                             OPINION

KING, Circuit Judge:

   Ammad Bashaun Perry was convicted of one count of witness tam-
pering, in violation of 18 U.S.C. § 1512(b)(3). On appeal, Perry con-
tends that there was insufficient evidence to support the verdict. He
also asserts that the district court erred both in denying his pretrial
motion to dismiss the charge because of prosecutorial vindictiveness
and in denying his motion for a new trial. For the reasons explained
below, we affirm.

                                  I.

                                  A.

   At about 12:30 a.m. on March 15, 2001, the police in Montgomery
County, Maryland, observed a blue Hyundai Elantra traveling at a
high rate of speed. Two officers from the Montgomery County Police
Department (the "MCPD"), John Cameron and Joseph Saunders,
stopped the vehicle and requested that the driver produce his license
and registration. The driver (subsequently identified as the defendant,
Perry) was unable to produce a license, but he did provide the officers
with the vehicle’s registration, in the name of Barbara Hawkins (sub-
sequently revealed to be Perry’s mother). In response to Cameron’s
questions, Perry stated that his name was Benjamin Franklin Moffitt
and that his date of birth was June 28, 1967.

   Perry provided the officers vague answers to inquiries regarding
his place of residence. Their suspicions aroused, the officers asked
Perry to step out of the car. Perry complied and consented to a search
of the vehicle. By this time, Officer John Mullaney, also of the
MCPD, had arrived on the scene to provide back-up support to Cam-
eron and Saunders. Cameron remained with Perry, while Mullaney
and Saunders searched the vehicle, finding a seven-inch knife in the
                        UNITED STATES v. PERRY                           3
glove compartment and a set of brass knuckles in the center console.
They then searched the vehicle’s trunk, where they located a metal
pipe (wrapped at one end in electrical tape "to make a handle"), a
wooden "shank" (a handmade sharp instrument), and a laundry dryer
sheet box containing a loaded .380 caliber handgun and extra ammu-
nition. The firearm’s serial number had been obliterated.

   Perry was placed under arrest and informed that he was being
charged with various weapons violations. Cameron and Saunders then
transported Perry to the Rockville District Police Station. During the
ride to the police station, Perry repeatedly requested that the officers
"get rid of the gun." He informed them that he would "give [them]
anybody’s name [they] want[ed] to know" if they would "throw away
the gun."

   Later that evening, Officers Cameron and Saunders transferred
Perry from the police station to the nearby Central Processing Unit,
where he was booked by Corporal Douglas Carranza. When Carranza
asked Perry for his name and date of birth, Perry again asserted that
his name was Benjamin Franklin Moffitt and that his date of birth was
June 28, 1967. He was then fingerprinted, and a database identifica-
tion system revealed Perry’s true identity, that his date of birth was
actually June 10, 1971, and that he had a prior felony conviction. In
early June of 2001, once the MCPD became aware of his true identity
and his prior felony conviction, it referred Perry’s case to the United
States Attorney and the Bureau of Alcohol, Tobacco, and Firearms
(the "ATF") for possible federal prosecution.1

                                    B.

   On June 6, 2001, a grand jury in the District of Maryland returned
a two-count indictment against Perry. The indictment charged Perry
with being a felon in possession of a firearm, in violation of 18 U.S.C.
  1
   Under the evidence, the standard practice of the MCPD is to check the
criminal history of all persons arrested for firearms offenses, utilizing
name and date of birth, in order to identify any that are felons. Once such
an individual is identified, an Assistant State’s Attorney decides whether
that person’s case should be referred to the United States Attorney and
the ATF.

                2
§ 922(g)(1), and with knowingly possessing a firearm bearing an
obliterated serial number, in violation of 18 U.S.C. § 922(k).3 A jury
trial was conducted from April 9 to April 12, 2002. On April 12, after
nearly two days of deliberations, the court granted Perry’s unopposed
motion for a mistrial, on the ground that the jury was deadlocked.

