 In "United States v. Keenan", the accused was found guilty of murder after he obeyed an order to shoot and kill an elderly Vietnamese citizen.The Court of Military Appeals held that "the justification for acts done pursuant to orders does not exist if the order was of such a nature that a man of ordinary sense and understanding would know it to be illegal".The soldier who gave the order, Corporal Luczko, was acquitted by reason of insanity.
