I'm calling it now: if this guy is as much of a /pol/tard as he seems to be, he is gonna try to embrace the 'fed made me do it' angle. He's probably cooked up bullshit schizo-MKUltra lore for himself. If he does, don't believe any of it.
He's just a failed mumble rapper who figured he'd just take the fast track to immediate, nationwide attention- even if it inevitably results in people seeing what a fucking loser he is. He 100% surrendered because he wants the additional attention from continued news coverage, future trials, etc.
