Maybe instead of arguing whether or not Zimmerman is a racist, we should be speculating on whether he is a bully, (he outweighed the kid by 110 lbs) or a coward (threatened by iced tea?) or a vigilante (the police told him to stop following this kid..)
Even more importantly, we should be arguing about what kind of law is so poorly written that it doesn't allow the police to distinguish between someone who was jumped and used lethal force to protect themselves, and somebody who picked a fight with a person, then claims he felt threatened, and shot the guy.
Not to mention wondering what would have happened if, by chance, Zimmerman had picked a fight with the kid but in the scuffle, Zimmerman had ended up dead. We don't actually have much doubt in our minds about that, do we? Martin would be in the klink.