   Soon thereafter, on May 1, 2002, a second grand jury returned a
three-count superseding indictment against Perry. In addition to the
charges made in the initial indictment, the grand jury alleged that
Perry had engaged in federal witness tampering, in violation of 18
U.S.C. § 1512(b)(3), when he provided a false name and false date of
birth to the MCPD.4 The defense moved to dismiss the witness tam-
pering count, contending that the indictment failed to allege an
offense under § 1512(b)(3), and asserting that the circumstances lead-
ing to the additional charge gave rise to a presumption of prosecu-
torial vindictiveness. The court denied the motion on May 13, 2002,
and Perry’s second trial began the next day. Following the Govern-
ment’s presentation of its case-in-chief, Perry moved for judgment of
acquittal on all counts. The court denied the motion as to the firearms
    2
     Section 922(g)(1) of Title 18 provides in pertinent part:
        It shall be unlawful for any person . . . who has been convicted
        in any court of, a crime punishable by imprisonment for a term
        exceeding one year [to] possess in or affecting commerce, any
        firearm or ammunition . . . .
18 U.S.C. § 922(g)(1).
   3
     Section 922(k) of Title 18 is violated when a "person knowingly . . .
transport[s] . . . in interstate or foreign commerce, any firearm which has
had the importer’s or manufacturer’s serial number removed, obliterated,
or altered." 18 U.S.C. § 922(k).
   4
     Section 1512(b)(3) of Title 18 provides in relevant part:
        Whoever knowingly . . . engages in misleading conduct toward
        another person, with intent to . . . hinder, delay, or prevent the
        communication to a law enforcement officer or judge of the
        United States of information relating to the commission or possi-
        ble commission of a Federal offense . . . shall be fined under this
        title or imprisoned not more than ten years, or both.
18 U.S.C. § 1512(b)(3).

charges, but reserved ruling on the witness tampering charge. Perry
renewed his motion for judgment of acquittal on all counts at the
close of the evidence. Again, the court denied the motion as to the
firearms charges, but reserved ruling on the witness tampering charge.
On May 16, 2002, the jury acquitted Perry on the two firearms
offenses, but it convicted him of witness tampering.

   On June 19, 2002, Perry again moved for judgment of acquittal, or
in the alternative, for a new trial. The court denied both motions.
Perry was subsequently sentenced to twenty-one months’ imprison-
ment, to be followed by three years of supervised release. Perry has
appealed, and we possess jurisdiction pursuant to 28 U.S.C. § 1291.

                                   II.

   In reviewing the sufficiency of evidence in a criminal case, a guilty
verdict must be upheld if there is substantial evidence, taking the view
most favorable to the prosecution, to support it. Glasser v. United
States, 

, 80 (1942); see also United States v. Bennafield,

, 324 (4th Cir. 2002). In conducting such an inquiry, we
may not "weigh the evidence or review the credibility of the wit-
nesses." United States v. Wilson, 

, 234 (4th Cir. 1997).
And, where the evidence supports differing reasonable interpretations,
"the jury decides which interpretation to believe."

   We review for abuse of discretion a district court’s denial of a
motion for a new trial. United States v. Arrington, 

,
1486 (4th Cir. 1985). We have observed that a court "should exercise
its discretion to grant a new trial ‘sparingly,’" and that it should do
so "‘only when the evidence weighs heavily against the verdict.’" Wil-

(quoting

   Finally, we review for abuse of discretion a court’s determination
of whether, in the circumstances of a particular case, a presumption

   The court ruled that only the § 922(g)(1) offense (felon in possession
of a firearm), and not the § 922(k) offense (possession of a firearm with
an obliterated serial number), could serve as a predicate offense for the
witness tampering charge.
6                       UNITED STATES v. PERRY
of prosecutorial vindictiveness is warranted. United States v. Najjar,

, 480 (4th Cir. 2002). In our review of such a determina-
tion, we are mindful that the presumption arises "‘only in cases in
which a reasonable likelihood of vindictiveness exists.’" 

(quoting United States v. Goodwin, 

, 372 (1982)).

                                   III.

   Perry raises three challenges to his federal witness tampering con-
viction. First, he contends that there was insufficient evidence on
which to convict him of violating § 1512(b)(3). Next, Perry maintains
that the court abused its discretion in denying his motion for a new
trial. Finally, he asserts that the court erred in failing to dismiss the
witness tampering charge as motivated by prosecutorial vindictive-
ness. We address each contention in turn.

                                   A.

   Perry first maintains that the evidence was insufficient to support
his conviction of witness tampering.6 In particular, he asserts that the
prosecution’s evidence failed to establish that, in providing the
MCPD with a false name and a false date of birth, he intended to pre-
vent the communication of information to federal law enforcement
officers relating to the possible commission of a federal offense.

