§ 40.05 Entrapment.
In any prosecution for an offense, it is an affirmative
defense that the defendant engaged in the proscribed conduct
because he was induced or encouraged to do so by a public
servant, or by a person acting in cooperation with a public
servant, seeking to obtain evidence against him for purpose of
criminal prosecution, and when the methods used to obtain such
evidence were such as to create a substantial risk that the
offense would be committed by a person not otherwise disposed to
commit it. Inducement or encouragement to commit an offense
means active inducement or encouragement. Conduct merely
affording a person an opportunity to commit an offense does not
constitute entrapment.
