You cannot say a confrontation was wrong if you don't fucking know why he was confronted! Holy shit, how is this such a tough concept for people to understand? This started off as clearly a racist asshole shooting a boy because he didn't like the look of him. Then we discover that, holy shit!, there might be some details missing like, oh let's see, a witness describing the boy beating the man on the ground. Now those who began with assumptions have shifted to, "well, OBVIOUSLY the guy started the fight so he's still a racist asshole who should go to jail!" The complete lack of self awareness is astonishing.
Keep assuming. You and the rest are 0 for 1 thus far. We don't know enough.
