MEMORANDUM *

Stanley Ackerman appeals the district court’s denial of his motion to suppress and his motions for judgment of acquittal, and the district court’s refusal to make a downward adjustment in his sentence for acceptance of responsibility. Because the facts are known to the parties, we do not recite them here. We affirm.

1. Denial of Motion to Suppress Statement

Ackerman argues that the district court erred1 in refusing to suppress his statement to law enforcement. “Coercive po-lic[e] activity is a necessary predicate to finding a confession involuntary.”2 There is no evidence that the officer engaged in any coercive activity in this case, thereby distinguishing it from Mincey v. Arizona.3 The district court’s determination that the officers’ account of the brief interaction with Ackerman was credible is not clearly erroneous. Therefore, Ackerman cannot prevail on this claim.

II. Denial of Motions for Judgment of Acquittal

Viewing the evidence in the light most favorable to the Government, we conclude that a rational jury could have found that Ackerman was driving at the time of the accident.4 The Government presented plausible evidence that Ackerman was driving. The testimony from Dr. Lee and law enforcement personnel conflicted. The jury reasonably could have chosen to reject Dr. Lee’s testimony, particularly because he did not account for why Acker-man was found in the driver’s seat. Therefore, the district court did not err5 in allowing this case to go to the jury.

*228III. Refusal to Make a Downward Adjustment for Acceptance of Responsibility

The district court’s factual findings support its conclusion that Ackerman failed to clearly demonstrate acceptance of responsibility.6 The district court determined that Ackerman had made inconsistent statements about who was driving immediately after the accident. Further, the district court determined that overwhelming physical and medical evidence suggested that Ackerman was driving and that neither of the other occupants of the vehicle would have been able to switch places with him after the accident. These findings were proper and certainly not clearly erroneous.7

Ackerman argues that he was entitled to an acceptance of responsibility adjustment because he had no memory of the accident. He relies upon the commentary to United States Sentencing Guideline § 3E1.1 that states “[i]n rare situations a defendant may clearly demonstrate acceptance of responsibility ... even though he exercises his constitutional right to trial.”8 However, the commentary also states that, in such situations, “a determination that a defendant has accepted responsibility will be based primarily upon pre-trial statements and conduct.”9 The district court considered Ackerman’s pretrial statements and conduct and determined that he made inconsistent statements. Thus, Acker-man’s pretrial statements and conduct did not clearly demonstrate acceptance of responsibility. Indeed, the only conduct that showed any real acceptance of responsibility was the letter Ackerman wrote several months after the verdict. Given these factual circumstances, the district court’s determination that this letter did not' clearly demonstrate acceptance of responsibility was proper and is not an abuse of discretion.

Neither United States v. Cortes10 nor United States v. Ochoa-Gaytan11 assist Ackerman’s argument because those cases turned on the fact that the district court had not exercised its discretion.12 In this case, it is clear that the district court recognized and exercised its discretion; it just chose not to do so in favor of Acker-man. It did not err.

AFFIRMED.
