearing on the motion, more details emerged about the  investigation of officer Moses.


5
On January 14, 1998--the date will become important-Moses testified in a suppression hearing before the Honorable A. Franklin Burgess of the Superior Court of the District of Columbia, the local trial court.  The case bore the title  United States v. Davon Williams.  When the hearing ended  after two days of testimony, Judge Burgess suppressed the  evidence, finding the defense witnesses more credible than  Moses.


6
As the chief prosecutor in the local and the federal courts,  the United States Attorney for the District of Columbia  maintains a computerized list of police officers who are under  investigation--the "Lewis list," after Lewis v. United States,  408 A.2d 303, 306 (D.C. 1979).  Moses became the subject of  an investigation into the truthfulness of his testimony in the  Williams case on February 27, 1998.  His name was added to  the Lewis list, when exactly is unknown, but the government  concedes it was before the start of Bowie's trial on March 10,  1998.  The prosecutor explained that when she checked the  Lewis list sometime before Bowie's trial, she did not find  Moses's name and that she became aware of his listing only  when Moses called her three days after Bowie's conviction  saying "You may have a problem, you know, I just learned I  have been placed on the Lewis list."


7
At the hearing on Bowie's motion, the prosecutor and the  defense attorney treated the issue, not in terms of the  prosecutor's disclosure duty under Brady, but in terms of  newly-discovered evidence.  The district court did the same,  denying the new trial motion because "(1) it is unlikely that  the newly discovered evidence upon which Mr. Bowie grounds  his motion--Officer Moses' testimony in and the surrounding  circumstances of the Devon Williams case--would be admissible at a new trial;  (2) the new evidence is merely impeaching;(3) the evidence is not of such a nature that in a new trial it  would probably produce an acquittal."  United States v.  Bowie, No. 98-Cr-0008 (D.D.C. Nov. 5, 1998) (order denying  motion for a new trial).

II

8
Now that the case is on appeal, neither the government nor  the defense argues about whether the undisclosed information  constitutes newly discovered evidence.  Both sides acknowledge that Brady and the cases following it provide the  governing legal principles.  These legal principles are as  follows.  The Due Process Clause requires a prosecutor to  disclose, upon request, information favorable to the accused  "that is material to either guilt or to punishment."  Brady, 373 U.S. at 87.  Evidence affecting the credibility of government witnesses is a category of exculpatory information potentially within Brady's disclosure obligation.  See Giglio v.  United States, 405 U.S. 150, 154 (1972).  If the government  failed to disclose exculpatory evidence, a defendant is not  entitled to have his conviction overturned unless the evidence  was "material."  United States v. Bagley, 473 U.S. 667, 67478 (1985);  United States v. Agurs, 427 U.S. 97, 112 (1976).Evidence is "material" only if " 'there is a reasonable probability that, had the evidence been disclosed to the defense, the  result of the proceeding would have been different.' "  Kyles  v. Whitley, 514 U.S. 419, 433-34 (1995) (quoting Bagley, 473  U.S. at 682 (opinion of Blackmun, J.)).  A "reasonable probability" means the chances are high enough to undermine  confidence in the outcome.  See Kyles, 514 U.S. at 434;Strickler v. Greene, 119 S. Ct. 1936, 1952 (1999).


9
It is worth pausing here to examine this standard--"reasonable probability," a standard first suggested by Justice  Blackmun in his opinion for himself and Justice O'Connor in  Bagley, endorsed by three other Justices in Bagley (see 473  U.S. at 685 (White, J., concurring in part)), explained by  Justice Souter in his opinion for the Court in Kyles, reaffirmed last term in Strickler, and criticized by Justice Souter in  his separate opinion in Strickler, see 119 S. Ct. at 1956  (Souter, J., concurring in part and dissenting in part).  What  is a "reasonable probability"?  Probability is often expressed  in terms of percentages, with 100% representing certainty. We know, because the Supreme Court has told us, that a  "reasonable probability" can be less than 50.01%.  In other  words, to reverse a conviction for a Brady violation, it does  not have to be more likely than not that the defendant would  have been acquitted had the evidence been disclosed.  See  Kyles, 514 U.S. at 434. We are also sure that a "reasonable  probability" is somewhat greater than 1%.  How much greater?  Enough, the Supreme Court says, to "undermine confidence in the verdict," id. at 435, which may lead us in a circle: one cannot be confident of the outcome when there is a  "reasonable" probability that it may be wrong, and a "reasonable" probability is one high enough to undermine confidence in the outcome.  Fortunately, we do not need to face the  quandary this poses.  Our confidence in Bowie's conviction is  not shaken by the government's post-trial revelation.


