An entrapment defense is used when you have engaged in prohibited conduct because you were induced or encouraged to do so by a public servant or a confidential informant working for the police who was seeking to obtain evidence against you for a criminal prosecution. To raise the defense your criminal defense attorney must show that the methods utilized by the police or the confidential informant caused you to do something you would not have otherwise done. For an entrapment defense to be successful, you need to establish that you were induced or encouraged to commit a crime that you were not predisposed to commit.
