Hampton v. United States, 425 U.S. 484 (1976), is a United States Supreme Court decision on the subject of Entrapment. By a 5–3 margin, the Court upheld the conviction of a Missouri man for selling heroin even though all the drug sold was supplied to him, he claimed, by a Drug Enforcement Administration informant who had, in turn, gotten it from the DEA. The majority held that the record showed Hampton was predisposed to sell drugs no matter his source.
