n. in criminal law, the act of law enforcement officers or government agents inducing or encouraging a person to commit a crime when the potential criminal expresses a desire not to go ahead. The key to entrapment is whether the idea for the commission or encouragement of the criminal act originated with the police or government agents instead of with the "criminal." Entrapment, if proved, is a defense to a criminal prosecution. The accused often claims entrapment in so-called "stings" in which undercover agents buy or sell narcotics, prostitutes' services or arrange to purchase goods believed to be stolen. The factual question is: Would Johnny Begood have purchased the drugs if not pressed by the narc?
