Seriously? People have died from less injuries than Zimmerman had. And if you take Zims word (no evidence saying otherwise), when he was trying to get onto the grass (grass stains on his jacket proved this to be true) it revealed his gun. At this point Martin reached for his gun threatening to use it. Even if that wasn’t true, it is entirely possible and likely that Martin was going to beat him to death. Slim to none is far from the truth.
Even if he didn’t die, is he supposed to live his life completely brain dead just so this thug could live to do this again next time… or possible kill someone next time? I don’t care if he was black, white, blue, red, etc… when he made the choice to be a thug and start beating up on an older man, he should have weighed the consequences of the outcome. Yes it sucks that someone died, but why should Zim have been the one dead???
