(dissenting):
I respectfully dissent.
First, I disagree with the strict standard of materiality the majority promulgates for determining whether the prosecution’s nondisclosure of “purely impeaching” evidence requires a new trial. Second, I cannot agree that a police report, in which the victim and sole eyewitness of the crime describes the robber who beat him in terms drastically inconsistent with his testimony at trial, is “purely impeaching” evidence. Finally, I believe that under the proper materiality standard, the petitioner in this case is entitled to relief.
I.
In United States v. Agurs, 1976,-U.S. -, 96 S.Ct. 2392, 49 L.Ed.2d 342, the *1275Supreme Court set forth the standard of materiality that triggers a prosecutor’s duty to disclose voluntarily exculpatory evidence to the defense. The Court held that such disclosure is required when the “evidence creates a reasonable doubt that did not otherwise exist.”--U.S. -, 96 S.Ct. at 2401, 49 L.Ed.2d at 355. In formulating this standard, the Court explicitly rejected the notion that the harsh materiality standard applied in evaluating motions for new trial under Fed.R.Crim.P. 33 — the standard which the majority today adopts with respect to prosecutorial nondisclosure of impeaching evidence — should be applied to exculpatory evidence within the prosecution’s control.
[T]he fact that such evidence was available to the prosecutor and not submitted to the defense places it in a different category than if it had simply been discovered by a neutral source after trial. For that reason the defendant should not have to satisfy the severe burden of demonstrating that newly discovered evidence probably would have resulted in acquittal. If the standard applied to the usual motion for a new trial based on newly discovered evidence were the same when the evidence was in the State’s possession as when it was found in a neutral source, there would be no special significance to the prosecutor’s obligation to serve the cause of justice.
-U.S.-, 96 S.Ct. at 2401, 49 L.Ed. at 354 (footnote omitted).
Although the Court in Agurs spoke only to the nondisclosure of exculpatory evidence, the above reasoning loses none of its cogency when applied to the nondisclosure of impeaching evidence. In its decisions dealing with the prosecution’s duty with respect to evidence favorable to the defense, the Supreme Court has repeatedly recognized that critical impeachment evidence may play as large a role in determining the outcome of a trial as exculpatory evidence. Giglio v. United States, 1972, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104; Giles v. Maryland, 1967, 386 U.S. 66, 87 S.Ct. 793, 17 L.Ed.2d 737; Napue v. Illinois, 1959, 360 U.S. 264, 79 S.Ct. 1173, 3 L.Ed.2d 1217. See Note, Materiality and Defense Requests: Aids in Defining the Prosecutor’s Duty of Disclosure, 59 Iowa L.Rev. 432, 438 (1973). In Giglio, a promise of immunity to the government’s key witness was not disclosed at trial. Even though the Assistant United States Attorney trying the case was unaware of the promise, the Court reversed the defendant’s conviction. The Court observed:
Brady v. Maryland . held that suppression of material evidence justifies a new trial ‘irrespective of the good faith or bad faith of the prosecution.’ . . . When the ‘reliability of a given witness may well be determinative of guilt or innocence,’ nondisclosure of evidence affecting credibility falls within this general rule.
405 U.S. at 153-154, 92 S.Ct. at 766, 31 L.Ed.2d at 108.1
*1276The majority reasons, in essence, that a stricter standard of materiality is warranted for the disclosure of impeaching evidence because such evidence, in “the search for truth”, does not have probative value equal to that of substantive evidence. Although this is generally true, such logic misses the mark. Application of the same materiality standard to both impeaching and exculpatory evidence does not mean that these two types of evidence would be given equal weight in determining whether prosecutorial nondisclosure requires a new trial. Because impeachment evidence is less likely to give rise to a reasonable doubt than exculpatory evidence, its nondisclosure would serve as the basis for a new trial less frequently than the nondisclosure of exculpatory evidence even if the Agurs standard were applied to both types of evidence. Our focus should be on the impact of the undisclosed evidence on the state’s case against the defendant, not on the type of evidence that the prosecution failed to release.
It is therefore unnecessary and unwise to impose a harsher standard of materiality on impeaching evidence than the Supreme Court applied to exculpatory evidence in Agurs. The Agurs standard is itself a strict one. I cannot acquiesce in the majority’s view that due process is not violated where the prosecution fails to disclose evidence within its control2 that “creates a reasonable doubt that did not otherwise exist” simply because the evidence is deemed “impeaching” rather than “exculpatory”. The severity of the majority’s materiality standard is demonstrated by the denial of relief here; the elusive nature of the distinction between impeaching and exculpatory evidence, upon which this stricter standard is premised, is also illustrated by the facts in this case.
