So Greger, by your formula Travis McMichael (and his father and interested neighbor who was part of the chase and filmed it) should go free too because Ahmaud Arbery tried to take his gun making it self defense. After all they just wanted to talk to him. Ask him why he was out jogging while black.
Nope, whole different ballgame. Black guy didn't see that white guy had a gun and start chasing him and trying to take it away.
