The federal statute for theft requires proof of mens rea to secure a conviction.
Professor Notes

Morissette v. United States is a landmark case that examines the relationship between mens rea, or intent, and criminal liability. The Supreme Court emphasized the importance of proving that a defendant possessed the requisite intent to commit a crime. In this case, Morissette's belief that the bomb casings were abandoned was crucial to determining whether he had the mens rea necessary for a conviction of theft. The Court's ruling reflects a broader legal principle that individuals should not be held criminally liable unless they acted with a guilty mind, underscoring the fundamental tenet of criminal law that intention matters. Additionally, the Court's analysis of statutory language suggests that unless Congress explicitly eliminates the mens rea requirement, courts must infer it in criminal statutes in the interest of justice.