10
The government's nonfeasance is clear enough.  The prosecution had a duty, under Brady, to provide defense counsel  with the evidence about Moses before trial and it failed to  carry out its duty.  This much the government admits.  Its  defense of Bowie's conviction proceeds on another ground-that the undisclosed evidence would not have been admissible,  and hence could not possibly be "material."  The government  is right about the admissibility of the evidence.  Bowie's  counsel could not have introduced evidence from the Davon  Williams suppression hearing, whether in the form of live  witnesses or a transcript.  Moses was only under investigation;  he had not been convicted of perjury.  Rule 608(b) of  the Federal Rules of Evidence states:  "Specific instances of  the conduct of a witness, for the purpose of attacking or  supporting the witness' credibility, other than conviction of a  crime as provided in rule 609, may not be proven by extrinsic  evidence."  See 28 Charles A. Wright & Victor J. Gold,  Federal Practice and Procedure  6117, at 80 (1993).


11
Admissibility of extrinsic evidence is one thing, cross examination of the witness another.  Our opinion in United  States v. Cuffie, 80 F.3d 514, 517 (D.C. Cir. 1996), recognizes  as much.  Thus, to refute Bowie's contention that the undisclosed information was "material" in the Brady sense, it is not  enough to show that the transcript of the Davon Williams  hearing would be inadmissible.  The Brady information potentially would have opened up a line of cross-examination  going to Moses's credibility.  To this, the government responds that there is no guarantee that such questioning would  be allowed;  a trial judge has considerable discretion under  Rule 403 of the evidence rules.  But certainty is not necessary and we believe that, at a minimum, the judge would have  permitted the defense to question Moses about his knowledge  of the United States Attorney's investigation.  See United  States v. Abel, 469 U.S. 45, 51 (1984).  Even if Moses said he  did not know, the trial judge might also have allowed questioning about whether Moses feared that an investigation was in the offing, as well he might have in light of the Davon  Williams proceedings.  Even so, the requisite "reasonable  probability" of Bowie's acquittal scarcely follows.


12
Suppose Moses answered affirmatively when asked questions probing his knowledge or fear of an investigation by the  United States Attorney.  Would this show the officer's bias? Bias can manifest itself in hostility to one side, but it can also  take the form of favoring a litigant.  See United States v.  Schaffer, 183 F.3d 833, 852 (D.C. Cir. 1999).  Bowie's counsel  thinks he could establish bias, because the jury would believe  that the officer shaded his testimony in order to curry favor  with his investigators.  That is one possibility, but not the  only one.  The jury might think instead that Moses, knowing  he was under investigation in another case, would be careful  not to worsen his predicament, would be punctilious this time  around, would not shade the truth in the slightest respect.


13
The question remains--how far could cross-examination go  in destroying Moses's credibility?  And if it were destroyed, how high is the probability the jury would have acquitted the  defendant?  We think not very, even if the questioning proceeded like this:


14
Defense counsel:  Officer Moses, you testified in the Superior Court in the Davon Williams case, did you not?


15
Officer Moses:  Yes.


16
Defense counsel:  That was a suppression hearing in January of this year, a proceeding about a search and seizure you carried out?


17
Officer Moses:  Yes.


18
Defense counsel:  And you swore to tell the truth, the whole truth, and nothing but the truth, just as you did here today?


