David Gene Lewis, a former California correctional officer, appeals the district court’s denial of his motion to dismiss the indictment. Lewis raises two issues. First, can Lewis seek interlocutory review of the district court’s denial of his “fair warning” defense? Second, did the prosecution’s alleged Brady 1 violations raise double jeopardy concerns? We answer both questions in the negative.
*1104 Background
This matter springs from an incident on June 20, 1994, when Lewis, then a correctional officer at Pelican Bay State Prison, shot and seriously wounded an inmate, Harry Long, during a prison-yard disturbance. Five years after the shooting, a federal grand jury charged Lewis with violating 18 U.S.C. § 242, Deprivation of Rights Under Color of Law, and 18 U.S.C. § 924(c), Use of a Firearm in Relation to a Crime of Violence. One year after the indictment, the Government tried Lewis, and a jury convicted him of both counts.
In January 2002, in an unpublished disposition, we reversed Lewis’s convictions and remanded for a new trial. In reversing, we held that the district court had committed error by excluding from trial a Shooting Review Board Report. At a status hearing after remand, the Government revealed that it had just learned about potentially exculpatory material that it had not previously shown to Lewis. The two allegedly withheld pieces of information were (1) statements by Long that his fellow combatant in thе prison yard had a weapon and (2) a statement by a fellow prison guard that “it would be very difficult to see what was really happening” from .the tower where Lewis shot Long.
Lewis moved to dismiss the prosecution against him on fair warning and double jeopardy grounds. The district court denied the motion, and Lewis appealed. The district court subsequently vacated the trial date pending appeal.
Discussion
A. Lewis’s Fair Warning Claim
The fair warning requirement ensures that “no man shall be held criminally responsible for conduct which he could not reasonably understand to be proscribed.”
United States v. Harriss,
Under 28 U.S.C. § 1291, criminal cases generally are not subject to appellate review “until after conviction and sentence.”
See Flanagan v. United States,
Nevertheless, the Supreme Court has warned against broadening the scope of interlocutory review in criminal cases. Piecemeal appeals encourage delay, which “is fatal to the vindication of the criminal law.”
United States v. MacDonald,
A major characteristic of an appealable claim under the collateral order doctrine is that “unless it can be reviewed before [the рroceedings terminate], it can never be reviewed at all.”
Mitchell v. Forsyth,
Lewis argues that the fair warning requirement similarly shields him from criminal prosecution, rather than merely providing a defense to conviction. In doing so, Lewis points to the Supreme Court’s statement that fair warning and qualified immunity serve similar objectives: “to give officials (and, ultimately, govеrnments) the same protection from civil liability and its consequences that individuals have traditionally possessed in the face of vague criminal statutes.”
United States v. Lanier,
While noting the two doctrines’ similar purpose, the Court in
Lanier
did not hold that the fair warning requirement insulates a criminal defendant from standing trial, as qualified immunity does for a civil defendant. Rather, the Court held that qualified immunity provides officials “the same protection from civil
liability
that individuals have traditionally possessed in the face of vague criminal statutes.”

