Backun v. United States

Backun v. United States, 112 F.2d 635, 637 (4th Cir. 1940), is a criminal case that held that the mental element for complicity in a crime is that the accessory had knowledge that aiding or abetting would facilitate the criminal act of the principal, and did not require the accomplice have the same purpose as the principal. The case is contrasted with United States v. Peoni, which held the opposite.