19
Officer Moses:  Yes.


20
Defense counsel:  Now the Superior Court judge ruled against the government in the Williams matter?


21
Officer Moses:  True.


22
Defense counsel:  The judge ruled that way because he did not believe you?


23
Prosecutor:  Objection.  [Out of the presence of the jury.]  Defendant has not established that Moses was untruthful in the prior case.  All the judge said on this score was that he found the defense witnesses morecredible.  This officer does not know what was in the judge's mind.  The jury in this case is the sole judge of the credibility of the witness.  What a judge in another, totally unrelated proceeding thought about this witness has no bearing on this case.  Putting that information before the jury tends to usurp their fact finding function. More than that, it will--in the terms of Rule 403 of the evidence rules--confuse and mislead them.


24
Defense counsel:  Your honor, this is crucial to our defense.  The judge must have found that Moses lied, otherwise he would have denied the suppression motion. Moses wasn't convicted of perjury, to be sure, but the judge's finding amounts to the same thing.


25
The Court:  Objection sustained. The jury will disregard the question.  [See United States v. Lopez, 944 F.2d33, 38 (1st Cir. 1991) (holding that "the credibility assessment made by the presiding judge at an unrelated trial would have entailed a grave risk that the jury might abrogate its exclusive responsibility to determine the credibility of the testimony given by the officer at appellant's trial");  see also Fed. R. Evid. 608(a) (providing that opinion evidence attacking the credibility of a witness must be limited to character for untruthfulness).]


26
Defense counsel:  Now after the Williams matter end-ed, you were worried that the U.S. Attorney might investigate you for perjuring yourself in that case?


27
Officer Moses:  No, I wasn't worried at all because I told the truth then and I'm telling the truth now.


28
Defense counsel:  Well, the fact is that the United States Attorney is now investigating you for perjury?


29
Officer Moses:  That's news to me.  [The prosecutorin this case told the judge that, in her post-trial conversation with Moses, the officer indicated that he did not know about his name being on the Lewis list until after Bowie's conviction.]


30
Defense counsel:  Let me show you defense exhibit 1,marked for identification.  [A copy of the Lewis list.]Officer Moses do you know what the Lewis list is?


31
Prosecutor:  Objection. [Out of the presence of the jury.]  You honor, the whole purpose of allowing this line of cross-examination is to establish that officer Moses was coloring his testimony for the prosecution, in order to gain favor with our office so that we would drop our investigation of him or exonerate him.  I don't agree with the theory, but if he didn't even know of the investigation, the defense theory collapses anyway.  So defense counsel should not now be allowed to get before the jury the fact that we are conducting an investigation.


32
Defense counsel:  Judge, I need to probe the truthful-ness of this officer's claim that he did not know he was on the list.  He's denied knowing that.  I should not have to accept that response.  The only way I can test his candoris to show him the list and get him to acknowledge that he's on it.  Then the jury can decide for itself whether he's telling the truth.


33
The Court:  I'll sustain the objection.  Those on the list are not normally told they are being investigated.  It would be highly unusual for an officer to know this.  He said he didn't know.  You asked the question and now you must accept the answer.


34
We do not suggest that cross-examination could have proceeded in no other way, but only that this hypothetical  transcript is quite plausible.  (At oral argument, Bowie's  counsel could offer no other line of questioning.)  When the  undisclosed Brady material consists of impeachment evidence, a court seeking to determine the probable impact of  the violation must form some idea about how effectively the  evidence could have been used in cross-examination.  Of  course, it is hard to know what effect such questioning would  have had on the jury's assessment of Moses's truthfulness  and of Bowie's guilt.  In that respect, this case differs markedly from Cuffie, in which the government failed to disclose  that its critical witness--a co-defendant who had pled guilty-had committed perjury in another proceeding.  See 80 F.3d at  517-19.  Here, the most one can say is that Moses was under  investigation for perjury because another judge found opposing witnesses more credible than him.


