To aid and abet means to assist another person in the commission of a crime by words or conduct actively, knowingly, and intentionally. In a criminal offense, a person who aids and abets in a crime, participates in the commission of the crime by performing some overt act or by giving advice or encouragement. The person should be sharing the criminal intent of the person who actually commits the crime. However, it is not necessary for the aider and abettor to be physically present at the scene of the crime, or take part in the actual criminal offense. Under criminal law, an aider and abettor party to a crime will be criminally liable as a principal, an accessory before the fact, or an accessory after the fact.
