Actus Reus
The act required to commit a given crime
A required component of every common law crime, along with mens rea
Actus Reus - Requirement
Voluntary Physical Act

A failure to act can constitute actus reus if:
1) D had a specific legal duty to act;
2) D had knowledge of facts giving rise to the duty; and
3) It was reasonably possible for D to perform the duty
Mens Rea - General
The mental element required at the time a crime was committed; a required element of common law crimes
Mens Rea - Forms of MR (3)