   In order to secure a guilty verdict under § 1512(b)(3), the Govern-
ment is obliged to demonstrate that a defendant knowingly (1) "en-
gage[d] in misleading conduct toward another person," (2) with the
intent to "hinder, delay, or prevent the communication to a [federal]
law enforcement officer . . . of information relating to the commission
or possible commission of a Federal offense." 18 U.S.C. § 1512(b)(3).
Perry contends that, while the evidence may have shown that he
    6
    The Government contends that Perry’s challenge to the sufficiency of
the evidence is actually a "poorly-disguised attack[ ] on the unobjected-
to jury instructions," which we should review for plain error. Perry, how-
ever, has framed his challenge as one to the sufficiency of the evidence,
and we therefore review it as such, "assum[ing] that the jury was cor-
rectly instructed." United States v. Baldyga, 

, 679 n.3 (1st
Cir. 2000).
                         UNITED STATES v. PERRY                            7
engaged in misleading conduct, it failed to demonstrate that he did so
with an intent to hinder, delay, or prevent any communication with a
federal law enforcement officer regarding a possible federal offense.

   Jurisdiction for a federal prosecution under § 1512(b)(3) "is based
on the federal interest of protecting the integrity of potential federal
investigations by ensuring that transfers of information to federal law
enforcement . . . relating to the possible commission of federal
offenses be truthful and unimpeded." United States v. Veal, 

, 1250 (11th Cir. 1998); see also United States v. Applewhaite,

, 688 (3d Cir. 1999) ("It is the integrity of the process,
and the safety of those involved in it that Congress was seeking to
protect in enacting § 1512."). Although a defendant must have
engaged in misleading conduct with the intent to "hinder, delay, or
prevent" communication with a federal law enforcement officer, the
statute makes clear that "no state of mind need be proved with respect
to the circumstance . . . that the law enforcement officer is an officer
or employee of the Federal Government." 18 U.S.C. § 1512(g)(2). As
the Third Circuit has observed, the statute instead requires only "that
the government establish that the defendants had the intent to influ-
ence an investigation that happened to be federal." 

; see also United States v. Baldyga, 

, 681 (1st
Cir. 2000) (same); United States v. Causey, 

, 422 (5th
Cir. 1999) (concluding that statute requires "proof that officers with
whom the defendant believed the victim might communicate would
in fact be federal officers" (emphasis in original) (internal quotation
marks omitted)).7
  7
    The Eleventh Circuit appears to have gone a step further, observing
that § 1512(b)(3) only requires proof that a defendant intended to influ-
ence an investigation and there was a "possibility or likelihood that . . .
false and misleading information would be transferred to federal authori-
ties irrespective of the governmental authority represented by the initial
investigators." 

. In Veal, the court concluded
that, even if a defendant’s intent was to influence a state investigation,
the federal statute was satisfied so long as there existed a possibility that
the misleading information would be transferred to federal law enforce-
ment officers. We need not decide whether to adopt this interpretation of
§ 1512(b)(3), because there was sufficient evidence here to show that
Perry intended, in misleading the MCPD, to "influence an investigation
that happened to be federal." 

.
8                       UNITED STATES v. PERRY
   The Government presented ample evidence from which a jury
could conclude that Perry’s intent was to hinder, delay, or prevent
communications related to "an investigation that happened to be fed-
eral," specifically, the federal investigation into Perry’s status as a
felon in possession of a firearm. The jury heard testimony that Perry
pleaded with Officers Cameron and Saunders to "get rid of the gun."
It also heard that Perry provided false information to Corporal Car-
ranza during the booking process. The jury was entitled to conclude
that Perry provided such false information with an intent to prevent
the MCPD from communicating his true identity to those who might
investigate the firearms offenses. Moreover, under the evidence, once
Perry’s true identity was discovered, his file was referred to the
United States Attorney and the ATF for possible federal prosecution.8
Whether Perry was aware that a portion of the firearms investigation
would be federal is irrelevant: the prosecution need only show (1) that
Perry provided false information with the intent to influence the fire-
arms investigation, and (2) that the firearms investigation happened
to be federal. See 

; 

. Accordingly, the evidence was sufficient for the jury to find
that Perry had violated § 1512(b)(3).9
    8
     As discussed above, the legislative purpose behind § 1512(b)(3) is to
ensure that communications with federal law enforcement relating to the
possible commission of federal crimes "be truthful and unimpeded."

