Entrapment

An act by the police or their agents, such as informants, to induce a person to commit a crime for the purpose of prosecuting that person for that induced crime. If the judge or jury believes that the person was predisposed to commit the crime anyway, even when the government agent suggested the crime or even helped with its commission, they are unlikely to accept an entrapment defense. Entrapment defenses are difficult to mount for defendants with prior convictions.