35
If the cross-examination would have led the jury simply to  discredit Moses's testimony, we still are not convinced that  this would give rise to any significant probability of acquittal. In view of the other evidence against the defendant, the jury  could acquit only if it took the added step of believing that the  truth must be opposite of what Moses had told them.  See  United States v. Zeigler, 994 F.2d 845, 848-49 (D.C. Cir.  1993).  Only then could a thinking jury entertain a reasonable  doubt of Bowie's guilt.  Only then would the jury have before  it two opposite versions of what transpired, one from its  disbelief of Moses (the defendant possessed no pistol and he  did not commit an assault), the other from officer Riggins  (the defendant possessed the pistol and committed the assaults).  The point here is not simply that Riggins's testimony, standing alone, would be sufficient to sustain the conviction. It would be, but "the materiality inquiry is not just a  matter of determining whether, after discounting the inculpatory evidence in light of the undisclosed evidence, the remaining evidence is sufficient to support the jury's conclusions."Strickler, 119 S. Ct. at 1952.  Rather, the point is that officer  Riggins--whose credibility was unimpaired--testified to precisely the same events as Moses and, in all important respects, agreed with him.  True, Moses and Riggins disagreed  on when the gun fell out of Bowie's pants--during the scuffle,  or after they had handcuffed him--but this is of no particular  help to the defense.  Both officers agreed that Bowie possessed the pistol and that he assaulted and impeded them,  which made out Bowie's guilt.


36
How likely is it that the cross-examination of Moses would  have been devastating?  Not very, even if the Perry Mason of  our day were defending Bowie.  Federal Rule of Evidence  801 gave the prosecution a ready means of rehabilitating  Moses on redirect:  a witness's prior consistent statement is not hearsay when it is "offered to rebut an express or implied  charge against the [witness] of recent fabrication or improper  influence or motive...."  The Davon Williams hearing,  which led to Moses winding up on the Lewis list, concluded on  January 14, 1998.  Yet by then Moses had already testified in  a preliminary hearing in this case, on December 19, 1997, and before the grand jury on January 6, 1998.  His testimony on  both of those occasions did not vary in any meaningful way  from his testimony at Bowie's March 1998 trial.  Knowing  this, it is unlikely--too unlikely--that the jury would have  believed that Moses slanted his trial testimony because he  knew of, or feared, an investigation by the U.S. Attorney  regarding his testimony in the Davon Williams case.  And  even if the most effective cross-examination had convinced  the jury that Moses was not to be trusted, the unimpeached  testimony of officer Riggins would remain to bolster Moses  and to convince that, whatever happened in the Superior  Court, here the jury could believe beyond any reasonable  doubt that Bowie possessed the pistol and that he attacked  the two officers.


37
In sum, Bowie has not shown to our satisfaction that if the  evidence wrongfully withheld had been disclosed, there was a  reasonable probability the jury would have acquitted him.  In  coming to this conclusion, we have been mindful of our  responsibility to evaluate the impact of the undisclosed evidence not in isolation, but in light of the rest of the trial  record.  See Agurs, 427 U.S. at 112.


38
Thus far we have confined our discussion to the trial phase  of this case.  Bowie faintly suggests, in a caption in his reply  brief but not in the body, that we ought to consider as well  whether the suppression hearing might have come out the  other way.  (Moses was the government's only witness at the  hearing.)  This is too little too late.  Too little because it is  hardly clear that the Brady line of Supreme Court cases  applies to suppression hearings.  Suppression hearings do not  determine a defendant's guilt or punishment, yet Brady rests  on the idea that due process is violated when the withheld  evidence is "material either to guilt or to punishment," 373  U.S. at 87.  Too late because Bowie raised the question for the first time in his reply brief and then only obliquely.  See  Rollins Environmental Services (NJ) Inc. v. EPA, 937 F.2d  649, 652 n.2 (D.C. Cir. 1991);  Fed. R. App. P. 28(a)(6).  We  therefore will not decide the issue.

III

39
We mentioned in the opening a problem with the indictment.  It is this.  The last two counts charged assault on a  police officer while armed with a deadly weapon and cited  D.C. Code §§ 22-505(b) and 22-3202(a)(1).  Section 22-505(a)  spells out the offense of assaulting or impeding a police  officer, which carries a maximum of five years' imprisonment,  while  22-505(b) enhances the penalty to a maximum of ten  years if the defendant "uses a deadly or dangerous weapon"  in committing the offense.  Bowie had a weapon, but even on  the officer's version of events he did not get around to using  it.  The "while armed" language in the indictment comes from   22-3202(a)(1), a sentencing enhancement provision.  A defendant who commits certain offenses while armed will have  his sentence increased.  The government now concedes that  assault on a police officer is not one of the predicate offenses.


