The United States appeals from the dismissal, on due process grounds, of an indictment against defendant-appellee Ronald A.X. Stokes. Because the district court acted improvidently and in excess of its authority, we reverse.
I. BACKGROUND
The factual foundation of the case is laid elsewhere,
see United States v. Stokes,
Boston police officers arrested Stokes on December 6, 1990, and charged him with first-degree murder, unlawful carriage of a firearm (an AK-47 semi-automatic rifle), and two counts of assault and battery with a dangerous weapon. On August 11, 1992, a state court jury acquitted him on the murder charge, but convicted him on the other three *42 counts. Mindful of both the circumstances of the crimes and the defendant’s recidivism, the judge sentenced him at or near the statutory maximum for each count and made the sentences consecutive. Stokes’ anticipated release date from state confinement is in 2006.
The federal government knew of Stokes’ ease no later than June 9, 1993. Still, the federal behemoth did not stir until December 5, 1995, when the United States charged Stokes with being a felon in possession of a firearm. See 18 U.S.C. § 922(g)(1) (1994). Stokes moved to dismiss the federal indictment on temporally oriented grounds. He averred that the prosecution was time-barred and that the protracted preindictment delay violated (a) his Fifth Amendment right to due process, (b) his Sixth Amendment right to a speedy trial, and (c) the strictures of Fed.R.Crim.P. 48(b). Following a hearing, the district court took the unorthodox step of submitting a series of interrogatories to the government sua sponte.
In the course of those proceedings, the government explained, among other things, that this prosecution would further the federal interest in protecting the public from a violent criminal. The government noted that Stokes, who had accumulated an unrelieved record of bellicose criminality, on this occasion had wielded a particularly lethal weapon, and that, if -he were to be convicted on the federal charge, he could be punished as an armed career criminal.