II.
On December 2, 1967, two men robbed James H. Pfister, a real estate rental agent, while he was working in his company’s office in New Orleans. One of the robbers severely beat Pfister with a shovel. In a police report made immediately following the crime, Pfister described the robber who beat him as 6' 1" tall and of slender build. This description is glaringly inconsistent with Pfister’s trial testimony that Garrison, who is 5' 5" tall and stocky in build, was the robber who administered the beating. It was largely, if not solely, on the basis of Pfister’s positive identification of Garrison at trial that Garrison was convicted of armed robbery and sentenced to 99 years in prison.3
The majority characterizes the discrepancy in Pfister’s descriptions of his assailant as “purely impeaching evidence”. I find this characterization untenable, given that Garrison’s sole defense was an alibi. At trial, he testified that he was asleep in his sister’s home during the entire morning the robbery took place. His story was corroborated by the testimony of his sister and her two daughters, all of whom testified that the defendant did not leave the house that day.4 The undisclosed version of the robbery that Pfister gave in the police report certainly lends credence to Garrison’s con*1277tention that he was absent from the scene of the crime. Consequently, I believe that the police report would have been useful not only for impeachment purposes, but would have enhanced Garrison’s substantive alibi defense as well.
The notion that a witness’s prior inconsistent statements may constitute substantive exculpatory evidence, in addition to being useful for impeachment, is not a new one. In Giles v. Maryland, 1967, 386 U.S. 66, 87 S.Ct. 793, 17 L.Ed.2d 737, a supr pressed police report contained statements that were inconsistent with the prosecutrix’s testimony at trial concerning whether a certain defendant had raped her. Justice Brennan, speaking for a plurality of the Court, found that this evidence went “not only to the credibility of the State’s witnesses, but also to the issue at trial whether [the defendant] had raped the girl”. 386 U.S. at 77, 87 S.Ct. at 798-99, 17 L.Ed.2d at 746. See also Alcorta v. Texas, 355 U.S. 28, 31-32, 78 S.Ct. 103, 105, 2 L.Ed.2d 9, Í2. This circuit reached a similar conclusion in Davis v. Heyd, 5 Cir. 1973, 479 F.2d 446. Davis involved the nondisclosure of a státement given by one of the witnesses to a shooting, shortly after the event, that contradicted his trial testimony with respect to when the defendant drew his giin. We found that the prosecution’s failure to disclose the prior statement required á reversal of the conviction because the statémént “specifically corroborated [the defendant’s] defense of accidental discharge and specifically contradicted the [prosecution witness’s] trial version of intentional killing in the heat of a struggle”. 479 F.2d at 453.
Even if the prosecution’s duty to disclose impeaching evidence should be governed by a more stringent materiality standard than its obligation to reveal exculpatory matter, I cannot agree that the stricter standard should be applied in a case, such as this one, where the undisclosed evidence is both exculpatory and impeaching. Characterization problems similar to the one in this casé will undoubtedly arise whenever the evidence undisclosed by the prosecution involves a statement by an important prosecution witness that conflicts with his testimony at trial. Thus, the distinction the majority draws between exculpatory and impeaching evidence, for purposes of prosecutorial disclosure, is not only unnecessary; it is largely unworkable.
III.
In determining whether “the omitted evidence creates a reasonable doubt that did not otherwise exist” — the standard of materiality that I believe should be applied in this case — the Court in Agurs insisted that “the omission must be evaluated in the context of the entire record”. -U.S.-, ——, 96 S.Ct. at 2402, 49 L.Ed.2d at 355. This is precisely what the district judge did in reaching the conclusion that a reversal of Garrison’s conviction was necessary.
Even under a stringent standard of materiality, the victim’s inconsistent description of the robbers contained in the police report is so pertinent to his credibility at trial that its nondisclosure requires a reversal of the petitioner’s conviction. The only positive identification of Garrison was made by Pfister, the victim of the armed robbery. Pfister’s description of his assailant made the day following the crime and contained in the police report is of a man some 8" taller than Garrison. Without the benefit of this prior inconsistent description, the defense was unable to successfully impeach Pfister’s testimony, which was crucial to the State’s case. .
. . It is enough to say that the two descriptions, inconsistent on their face, would provide the defense counsel with ample grounds to attempt to impeach Pfister’s testimony. Such impeachment, if successful, would have been fatal to the State’s case. (Emphasis added.)
