You also can't discern when the person is no longer a reasonable threat so quickly. Pretty sure we've seen a cat that everyone thought got slept get up and mollywop a muhfucka by surprise 'cause he turned his back. Nope, he's good up to dropping that first stomp. That's where he went wrong.
HOWEVER...
Under North Carolina's self defense laws he had every right to actually kill the tranny if he claimed he felt it necessary for his own self preservation. After all those threats and shit dude would have been well within his rights to put a bullet in the tranny's head because NC allows deadly force as a self defense response, so there's a bit of a gray area here that his legal defense can maneuver to get him off. If he could have pulled out the biscuit and shot the tranny, then there may be legal room for them head stomps.
My nigga I don't think you understand the law. Good luck to that nigga trying to prove that his life was in danger from an unresponsive person taking repeated unguarded punches to the face all while people in the background are saying "Daaaaamn, he's sleep, he's sleep." Any lawyer that can then convince a jury that the subsequent stomps to the face were also necessary will be worth his weight in platinum. There isn't a stand your ground law in the country that let's you pull out a gun and shoot an unconscious person. I don't know what shit you're smoking, but it's good.
