Given his strange history of shady operations, I thought he might have been an intelligence agent who volunteered to be a willing diversion for the FBI. Playing the part of the wronged Richard Jewell type guy, in an effort to get the real culprits to reveal more about themselves.
I thought they were pretending he was a serious suspect and he was pretending to be pissed off about it. I now think it is more likely that I was pretending to have a clever grasp on their game that I clearly do not possess.
I now admit I don't know what the hell to think about him. He has a very interesting background, to say the least.
