dissenting, joined by McMILLIAN, Circuit Judge.
I vote to grant the suggestion for rehearing en banc. I also vote to grant the motion for stay of execution until final disposition of the instant appeals in this Court.
This is a Brady case. The petitioner, Robert Earl O’Neal II, asked the prosecution, before his trial in the state court, whether any of the State’s witnesses had a criminal record. The State said no. This was not a correct answer. In fact, one of the State’s two key eyewitnesses, Correctional Officer John Maylee, had been convicted of three felonies. In other words, the State of Missouri broke the law in this case. In fact, it broke the highest law — the Constitution of the United States.
The District Court dismissed this claim, asserted by O’Neal’s second habeas petition, as abusive. The claim was not alleged in O’Neal’s first habeas petition. So the question is whether O’Neal can show cause for and prejudice resulting from this omission. The District Court held, on the issue of cause, that “O’Neal has failed to explain why he could not have obtained the factual basis of his claim prior to filing the first petition by either questioning a witness or reviewing public records.” Robert Earl O’Neal, II v. Michael Bowersox, No. 4:95CV02140 GFG, *171slip op. 5 (E.D.Mo., November 29, 1995). A panel of this Court has agreed that “O’Neal has failed to show why he could not have obtained the factual basis of the claim prior to filing his first petition.” Robert Earl O’Neal, II v. Michael Bowersox, 73 F.3d 169, 170 (8th Cir.1995) (per curiam).
I believe these statements are both true. O’Neal’s lawyers could have obtained the information long ago either by interviewing Officer Maylee, which is what counsel for Lloyd Schlup, a co-defendant, did, or by searching the public record. (The prosecution also took neither of those steps.) But the law places no such duty on defense counsel. A defense lawyer who asks for this sort of potentially helpful evidence should be entitled to rely on the accuracy of the State’s response. He should not be required to behave as if the prosecuting attorney cannot be trusted. Failure to reveal exculpatory evidence in violation of Brady is itself “cause” for present purposes. It is an “ ‘objective factor external to the defense [that] impeded counsel’s efforts’ to raise the claim_” McCleskey v. Zant, 499 U.S. 467, 493, 111 S.Ct. 1454, 1470, 113 L.Ed.2d 517 (1991), quoting Murray v. Carrier, 477 U.S. 478, 488, 106 S.Ct. 2639, 2645-46, 91 L.Ed.2d 397 (1986). We so held in Fairchild v. Lockhart, 979 F.2d 636, 640 (8th Cir.1992) (Magill, J.), cert. denied, — U.S. -, 113 S.Ct. 3051, 125 L.Ed.2d 735 (1993) (subsequent history omitted). Accord, 979 F.2d at 641, 642 (Arnold, C.J., concurring). In holding otherwise, the panel has departed from a prior panel opinion, which is grounds for rehearing en banc. 8TH CIR.R. 35A(a).
But what about “prejudice”? Is there “a reasonable likelihood that, if the withheld evidence had been introduced at trial, the verdict would have been different”? 979 F.2d at 642 (concurring opinion). Or, as the Supreme Court has most recently put it, could the undisclosed evidence “reasonably be taken to put the whole case in such a different light as to undermine confidence in the verdict”? Kyles v. Whitley, — U.S. -, -, 115 S.Ct. 1555, 1566, 131 L.Ed.2d 490 (1995). I frankly do not know. I do not know how anyone could know without reading the transcript of O’Neal’s trial. The withheld material relates to a witness’s credibility, I concede, and not directly to O’Neal’s guilt or innocence, but credibility of eyewitnesses (officers vs. inmates) seems to be what this trial was about. O’Neal killed Arthur Dade, but he said he acted in self-defense, and the eyewitnesses told different stories on that issue. The State thought criminal records were important enough to use to impeach O’Neal’s witnesses. At the very least, the suggestion for rehearing en banc presents a persuasive theory of Brady prejudice. See Suggestion, pp. 8-13.
I have not read the trial transcript. The Suggestion for Rehearing En Banc arrived in my chambers by FAX at about 11 o’clock this morning, Monday, December 4, 1995. A call to our Clerk’s Office, made before noon, revealed that the transcript was lodged with the Clerk of the District Court. At my request, the transcript has been sent to and is now (this is being written at 3:30 p.m.) in the Clerk’s Office of this Court. The transcript is hundreds of pages long. It cannot get from St. Louis to Little Rock (where I now am) before tomorrow. The execution is set for a little more than 32 hours from now. I do not believe it would be responsible for me to order the transcript to be sent to me now. The Supreme Court might want to see it. But in the meantime, I decline to vote to send Mr. O’Neal to his death before someone, either on this Court or the Supreme Court, has read the transcript with O’Neal’s Brady claim in mind.
I would stay this execution pending rehearing by this Court en banc.
