I'm not happy anyone is dead, especially a 17 year old kid but IMO Zimmerman is going to get off. I've read most of the court details and watched some clips.
I've tried to put myself in his position. For one, I wouldn't have been carrying a gun because I don't have one but I can say that I would follow someone until the police arrived in this situation. I've chased kids down my alley when we've had our cars eggs and after having my home broken into I can say that I would have not thought twice about following the person. IMO if you're the kid and you did nothing wrong then you either turn around and ask what's going on or you haul ass because typically kids that have done nothing wrong will run because they're scared. I'm not saying what happened after that is ok but the Florida law protects Zimmerman in this situation.
