Oh but he might not have a choice. He accepted drug money to pay for his treatment. He is already a part of it. A lawyer would simply where did you think they were getting all of this money from? Then he can either say he was illegally gambling, or play stupid which no one would believe. I'm reading pretty far into that scenario though. I see that as a possibility though.
