So, Z was supposed to lie there and think about whether his injuries were life threatening while Saint Trayvon was on top of him, and every time he punched him, he was supposed to add that punch to the total, until the sum total of his injuries became life threatening?
It's insane.
Self defense doesn’t require you to be half dead before fighting back. The reason the injuries weren’t as severe as they could have been is Z shooting Martin.
The injuries have nothing to do with it if Martin was onl top, having noticed the gun, was attempting to get the gun and was telling the “white-ass cracker” he was going to die. that would have defininely put GZ in fear for his life if he were a rational person. The injuries only serve to collaberate GZ’s story of what happened. If GZ knew Martin saw the gun and was going for it, he knew it was either himself or Martin who was going to die. Martin had already sucker punched him and taken him to the ground, on top of him pounding away.
