Harris v. New York

Harris (defendant) was arrested for selling drugs to an undercover officer. At trial, he testified in his own defense, and on cross-examination the prosecution used his earlier unwarned statements to challenge his credibility. The statements were never used in the prosecution's case-in-chief, and the jury was told they could only be used to assess Harris's credibility. Harris was convicted, and the New York Court of Appeals affirmed per curiam.
