The court filing includes a laundry list of potential defense strategies, including:
* Entrapment: If Hansen uses this defense, he will "assert that the government, or an agent thereof, actually induced the offenses". If Hansen chooses the entrapment defense, Hansen "may present evidence that he, Lee Leblanc, and others associated with his now-defunct firm of Mylo Enterprises were induced to commit the offenses through assurances by Allen Raymond, Chris Cupit, and an unknown “attorney,” that certain acts that he and his business were contracted to perform in November 2002 were completely legal."
* Derivative Entrapment: A related option is a "derivative entrapment defense", where Hansen would assert that "the government uses a private party as its agent." In this case, Hansen would "assert that the private parties which the government used as its agents were Allen Raymond, Chris Cupit, GOP Marketplace LLC, and an unknown “attorney.”"
* Entrapment by Estoppel: If Hansen opted for a "entrapment by estoppel" defense, he would seek to convince a jury: "(1) that a government official or officials (Messrs. Raymond, Cupit, GOP Marketplace LLC, and an unknown “attorney”) told him the acts he was being asked to perform were legal; (2) that he relied on their advice; (3) that his reliance was reasonable; and (4) that, given the reliance, prosecution would be unfair."
* Good Faith: For a "good faith" defense, Hansen would "assert that he was acting in good faith in committing" the phone jamming, and that "he had been assured by Messrs. Allen Raymond, Chris Cupit, and an unknown “attorney,” that certain acts that he and his business partner and employees were contracted to perform in November 2002 were completely legal."
