Antowine Mitchell (“Mitchell”) appeals his conviction for bank robbery. He maintains that: (1) the district judge should have conducted an in camera inspection of the presentence reports of three accomplice witnesses to determine whether the reports cоntain Brady material, (2) there was insufficient evidence to support the jury’s verdict, (3) the testimony of four of the government’s witnesses was obtained in violation of the federal anti-bribery statute, 18 U.S.C. § 201(c)(2), and (4) the district court should have reduced Mitchell’s offense level by two because he was a minоr participant in the offense, U.S.S.G. § 3B1.2(b). We reject these arguments and affirm the district court’s judgment in all respects.
I. BACKGROUND
On August 8, 1997, the North Shore Bank in Racine, Wisconsin was robbed. One of the robbers, Walter Williams (“Williams”), handed a teller a note that said “give me the money or I’ll shoot you don’t do anything stupid.” The teller gave him approximately five thousand dollars, and he left the bank. Mitchell followed him out. On February 10, 1998, Mitchell was charged with one count of bank robbery, in violation of 18 U.S.C. §§ 2113(a), 2.
The witness list at Mitchell’s trial shows that there is indeed no honor among thieves. Williams, who pled guilty to the North Shore Bank rоbbery, testified that on August 8, 1997, he, Bridget Womack (“Womack”), and Mitchell drove to the North Shore Bank and parked across the street. Womack then wrote out two demand notes and gave one each to Williams and Mitchell. The plan was for Williams and Mitchell to approach twо tellers simultaneously and present the demand notes. Williams and Mitchell left the car and went into the bank carrying the demand notes. Because the bank was very busy, however, Mitchell was left standing at a service counter while Williams approached a teller. After the teller gavе Williams the money, he and Mitchell left the bank and ran to the car where Womack was waiting. The money was divided up a short time later.
Womack testified that she, Williams, and Mitchell had robbed the North Shore Bank on August 8, 1997. She also testified that she wrote out two demand notes, that Williams and Mitchell entered the bank with the notes intending to approach two tellers at once, and that Williams and Mitchell told her that only Williams had approached a teller because the bank had been so busy.
Natasha Williams testified that her husband, Williams, as well as Womack and Mitchell drove off together in two cars on the morning of August 8, 1997. She also testified that Williams arrived home at *907 2:00 a.m. the next morning accompanied by Mitchell.
Finally, Joshua Taylor (“Taylor”) testified that Mitchell had discussed the bank robbery with him while the two were in jail together. Mitchell told Taylor that he went into a bank with his friend in order to help his friend rob the bank, but did not end up aрproaching a teller. Mitchell also told Taylor that he acted as a lookout during the robbery.
When Mitchell found out that his accomplices would be testifying against him, he requested that the district judge review their presentenee reports in camera for impeachment mаterial. The district judge denied the motion. (Order of April 15, 1998.) Nonetheless, Mitchell did not lack impeachment material. For example, at the time of Mitchell’s trial, Williams, Natasha Williams, Womack, and Taylor were each bound by plea agreements that required that they provide substantial assistance to the government. All four witnesses testified that they had not been promised anything by the government in return for their testimony, but that they hoped that their cooperation would be considered at their own sentencing hearings. All the relevant plea agreements were introduced into evidence at trial.
After a five day trial, the jury found Mitchell guilty of the single count of bank robbery. On August 17, 1998, the judge sentenced Mitchell to eighty-five months of imprisonment. This appeal followed.
II. DISCUSSION
A. In Camera Inspection of Presen-tence Reports
Mitchell challenges the district court’s refusal to conduct an in camera inspection of the presentence reports of Williams, Natasha Williams, and Womack. Mitchell argues that such an inspection was required by
Brady v. Maryland,
In
Brady,
the Supreme Court held that “the suppression by the prosecution of evidence favorable to an accused upon request violates due process where the evidence is material either to guilt or to punishment.”
Mitchell’s argument is misguided. As we have explained before, a “due process standard which is satisfied by mere speculation would convert
Brady
into a discovery device and imрose an undue burden upon the district court.”
United States v. Morris,
We have been guided by this principle in several cases. In
Morris,
we held that the district judge was not required to conduct an in camera review of FBI reports on a government witness because the defendant could not offer anything beyond speculation to indicate that the reports containеd
Brady
information and because the government claimed that it had turned over all
Brady
material.
