We do agree on enough physical fact to establish that Zimmerman acted improperly, and started the fight, and shot the kid. We know, for example, that Zimmerman got out of his vehicle, armed. At that point Martin was being threatened with serious harm - when an angry looking guy follows you down the street at night in his truck, catches you alone, and gets out of the truck, you are in a fight or flight situation: either one justified. Martin was near home, which means he was cornered: if he had run home he would have lead the creep to his house, the guy would know where he lived. We also know that Zimmerman followed the kid because Zimmerman thought he was up to no good, and so strongly resembled criminals afflicting the area that he was worth following with difficulty - the only basis for that was Martin's race, since he resembled those criminals in no other significant way (they did not work alone, they did not operate in the rain, they did not generally operate on foot, etc etc etc). And we know that Zimmerman brought the gun with him on purpose, despite its weight and general inconvenience when following someone, and therefore was anticipating confrontation when he got out of the truck. He did not bring his phone, apparently, or at least did not have it handy (?) - so keeping the police apprised of his own or Martin's location was not foremost on his agenda. So we have racist presumption, negligence, and confrontational threat by Zimmerman, leading directly to him shooting someone. We know this, we are agreed on this. So if you find "nigger hunt" objectionable, we can probably find another term - but it's not going to be judgment free and accurate both.
