So answer this if you please. If Martin were so fearful as you claim and we have no way of knowing because of the unfortunate events of that evening, why didn't he just go home? There is ZERO evidence that Zimmerman chased him down. None whatsoever.
Based on the timelines that I have seen, if Martin were afraid, he had plenty of opportunity to go home. In fact, had he gone home right from the 7-11 he would have never crossed paths with Zimmerman.
Now before you get all up in arms, I am not saying that not going straight home from 7-11 means Martin deserved to die. I am merely pointing out that if you can speculate on what ifs and posture things that Zimmerman should have done differently, then surely in the interest of fairness you can do the same for Martin no?