Mitchell’s case closely parallels Morris, Andrus, and Navarro. There is no indication that the presentence reports of Williams, Natasha Williams, and Womack contain undisclosed Brady material. Furthermore, the district judge found that the government was “well aware of its obligations under Brady.” (Order of April 15, 1998.) In addition, as the magistrate judge noted, the government’s open file policy provides defendants with “more discovery materials than the defendant would be entitled to obtain under strict adherence to the federal rules.” 1 (Order of March 25, 1998.) Under these circumstances, the district judge concluded that there was no need to examine the presen-tence reports in camera. (Order of April 15,1998.) We are inclined to agree.

United States v. Anderson,
B.Government Agreements with Witnesses
Mitchell contends that the government’s agreements with Williams, Natasha Williams, Womack, and Taylor violate the federal antibribery statute, 18 U.S.C. § 201(c), and that any testimony resulting from the agreements should have been suppressed. The anti-bribery statute makes it illegal to “dirеctly or indirectly, give[ ], offer[ ] or promise[ ] anything of value to any person, for or because of the testimony under oath or affirmation given or to be given by such person as a witness upon a trial, hearing, or other proceeding, before any court.” 18 U.S.C. § 201(c)(2). Mitchell argues that whеn the government promises to file a motion for a downward departure if a witness provides substantial assistance, the government has promised something “of value” in exchange for testimony. This argument has become popular since the Tenth Circuit briefly adopted it in
United States v. Singleton,
C. Sufficiency of the Evidence
In a reprise of his argument that the plea agreements of Williams, Natasha Williams, Womack, and Taylor violate the federal anti-bribеry statute, Mitchell argues that there was insufficient evidence to support his conviction because the only evidence offered at trial was inconsistent testimony given in the hope of receiving a lower sentence. As we have often explained, “when we review for suffiсiency of evidence, the appellant ‘faces a nearly insurmountable hurdle ... [in that] we consider the. evidence in the light most favorable to the Government, defer to the credibility determination of the jury, and overturn a verdict only when the record contains no evidencе, regardless of how it is weighed, from which the jury could find guilt beyond a reasonable doubt.’ ”
United States v. Szarwark,
Under this standard, Mitchell’s claim clearly fails. By Mitchell’s own admission, the plea agreements of the witnesses were entered into evidence and each witness testified that he or she hoped to obtаin a reduced sentence by testifying. The jury was presented with impeaching evidence and chose to credit the witnesses’ testimony anyway. That was their right.
United States v. Alcantar,
D. Minor Participant Reduction
Mitchell’s final contention on appeal is that the district court should have
*910
decreased his offense level by two because he was a minor participant in the offense. U.S.S.G. § 3B1.2(b). A minor participant is “any participant who is less culpable than most other participants.” U.S.S.G. § 3B1.2(b), Application Note 3. It is the defendant’s burden to show by a preponderance of the evidence that he is entitled to a minor participant sentence reduction.
United, States v. Brisk,
Mitchell argues that he falls within the definition of a minor participant because he did not plan the robbery and did nothing to help execute it. Hе emphasizes that he did not even approach a teller. We are not persuaded. Mitchell had full knowledge of the plan to rob the North Shore Bank. He accompanied Williams into the bank for the purpose of committing the robbery. He took a note with him that threаtened violence and demanded money. It just so happened that Mitchell found the bank too crowded to allow him to present his note to a teller at the same time as his accomplice. The Sentencing Guidelines provide for a lesser punishment when the defendant is lеss
culpable
than other participants in the offense. Fortuity has no bearing on culpability. Therefore, Mitchell has not shown that he is less culpable than Williams and is not entitled to a minor participant sentence reduction.
See United States v. Covarrubias,
Conclusion
For the foregoing reasons, the district court’s judgment is Affirmed in all respects.
Notes
. The government informs us that "[i]ncluded within the material disclosed pursuant to [the open file policy of the U.S. Attorney's Office for the Eastern District of Wisconsin] is all material discoverable under Rule 16 of the Federal Rules of Criminal Procedure and exculpatory material pursuant to Brady and its progeny.” (Appellee’s Brief at 13.)
