Texas Penal Code - PENAL § 8.06. Entrapment

(a) It is a defense to prosecution that the actor engaged in the conduct charged because he was induced to do so by a law enforcement agent using persuasion or other means likely to cause persons to commit the offense. Conduct merely affording a person an opportunity to commit an offense does not constitute entrapment.

(b) In this section “law enforcement agent” includes personnel of the state and local law enforcement agencies as well as of the United States and any person acting in accordance with instructions from such agents.
