OPINION
Tony Wade Johnson appeals from his conviction for violating 18 U.S.C. § 922(g)(1), which prohibits the possession of a firearm by a convicted felon. He contends that the government transgressed the Double Jeopardy Clause of the United States Constitution, U.S. CONST, amend. V, by prosecuting him a second time for the same offense after a mistrial was declared in his first trial. Johnson also challenges the sufficiency of the government’s evidence against him. Finding no error, we affirm Johnson’s conviction.
I.
At approximately 3:30 p.m. on April 25, 1993, appellant Tony Wade Johnson was observed driving a car by municipal police officers William Frederick and Reid King. At the time, the officers were sitting in an unmarked patrol car within the city limits of Sanford, North Carolina. .Officer Frederick knew Johnson’s identity and was aware that he did not have a valid North Carolina driver’s license.
The officers attempted to pull Johnson over, following his vehicle at a distance of about one car length for approximately three-tenths of a mile. Travelling between 25 and 35 miles per hour, Johnson turned into the parking lot of “J & J Grocery” and drove around to the back of the store. The police officers continued to follow Johnson closely and observed him toss a dark object out of the driver’s window with his left hand. Johnson then stopped his vehicle elsewhere in the parking lot. Officer King went to the area behind the building where he and Officer Frederick had seen Johnson drop the object and discovered a small, black .38 caliber revolver. A search of Johnson’s car revealed nothing of significance.
On February 1, 1994, a grand jury sitting in the United States District Court for the Middle District of North Carolina indicted Johnson on one count of possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1). In 1990, Johnson had been convicted in North Carolina state court of being an accessory after the fact to murder. The federal case was tried on April li-li, 1994. At the urging of defense counsel, the parties stipulated in writing that Johnson previously had been convicted of a crime punishable by more than one year, agreeing not to inform the jury further because of the prejudicial nature of that offense. During its instructions to the jury regarding Johnson’s prior felony conviction, the court read from the indictment that Johnson had been convicted of being an accessory after the fact to murder. After the jury began deliberating, the court informed Johnson that it would grant a motion for a mistrial, but only if the request was made before the jury returned with a verdict. Johnson then asked for a mistrial, and the court granted his motion.
Prior to his second trial, and before a different district court judge, Johnson moved *978 to dismiss the indictment against him based on the constitutional prohibition against double jeopardy. The district court denied the motion, reasoning that Johnson had sought mistrial voluntarily. The court also determined that the judge in the prior proceeding had demonstrated “an abundance of fairness” in responding to the inadvertent reading from the bill of indictment information that had been excluded by stipulation of the parties. 1 The matter proceeded to trial on May 12. The jury found Johnson guilty of violating § 922(g)(1). The defendant moved for'a judgment of acquittal. The court denied the motion and sentenced him to 264 months in prison. Johnson filed timely notice of appeal to this court.
II.
Johnson first claims that the district court erred by denying his motion to dismiss the indictment against him, arguing that his retrial violated the Fifth Amendment’s prohibition against double jeopardy. He contends that he did not waive a challenge to his reprosecution by moving for mistrial at the initial proceeding, because he was given the “Hobson’s choice” of moving for mistrial before the jury returned with a verdict or accepting the court’s prejudicial jury instruction.
As we stated in
United States v. Borromeo,
We have recognized that a “court’s finding concerning the prosecutor’s intent is, of course, a factual one which we must accept unless it is clearly erroneous.”
Borromeo,
Prior to Johnson’s second trial, the district court found no evidence of bad faith on the part of the United States Attorney or the original trial judge in this case, and we find nothing in the record to contradict that determination. The prosecution had entered into a mutually agreeable stipulation to keep the nature of Johnson’s prior conviction from the jury and played no role in bringing about the prejudicial jury instruction. The judge presiding over Johnson’s first trial, who articulated the belief that his instruction would stand on appeal, nonetheless expressed concern about his mistake and offered the defendant the opportunity to request a mistrial. In sum, the record strongly supports the district court’s finding prior to Johnson’s second trial that there was no prosecutorial or judicial intent to provoke a mistrial. This case, therefore, falls outside the exception established in Kennedy.
In granting Johnson’s motion for a mistrial, the court specifically asked the defendant: “You understand that the granting of a mistrial in no way prohibits or limits the retrial of this case at a later time, is that correct?” *979 Johnson, duly represented by counsel, then responded ‘Tes.” In the absence of governmental conduct designed to induce a mistrial, Johnson thereby waived the possibility of raising a meritorious double jeopardy claim. 2
III.
In reviewing a sufficiency of the evidence challenge to a conviction, we inquire whether
“any
rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt,”
Jackson v. Virginia,
Johnson challenges the sufficiency of the government’s evidence against him on several grounds. First, he attacks the credibility of the prosecution’s witnesses by citing what he contends are inconsistencies in their testimony. In particular, he points to alleged contradictions and omissions in the testimony of police officers Frederick and King. These include the positions of various vehicles at the scene and whether Johnson’s car was searched before or after King went to the area where Johnson’s revolver was discovered. The “discrepancies” cited by Johnson are relatively minor; no one seriously disagreed about any facts of significance, except for Johnson’s claim that he did not toss the firearm from his car window. More importantly, assessing the credibility of witnesses is within the province of the jury — a task in which we decline to engage at this stage of proceedings, particularly when the alleged inconsistencies in their testimony concern relatively unimportant points.
See Giunta,
Next, Johnson focuses his insufficient evidence claim on two particular elements of the § 922(g)(1) offense: (1) possession of a firearm (2) transported in interstate commerce. Regarding the possession issue, Johnson relies on
United States v. Blue,
Regarding the statute’s interstate commerce requirement, Special Agent Ernest Driver of the Bureau of Alcohol, Tobacco, and Firearms testified that the weapon in question was manufactured by the Rossi Company in Brazil and imported into the United States by the Garcia Corporation in Washington, D.C. By definition, a firearm that arrives from abroad in Washington, *980 D.C., and ends up in North Carolina must have travelled through interstate commerce.
IV.
Because Johnson’s second trial did not violate the proscription against placing him twice in jeopardy for the same offense, and because there was sufficient evidence to support the jury’s verdict against him, Johnson’s conviction is hereby
AFFIRMED.
Notes
. Alleging insufficient evidence, Johnson also made a pre-trial motion for a judgment of acquittal, which the district court likewise denied.
. Because Johnson waived any colorable claim of doable jeopardy that might have prevented his retrial, arguments regarding the sufficiency of the evidence at his first trial are immaterial.
