The standard common law test of criminal liability is expressed in the Latin phrase "actus reus non facit reum nisi mens sit rea", i.e. "the act is not culpable unless the mind is guilty". As a general rule, someone who acted without mental fault is not liable in criminal law. Exceptions are known as strict liability crimes. Moreover, when a person intends a harm, but because of bad aim or other cause, the intent is transferred from an intended victim to an unintended victim, the case is considered to be a matter of transferred intent.
