Missouri Revised Statutes Title XXXVIII. Crimes and Punishment; Peace Officers and Public Defenders § 562.066. Entrapment

1. The commission of acts which would otherwise constitute an offense is not criminal if the actor engaged in the prescribed conduct because he or she was entrapped by a law enforcement officer or a person acting in cooperation with such an officer.

2. An “entrapment” is perpetuated if a law enforcement officer or a person acting in cooperation with such an officer, for the purpose of obtaining evidence of the commission of an offense, solicits, encourages or otherwise induces another person to engage in conduct when he or she was not ready and willing to engage in such conduct.

3. The relief afforded by subsection 1 of this section is not available as to any crime which involves causing physical injury to or placing in danger of physical injury a person other than the person perpetrating the entrapment.

4. The defendant shall have the burden of injecting the issue of entrapment.