The court eventually rejected each of Stokes’ claims. Because the five-year statute of limitations commenced running on December 7, 1990, the indictment, handed up on December 5, 1995, was timely.
See United States v. Stokes,
Had the district court stopped at this juncture, these proceedings would be unnecessary. But the judge brooded over the sentencing possibilities. Noting that, regardless of the earlier acquittal, Stokes’ sentence could be enhanced to life imprisonment without parole if the government obtained a conviction on the federal weapons charge and then proved at sentencing by a preponderance of the evidence that he had committed the murder,
see generally
USSG § 2K2.1; USSG § 1B1.3(a), the judge foresaw “vexing issues” of due process, double jeopardy, and selective prosecution.
United States v. Stokes,
II. DISCUSSION
Because the district court’s dismissal of the indictment on constitutional grounds raises a pure question of law, we exercise plenary review.
See United States v. Nippon Paper Indus. Co.,
A. Aggregate Effect.
The cornerstone of the district court’s order is its conclusion that a medley of constitutional concerns, each insufficient to bar prosecution, added up to a due process violation and required dismissal of the indictment. The district court cited
United States v. Lombard,
A state court jury acquitted Lombard on murder charges. A federal court jury subsequently convicted him on federal firearms charges arising out the same nucleus of operative facts. The trial judge imposed a mandatory life sentence based on preponderant evidence that Lombard used the weapons to commit the murders (of which he previously had been acquitted).
See id.
at 172. Expressing but not resolving constitutional concerns about, inter alia, the magnitude of the sentence enhancement, the prior acquittal, the qualitative difference between the sentence-enhancing conduct and the offense of conviction, and the severity of the sentence imposed, the court held that this combination of special facts permitted the district court to consider a downward departure at sentencing.
See id.
at 180, 184-85;
see also United States v. Lombard,
Lombard I
offers no support for the dismissal of the indictment in this case.
Lombard
7 is a sentencing case, elaborating on departure principles, and its analysis is unique to the milieu of the federal sentencing guidelines.
See Lombard I,
Moreover, Judge Harrington’s reading of
Lombard I
is undone by
Lombard II
(which, in all fairness, was decided some two weeks after Judge Harrington ruled).
Lombard I
resulted in a remand for further consideration of the appropriate sentence.
In a gallant effort to hold his gains, Stokes’ able counsel points out that we have recognized in other contexts the principle of cumulative effect.
See, e.g., United States v. Sepulveda,
*44 B. Sentencing Considerations.
The court below dwelt at some length on the potentially severe sentence that Stokes might receive if he were convicted on the federal charge. The court’s reliance on this factor as a basis for granting relief was at best premature.
In the normal course of events, a facially valid indictment returned by a duly constituted grand jury calls for a trial on the merits.
See Costello v. United States,
This principle applies in regard to sentencing: when the supposed constitutional infirmity derives from particular attributes of a sentence imposed, the scope of relief is limited to excising the taint from the sentence.
See, e.g., Coker v. Georgia,
The anatomy of the doctrine of prein-dietment delay strengthens our conviction that Judge Harrington prematurely considered post-conviction possibilities. Dismissal for preindietment delay on due process grounds requires, inter alia, a showing of actual prejudice.
See United States v. Marion,
To recapitulate, sentencing issues are properly addressed during the sentencing phase of federal criminal trials. The district court’s flagrant contradiction of this tenet constituted legal error.
C. Miscellaneous Grounds.
Stokes attempts to confess and avoid. If the district court erred in its reasoning, he *45 says, its result nevertheless is defensible as a condign remedy for prosecutorial vindictiveness, or as a eoncinnous exercise of the court’s supervisory powers, or because the district court erred when it failed to dismiss the indictment on the basis of preindictment delay. We weigh each asseveration.
1.
Prosecutorial Vindictiveness.
It is hornbook law that a federal court may dismiss an indictment if the accused produces evidence of actual prosecutorial vindictiveness sufficient to establish a due process violation, or even if he demonstrates a likelihood of vindictiveness sufficient to justify a presumption.
See United States v. Goodwin,
We begin this segment of our analysis with a caveat: courts should go very slowly in embracing presumptions of prose-cutorial vindictiveness in pretrial proceedings.
See Goodwin,
The level of difficulty increases due to the breadth of the prosecutor’s discretion. A federal prosecutor does not have the resources (time, money, staff) to charge every suspected malefactor. In picking and choosing, the prosecutor must act in a fair and even-handed manner, and he is constrained by a set of rules and conventions (both legal and ethical). But prosecutors are not required to function as bloodless automatons: they may (indeed, they should) make judgments about dangerousness, set priorities, and give heightened attention to cases which inspire a sense of outrage. This ease illustrates the point: the government’s decision to refrain from initiating federal criminal proceedings pending the outcome of a parallel (but independent) state prosecution, and to relax the self-imposed restraint only after it had been disappointed by the end result of the parallel proceeding, falls squarely within the eneincture of this prosecutorial discretion.
See United States v. Fuzer,
We need not wax longiloquent. Simply put, the district court’s inscrutable reference to vindictiveness fails to compensate for the utter absence of any circumstances from
*46
which a trier legitimately could presume vindictiveness.
See United States v. Sutherland,
2.
Supervisory Powers.
The dismissal is equally vulnerable if viewed as an exercise of the district court’s supervisory powers. Such powers enable courts, within limits, to formulate procedural rules not specifically contemplated by the Constitution or codified in positive law.
See United States v. Hasting,
The district court did not explicitly invoke its supervisory powers, but it did voice lingering concerns about “fundamental fairness” and “fair play.”
United States v. Stokes,
Although dismissing an indictment on substantive due process grounds is not unprecedented, it is extremely rare. Such a drastic step is reserved for cases of “serious and blatant prosecutorial misconduct that distorts the integrity of the judicial process.”
United States v. Giorgi,
In this vein, Stokes’ flagship case,
United States v. Rodman,
We give short shrift to Stokes’ related allegation that the indictment was subject to dismissal because of prosecutorial abuse of sentence enhancers. A pretrial dismissal on this basis constitutes a totally inappropriate use of the court’s supervisory powers.
See supra
Part 11(B);
see also Horn,
Finally, to the extent that Judge Harrington was influenced in his ruling by his evident personal disagreement with the government’s decision to prosecute Stokes under federal law, his action was inappropriate. It is a bedrock principle of our system of criminal justice that “the Due Process Clause does not permit courts to abort criminal prosecutions simply because they disagree with a prosecutor’s judgment as to when to seek an indictment.”
United States v. Lovasco,
In sum, the record contains no inkling of prosecutorial misconduct, vindictiveness, or other conduct antithetic to substantive due process which could justify dismissing the indictment through the exercise of the court’s supervisory powers.
3.
Preindictment Delay.
Stokes’ renewed claim of unconstitutional preindict
*47
ment delay lacks substance. A criminal defendant who asserts such a claim bears the heavy burden of showing not only that the preindictment delay caused him actual, substantial prejudice, but also that the prosecution orchestrated the delay to gain a tactical advantage over him.
See Marion,
Stokes argues that he satisfied the first prong of the test because, had the federal government promptly indicted him, he would have continued searching for a potential defense witness, Sherry Parkman, who disappeared between the date of the offense and the date of the state court trial. Since the appellee was unable to locate the witness at the time of his state trial, there is no credible reason to believe that the delay on the federal side placed him in a position less advantageous than he would have occupied had the indictments been contemporaneous. 5
The appellee’s fallback position is that the delay prejudiced him by denying him the benefit of running his state and federal sentences concurrently. This is pure speculation and, hence, inadequate to the task.
See McCoy,
At the expense of carting coal to Newcastle, we add that Stokes also fails on the second prong of the test. By all accounts, the government temporized until it knew the result of the state court prosecution. Even then, the government deferred an indictment because it gave priority to the prosecution of offenders who, unlike Stokes, were not already in custody.
The government’s explanation is plausible and unimpeached; it should, therefore, be accepted.
See United States v. Marler,
III. CONCLUSION
We need go no further. It is evident to us that the district court erred as a matter of law in dismissing the case prior to trial. Having obtained a valid indictment within the limitations period, the government is entitled to try the defendant on the merits. Moreover, we think it best that the case be transferred to a new trier on remand, and we so direct.
See, e.g, United States v. Muniz,
Reversed.

. The United States Attorney obtained an authorized waiver from the Justice Department’s Petite policy, an aspirational protocol which seeks to prevent overlapping federal-state prosecutions absent a compelling federal interest.

. The judge wrote, somewhat cryptically: "It is not fitting for the United States to be vindic-tive____"
United States v. Stokes,
. Among other things, showing vindictive prosecution where two separate sovereigns are involved would require a finding of complicity between federal and state prosecutors.
