Williams v. United States

Issue: (1) Whether sequential drug transactions over a short time frame are "committed on occasions different from one another" for purposes of the Armed Career Criminal Act when the same undercover law enforcement officer repeatedly bought personal-use amounts of a controlled substance from a suspect; and (2) whether, in the absence of an appeal waiver as part of a plea agreement, a prosecutor"s increased sentencing recommendation and a district court"s imposition of a longer sentence following a defendant"s attempt to preserve objections to a presentence investigation report amount to prosecutorial or judicial vindictiveness, or whether the more onerous recommendation and sentence are legitimate responses to the defendant"s purported failure to accept responsibility for his offense.