. As the evidence demonstrated, the MCPD regu-
larly communicated with federal authorities regarding felons who were
arrested for firearms offenses. Accordingly, the jury was entitled to con-
clude that, had Perry’s true name and date of birth gone undetected, he
would have successfully hindered the MCPD’s communication with fed-
eral officials regarding possible federal crimes — conduct the statute is
designed to prevent.
   9
     Perry also contends that the Government, in order to obtain a convic-
tion under § 1512(b)(3), was required to show that the MCPD was, at the
time of the arrest, cooperating in an ongoing federal investigation or in
the investigation of a federal offense. This contention is without merit.
Nothing in § 1512(b)(3) suggests that the recipient of the deceptive infor-
mation must be involved in an ongoing federal investigation, or in an
investigation of a federal crime. Indeed, as the First Circuit observed in
rejecting a similar contention, the statute "does not require that the wit-
ness’s communication with federal officers be . . . imminent." 

.
                        UNITED STATES v. PERRY                           9
                                    B.

   Perry next maintains that the district court abused its discretion
when it denied him a new trial on the basis of an inconsistent verdict.
Pursuant to Rule 33 of the Federal Rules of Criminal Procedure, a
court may, on a motion by the defendant, grant a new trial "if the
interest of justice so requires." Fed. R. Crim. P. 33. In this situation,
the court was well within its discretion in deciding that the interest of
justice did not so require. First, assuming the verdict was inconsistent,
"a defendant cannot challenge his conviction merely because it is
inconsistent with a jury’s verdict of acquittal on another count."
United States v. Thomas, 

, 40 (4th Cir. 1990) (citing
United States v. Powell, 

(1984)). Perry contends, how-
ever, that the inconsistency likely evinces jury confusion due to
improper instructions and a faulty verdict sheet.10 He asserts that the
instructions and the verdict sheet permitted the jury to convict him of
the § 1512(b)(3) offense if the jury found that he engaged in mislead-
ing conduct to "hinder, delay, or prevent" a police investigation of any
type, rather than solely a federal investigation. We disagree.

   The instructions were clear that, in order to convict under
§ 1512(b)(3), the jury was required to find that, when Perry provided
the MCPD with a false name and a false date of birth, he intended to

   We also decline to adopt Perry’s suggestion that we read § 1512(b)(3)
to require that federal officials actually receive the misleading informa-
tion. The statute itself applies to one who engages in misleading conduct
with an intent to "hinder, delay, or prevent" communication with federal
law enforcement officers. It does not require that the individual have suc-
ceeded. Accordingly, this challenge to Perry’s conviction is likewise
meritless.
   10
      Because Perry did not properly object to the instructions or verdict
sheet, were he to challenge their propriety directly, we would review
only for plain error. See United States v. Nicolaou, 

, 569
(4th Cir. 1999). Perry instead asserts that the court erred in refusing to
award him a new trial, since the inconsistent verdict was likely the result
of improper instructions and an improper verdict sheet. This challenge
was properly raised below, and we thus review for abuse of discretion.
See 

.
10                       UNITED STATES v. PERRY
prevent it "from communicating with agents of the [ATF] and the
United States Department of Justice and judges of the United States
of America information relating to the commission and possible com-
mission of a . . . [f]irearm offense committed in violation of Title 18,
United States Code Section 922(g)." J.A. 194. Throughout the instruc-
tions, the court reiterated the requirement that the communication
Perry intended to prevent must have related to a federal offense.11
Because we are unable to discern any incorrect statement of law in
the instructions, the court did not abuse its discretion in declining to
award a new trial on this basis.

   Perry also asserts that the verdict sheet was improper because it
described the § 1512(b)(3) offense as "[e]ngaging in misleading con-
duct with intent to hinder, delay or prevent a police investigation."
Perry contends that this description was erroneous because it permit-
ted the jury to convict him on the basis of a finding that he provided
false information to influence a traffic investigation. The court, how-
ever, made clear in its instructions that the predicate investigation
must be federal. Specifically, it instructed the jury that Perry must
have intended to prevent the MCPD "from communication to agents
of the ATF [about a] [f]irearm offense committed in violation of Title
18, United States Code Section 922(g)." Accordingly, viewing the
verdict sheet and the instructions as a whole, we discern no error. See
United States v. Brown, 

