Aid and abet

help someone commit a crime; assist someone

"To assist the perpetrator of the crime while sharing in the requisite intent." United States v. Martinez, 555 F.2d 1269, 1271 (5th Cir. 1977).To sustain a conviction for aiding and abetting, the Martinez court noted that the evidence must show that defendant was associated with the criminal venture, participated in it as something he wished to bring about, and sought by his action to make it succeed.Under the concept of aiding and abetting, it is not necessary for the government to show that a defendant himself physically committed the crime with which he is charged in order for the government to sustain its burden of proof. A person who aids or abets another to commit an offense is just as guilty of that offense as if he committed it himself.