These findings are more than amply supported by the record and should not be disturbed.5
*1278I wish to stress that the Court’s decision still leaves Garrison free to assert that the undisclosed police report was sufficiently material to entitle him to a reduction in punishment. Brady v. Maryland, 1963, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215. The 99-year sentence imposed on Garrison, the maximum under Louisiana law,6 apparently was a product of Pfister’s unequivocal trial identification of Garrison as the robber who bludgeoned him with a shovel. A doubt cast on the truth or correctness of Pfister’s testimony might have resulted in a far shorter prison term for Garrison.
The Court today formulates a severe materiality standard to govern the prosecution’s duty to reveal impeaching evidence, and denies the petitioner here relief, because it fears that “forcing disclosure of impeachment matter may actually inhibit a full presentation to the trier of fact”. 540 F.2d at 1274. Even if this were true, the concern is misplaced in a case, such as this one, where the impeaching evidence comes into the prosecution’s hands in the normal course of its investigation, and goes solely to the witness’s recollection and perception of events rather than to his honesty and veracity. To the extent that the Court’s fear is well founded, the materiality standard announced by the Supreme Court in Agurs is strict enough to combat the problem. No need exists to impose on prosecutors, the district courts, and ourselves the burden of drawing the often ethereal distinction between exculpatory and impeaching evidence. Under the Agurs materiality standard, Garrison is clearly entitled to the relief granted by the district court. I would therefore affirm.
. Giglio held that where the prosecution knows or should know that testimony going to the credibility of a key prosecution witness is inaccurate, and the prosecution fails to correct such testimony at trial, a conviction must be set aside if there is any reasonable likelihood that the false testimony could have affected the judgment of the jury. 405 U.S. at 154, 92 S.Ct. at 766, 31 L.Ed.2d at 108. See United States v. Agurs,- U.S. -, 96 S.Ct. 2392, 2397, 49 L.Ed.2d 342, 349-50. The majority finds the strict holding of Giglio, — including the lower materiality threshold that case requires for reversal — inapplicable here. After reading the record, I must agree. The following colloquy took place during the defense cross-examination of James H. Pfister, the victim of the robbery and the prosecution’s key witness.
Q. Now, do you recall the description of the individual who put the gun on you, the one that held it in front of you, that stood in front of you? What was his physical description in general? Did you talk to the Police?
A. I talked to the Police, yes.
Q. What description did you give?
A. On the way to the hospital they were asking me as I was riding. They were asking me then, you know.
Q. What description did you give the Police?
A. I told the Police that he was—
Q. Which is he, which one?
A. Right here. I told them about the other fellow being about 5' 10" or 5' 11", and that the other fellow was shorter, that I imagined that he was about 5' 4" or 5' 5",
*1276Record on Appeal, Vol. I, pp. 201-202. Because of the unclarity of Mr. Pfister’s testimony, it is impossible to say that he was contradicting his earlier statements to the police. Consequently, it cannot fairly be said that the prosecution knew, or should have known, about any inaccuracies in Mr. Pfister’s trial testimony.
. For purposes of the prosecution’s duty to disclose evidence favorable to the defense, the prosecutor need not have possessed the evidence if it was in the custody of government agents, including the police. Smith v. Florida, 5 Cir. 1969, 410 F.2d 1349, 1351; Barbee v. Warden, Maryland Penitentiary, 4 Cir. 1964, 331 F.2d 842, 846. See Comment, Brady v. Maryland and the Prosecutor’s Duty to Disclose, 40 U.Chi.L.Rev. 112, 124-125 (1972).
. Garrison’s alleged partner in the crime has never been apprehended.
. At the evidentiary hearing conducted in response to Garrison’s state petition for habeas corpus, the prosecutor who tried Garrison’s case testified that he thought Garrison’s alibi witnesses were credible. Record on Appeal, Vol. I, pp. 149-150.
. The prosecutor who tried Garrison gave the following testimony at the state habeas evidentiary hearing.
Q. Does that inconsistency [in Pfister’s descriptions of his assailant] support your case?
*1278A. Would it have supported it; no. It would have been contradictory, the inconsistency about what the victim allegedly stated to officer Schneider. It was — Ran [sic] completely counter to what was testified to at the trial, and what Mr. Pfister indicated the facts were when I saw him. .
Q. Mr. Marcal, as a prosecutor do you consider the inconsistency there to be material?
A. Well, if it would have been directly brought to my attention, I think it would have been material; it would have been very material had it been brought to my attention.
Q. And as I recall, it’s your testimony that you have no independent recollection of that inconsistency coming to you?
A. No it doesn’t, other than the feeling that — a general feeling about this case. It started with Officer Favolora in the hallway, that he had better do some work on it, that the recollection of one person perhaps wasn’t sufficient.