(8th Cir. 2003) (concluding
that "jury instructions and verdict form viewed as a whole did not
allow the jury to convict" the defendant of charge different than that
  11
    In its instructions, the court emphasized that, in order to convict
Perry under § 1512(b)(3), the jury was obliged to find that the communi-
cation that Perry intended to hinder, delay, or prevent related to the pos-
sible commission of a federal offense. See, e.g., J.A. 195 ("In order to
prove the defendant guilty of [witness tampering], the Government must
prove . . . the defendant acted . . . with intent to hinder, delay or prevent
the communication to a [federal law enforcement officer] information
related to the commission or possible commission of a federal offense."
(emphasis added); J.A. 196-197 ("The Government must prove that the
defendant intended . . . to hinder, delay or prevent the communication of
information as to his identity to a law enforcement officer or judge as
that information related to the commission or possible commission of
[the federal offense of] unlawful possession of a firearm by a person who
had previously been convicted of a [felony].").
                         UNITED STATES v. PERRY                          11
contained in indictment); United States v. Poirier, 

,
1032 (11th Cir. 2003) ("On appeal, we examine whether the jury
instructions and verdict form, considered as a whole, were sufficient
so that the jurors understood the issues and were not misled." (internal
quotation marks omitted)).12

                                    C.

   Finally, Perry contends that a presumption of prosecutorial vindic-
tiveness arose when the Government added a witness tampering
charge in the superseding indictment after Perry exercised his right to
seek a mistrial. The Government responds that no such presumption
is warranted when, as here, a mistrial is declared (1) without opposi-
tion, and (2) merely as a result of a deadlocked jury.

   A defendant’s right to due process "requires that there be no vin-
dictiveness against [him] for having chosen to exercise [his] constitu-
tional rights." United States v. Whaley, 

, 1477 (7th Cir.
1987) abrogated on other grounds as recognized in United States v.
Durrive, 

, 1228 (7th Cir. 1990) (citing North Carolina
v. Pearce, 

, 723-25 (1969)). Because motives are often
"difficult to prove," the Supreme Court has determined that, "in cer-
tain cases in which action detrimental to the defendant has been taken
after the exercise of a legal right . . . it [is] necessary to ‘presume’ an
improper vindictive motive." 

. Such a pre-
sumption, however, is only warranted "in cases in which a reasonable
likelihood of vindictiveness exists." 

presumption of prosecutorial vindictiveness is gener-
ally warranted only in a post-conviction setting, such as when a
defendant successfully attacks his conviction on appeal, and then
receives a harsher sentence on retrial. See 

.
Courts have been extremely cautious in applying the presumption in
the pretrial context. For example, the Supreme Court has held that a
  12
     Perry also asserts that the court erred in denying his motion for a new
trial because the verdict was against the weight of the evidence. As dis-

, Part III.A, the evidence supports a conviction on the
§ 1512(b)(3) charge, and accordingly, the court did not abuse its discre-
tion in denying Perry a new trial on this basis.
12                      UNITED STATES v. PERRY
presumption of prosecutorial vindictiveness does not arise when the
Government carries out a threat, made during plea negotiations, to file
additional charges against an accused who declines to plead guilty.
Bordenkircher v. Hayes, 

, 363 (1978). Accordingly, we
must assess whether the lodging of a new charge following an unop-
posed mistrial resulting from a deadlocked jury is more akin to the
post-trial or the pre-trial prosecutorial vindictiveness decisions. In this
regard, the Seventh Circuit has recognized that a post-mistrial charg-
ing decision "seems to fall between the pretrial-postconviction dichot-
omy established by the Supreme Court." 

.

   In determining whether a presumption of vindictiveness may
appropriately be applied in the mistrial setting, we must look to the
basis for the mistrial. 

case, the mistrial resulted from a jury
deadlock. And we have observed that there is "no realistic likelihood
of vindictiveness . . . when a jury is deadlocked and both parties agree
that a declaration of mistrial is a necessity." United States v. Fiel, 

, 1007-08 (4th Cir. 1994) (quoting 

-
79); see also United States v. Khan, 

, 32-33 (2d Cir.
1986); United States v. Mays, 

, 1190 (11th Cir. 1984).
As the Eleventh Circuit has observed, the prosecutorial vindictiveness
presumption is rooted in the notion that a defendant may not be pun-
ished for the exercise of his rights. 

. Because
the unopposed mistrial resulting from the deadlocked jury did not
arise from Perry’s exercise of a protected right, but rather was based
on trial events largely beyond his control, there is no reason to pre-
sume that the United States Attorney was "punishing" Perry by filing
a new charge against him.13 Under such circumstances, no "reason-
  13
    Because Perry’s motion for a mistrial was unopposed, we need not
reach the question of whether such a presumption might be warranted
when the Government opposes such a motion. See United States v. Mot-
