Entrapment

Entrapment is a practice in which a law enforcement agent or an agent of the state induces a person to commit a crime that the person would have otherwise been unlikely or unwilling to commit. In US law, it is defined as "the conception and planning of an offense by an officer or agent, and the procurement of its commission by one who would not have perpetrated it except for the trickery, persuasion or fraud of the officer or state agent".
