Even more tinfoil - does not this guy's profile fit the assassin/patsy mold? Strong physically, good with a gun, intelligent, but anti-authoritarian with a screw loose. A lot of what he did was very mechanical.
It's good for someone to not take things at face value now-and-then. There is plenty of conformist thinking to spread around.
I personally think he wasn't a patsy. I think he felt persecuted, thanks to the race-baiters. So he decided to go 'black panther'.
