this court “must view the evidence in the light most favorable to the verdict to determine whether any rational trier of fact could have found each element of the crime beyond a reasonable doubt.” United States v. Berisha, 925 F.2d 791, 795 (5th Cir.1991).
The Supreme Court has in two famous cases explained the concept of “under color of law.” In United States v. Classic, 313 U.S. 299, 326, 61 S.Ct. 1031, 1043, 85 L.Ed. 1368 (1941), the court stated that “[mjisuse of power, possessed by virtue of state law and made possible only because the wrongdoer is clothed with the authority of state law, is action taken ‘under color of state law.” In Screws v. United States, 325 U.S. 91, 111, 65 S.Ct. 1031, 1040, 89 L.Ed. 1495 (1944), the court reaffirmed the Classic formula and stated more simply that “under ‘color’ of law means under ‘pretense’ of law.” The court in Screws also observed that “[a]cts of officers who undertake to perform their official duties are included whether they hew to the line of their authority or overstep it.” Id. However, “acts of officers in the ambit of their personal pursuits are plainly excluded.”
This court and other courts of appeals have made clear that whether a police' officer is acting under color of law does not depend on duty status at the time of the alleged violation. Delcambre v. Delcambre, 635 F.2d 407 (5th Cir.1981) (per curiam); Layne v. Sampley, 627 F.2d 12, 13 (6th Cir.1980). Nor does Screws mean that if officials act for purely personal reasons, they necessarily fail to act “under color of law.” Brown v. Miller, 631 F.2d 408 (5th Cir.1980); United States v. Davila, 704 F.2d 749 (5th Cir.1983). Rather, Screws held simply that individuals pursuing private aims and not acting by virtue of state authority are not acting under color of law purely because they are state officers. Brown, 631 F.2d at 411.
Tarpley argues that there is no evidence that he “misused power possessed by virtue of state law” or that his actions were “made possible only because” he was “clothed with state authority.” According to Tarpley, he was acting as a jealous husband, not as a police officer. He assaulted Vestal in' his own home under circumstances in which it was clear that the motive for his attack was the extra-marital affair. That he told Vestal that he was a police officer, the argument continues, does not suggest that he was purporting to act under official authority. He never threatened to arrest Vestal. Vestal already knew he was a cop.
We are not persuaded. There was sufficient evidence in the record from which a rational juror could conclude that Tarpley was acting under color of law. Tarpley did more than simply use his service weapon and identify himself as a police officer. At several points during his assault of Vestal, he claimed to have special authority for his actions by virtue of his official status. He claimed that he could kill Vestal because he was an officer of the law. Significantly, Tarpley summoned another police officer from the sheriffs station and identified him as a fellow officer and ally. The men then proceeded to run Vestal out of town in their squad car. The presence of police and the air of official authority pervaded the entire incident. Under these circumstances, we are unwilling to say that no rational juror could find that Tarpley acted under color of law.

The defendant also contends that he cannot be convicted on the conspiracy count after his alleged co-conspirator, Pena, was acquitted in the same proceeding. He cites United States v. Klein, 560 F.2d 1236, 1242 (5th Cir.1977), cert. denied, 434 U.S. 1073, 98 S.Ct. 1259, 55 L.Ed.2d 777 (1978), for the proposition that the conviction of only one defendant in a conspiracy prosecution will not be upheld if all other alleged co-conspirators are acquitted. Although this has long been the rule in this
