Is entrapment a crime where the idea of committing a crime originates with law enforcement officers or their agents?

Where the idea of committing a crime originates with law enforcement officers or their agents, and a person has no previous intent or purpose to violate the law but is induced or persuaded by them to commit a crime, he is a victim of entrapment. In such cases the law, as a matter of policy, forbids his conviction. However, where a person already has the readiness and willingness to break the law, the mere fact that government agents provide what appears to be a favorable opportunity to commit a crime is not entrapment. See Notaro v. United States, 363 F.2d 169 (9th Cir. 1966).