40
Where does this leave us?  The government tells us that  the citation to  22-505(b) was a typographical error, that the  grand jury meant to refer to  22-505(a), that Bowie clearly  was guilty of two violations of this provision, one relating to  officer Moses, the other to officer Riggins.  Furthermore, the  trial judge never instructed the jury that to convict, it must  find that Bowie used his pistol, an instruction  22-505(b)  demanded.  But when it came to sentencing, the judge applied  22-505(b) and meted out a sentence of 31/2 to 10 years'  imprisonment, a sentence not permissible under  22-505(a).


41
Unraveling this tangle yields these consequences.  First,  an error in an indictment's citation "shall not" be a ground for  reversal if the error "did not mislead the defendant to the  defendant's prejudice."  Fed. R. Crim. P. 7(c)(3).  Here, Bowie  suffered no prejudice.  His defense, presented through his  counsel's cross examination of the prosecution witnesses, lost  no force on account of the miscitation.  And even if the grand jury intentionally cited  22-505(b), even if, that is, this was  no mere typographical error, the offense laid out in   22-505(a) was a lesser included offense, for which Bowie  was properly convicted.  Assaulting and impeding a police  officer under subsection (a) is necessarily included within  subsection (b).  The wording of  22-505(b) makes this clear:"Whoever in the commission of any such acts [those described  in subsection (a)] uses a deadly or dangerous weapon shall be  imprisoned not more than 10 years."  The federal rule, like  the District of Columbia rule, is that a "defendant may be  found guilty of an offense necessarily included in the offense  charged," Fed. R. Crim. P. 31(c);  D.C. Super. Ct. R. Crim. P.  31(c).


42
We are never bound to accept the government's confession  of error.  Young v. United States, 315 U.S. 257, 258 (1941)  (citing Parlton v. United States, 75 F.2d 772 (D.C. Cir. 1935));United States v. Pryce, 938 F.2d 1343, 1351-52 (D.C. Cir.  1991) (Randolph, J., concurring).  We do so here for obvious  reasons.  Bowie's sentence on the assault counts will be  vacated and the case remanded for resentencing in accordance with  22-505(a).  In pronouncing a new sentence for  Bowie's local law offenses, the trial judge will not be bound by  federal Sentencing Guidelines.  United States v. Cutchin, 956  F.2d 1216, 1219 (D.C. Cir. 1992).

IV

43
All that remains is Bowie's challenge to his sentence of 120  months' imprisonment on the federal charge.  This he opposes on the basis that the trial judge erred in granting upward  departures for "possession of a firearm," see U.S.S.G.   2K2.1(b)(5), and "official victim," see id.   3A1.2.  As he  sees it, the "official victim" enhancement did not apply because the assault did not "creat[e] a substantial risk of serious  bodily injury."  Id.  The trial judge found, and the evidence  amply supports the finding, that Bowie was attempting to pull  the pistol from his waistband.  His assault therefore certainly  did involve a risk of serious bodily injury.  The "official  victim" adjustment raised Bowie's offense level to 27 (Bowie had two prior felony convictions for crimes of violence),  resulting in a sentencing range of 120 to 150 months.  Because the maximum sentence for felony gun possession is 120  months--the sentence Bowie received--any challenges to additional enhancements are of no moment.  Even so, the trial  judge committed no error in making a "possession of a  firearm" adjustment.  Bowie contends that he did not possess  the gun "in connection" with the assault because he did not  use the gun during the assault.  See id.  2K2.1.  But the  provision refers not simply to use, but to use and possession  of a firearm in connection with another felony offense.  See  id.  Bowie's possession of the weapon emboldened him, or  appeared to, and his reaching for the weapon showed his  intent to use it to facilitate his felony assault on the officers. See United States v. Sturtevant, 62 F.3d 33, 34-35 (1st Cir.  1995).  The connection between the possession of the weapon  and the assault was thus established.


44
Affirmed in part and vacated and remanded in part.