Not only do we lack authority to expand the fair warning requirement’s scope, the rules of criminal procedure give us good reason not to do so. A district court can only grant a dismissal in the criminal context if the issue is “ ‘entirely segregable’ from the evidence to be presented at trial.”
United States v. Shortt Accountancy Corp.,
Here, Lewis’s fair warning claim involves questions inextricably intertwined with the question of his alleged guilt. The gоvernment accuses Lewis of willfully depriving Long of his Eighth Amendment right against cruel and unusual punishment. Specifically, the government charged Lewis, in part, with violating 18 U.S.C. § 242. That code section makes it a criminal act to act “(1) ‘willfully’ and (2) under color of [state] law (3) to deprive a person of rights protected by the Constitution or laws of the United States.”
Lanier,
We recognize that, in certain situations, courts may dispose of factual questions underlying immunity defenses before subjecting the defendant to a criminal trial. For instance, courts may decide the facts supporting a double jeopardy claim or the scope of an immunity agreement before allowing the jury to deliberate on guilt.
See, e.g., United States v. Anderson,
The fair warning doctrine may ultimately protect Lewis from criminal liability. That, however, is an issue we can review after judgment, if necessary. We therefore dismiss the interlocutory appeal of Lewis’s fair warning claim.
B. Lewis’s Double Jeopardy Claim
Lewis contends that the prosecution’s alleged Brady violations at his initial trial implicаte the Double Jeopardy Clause. Specifically, Lewis claims that during the original trial the prosecution withheld certain exculpatory statements by Long and a fellow prison guard. He alleges that the Government committed these violations to avoid acquittal.
*1107
Courts typically review
Brady
violations post-trial.
See United States v. Smith,
We have never addressed whether a defendant can invoke the Double Jeopardy Clause due to a prosecutor’s alleged Brady violation. Other circuits, however, have expliсitly held that defendants may not invoke the Double Jeopardy Clause in such circumstances. We agree with the conclusions of those circuits.
As the Third Circuit noted,
Brady
serves the limited purpose of ensuring a defendant’s due process right to a fair trial.
United States v. Coleman,
Barring a retrial for the prosecution’s alleged intentional
Brady
violations would be an unnecessary expansion of the Double Jeopardy Clause. Courts have authority to police a prosecutor’s ethical misconduct.
See United States v. McClintock,
The record here does not suggest prоse-cutorial misconduct, and Lewis does not merit relief on these grounds. As the district court noted, Long’s testimony about the alleged weapon was “all over the board.” Long consistently testified before trial that no such weapon existed. Only after trial did Long testify about a possible weapon. Long’s testimony regarding the prоsecutor’s instructions was similarly inconsistent. While he blamed the prosecutor for dissuading him from mentioning the razor blade earlier, Long also stated that no agent or prosecutor ever told him to lie. Concerning the other correctional officer’s testimony, the Government had *1108 fully disclosed her name and position to the defense before trial. The guard did not witness the fight or shooting.
We note an additional problem for Lewis’s double jeopardy claim. Double jeopardy ordinarily does not apply if a defendant obtains a mistrial. Courts presume that the defendant, in seeking a mistrial, gives up his or her right to a verdict by that jury.
See United States v. Tateo,
Here, Lewis does not allege that the prosecution provoked him into moving for a mistrial. The case, in fact, went to the jury; Lewis did not learn of the alleged misconduct until after he overturned his conviction on appeal. We have not directly addressed whether the Double Jeopardy Clause applies in such a case.
Other circuits, however, have declined to broaden the scope of the Double Jeopardy Clause in this fashion. The Tenth Circuit, for instance, noted that “without the declaration of a mistrial, [defendants are] not deprived of their ‘valued right’ to have their case submitted to the first jury.”
United States v. McAleer,
We are aware that the Second Circuit has surmised, in dicta, that the Supreme Court “might think” that the Double Jeopardy Clause protects a defendant from retrial in instances other than after successful motions for mistrial.

See United States v. Wallach,
Several subsequent cases have referenced the reasoning in
Wallach.
None, however, concluded that the relevant pros-ecutorial misconduct was sufficiently egregious to bar a retrial.
See, e.g., United States v. Gary,
Lewis has received one of the remedies that Brady envisions, a new trial. The prosecution’s alleged Brady violations in this case simply do not implicate the Double Jeopardy Clause or otherwise bar his retrial. The district court thus did not err in rejecting Lеwis’s double jeopardy claim.
CONCLUSION
We DISMISS Lewis’s fair warning claim for lack of jurisdiction. Although we have jurisdiction over his double jeopardy claim because it raises a colorable claim, the substance of that double jeopardy claim lacks merit. We therefore AFFIRM the district court’s denial of Lewis’s motion to dismiss with respeсt to the double jeopardy claim.
DISMISSED, in part, and AFFIRMED, in part.

Maryland,

Lanier
involved a defendant, state judge David Lanier, who was convicted under 18 U.S.C. § 242 for criminally violating the constitutional rights оf five women by sexually assaulting them while he was in state office. The Supreme Court overturned the Sixth Circuit's conclusion that criminal liability could be imposed under § 242 only if the Supreme Court had previously identified the constitutional right at issue in a case with fundamentally similar facts.
Lanier,
. Notably, qualified immunity and fair warning derive from two entirely separate sources. The fair warning requirement, which springs from the Due Process Clause, protects a defendant from сriminal liability.

Kastigarv. United States,
. To justify dismissing an action for prosecu-torial misconduct, "the government’s conduct must have caused substantial prejudice to the defendant and been flagrant in its disregard for the limits of appropriate professional conduct.”
United States v. Lopez,
. After speculating that prosecutorial misconduct designed to avoid acquittal might justify such an expansion, the court concluded that the case then before it did not involve the type of deliberate misconduct that might invoke a double jeopardy bar to retrial.
