I've avoided this thread for long enough, but I guess I'll add in my 2¢ about the Zimmerman case..
Honestly, I was upset to see that Zimmerman got away with what he did. It may be true that he didn't murder Martin, but what I dislike him about is that he clearly did not follow Sanford Police's orders when they told him not to follow after Martin. That, my friends, is being a vigilante. However, I do believe that Zimmerman is at fault and he should have been proven guilty of murder (or manslaughter), because he used lethal force against Martin, which is a stronger force than fists. Not only was this case a trial against a crime Zimmerman was convicted of, it was a challenge to Florida's 'stand your ground' self-defense law.
