People v. Bardsley

Defendant was convicted, after bench trial, of aggravated assault of a private security officer. Self-defense, as a defense to assault and derivative offenses, is an affirmative defense that a defendant forfeits by not raising. State's presentation of evidence sufficient to allow a defendant to raise the defense does not ipso facto raise the defense; a defendant must explicitly raise the defense to avoid forfeiture.(JORGENSEN and SCHOSTOK, concurring.)
