Ahh, so you're saying he wasn't looking for trouble? Even after being told to stop following by a 911 dispatcher? And how do you know what happened that night? There are witnesses with different accounts not only that but the lead investigator didn't buy his story so what evidence do you have that we don't know about?
All the witnesses are consistent with Zimmerman. Try again. Zimmerman had all the cuts and bruises consistent with the attack that was reported. The 911 Dispatcher does not have to be obeyed nor should they be obeyed at all times. Google Joe Horn Shotgun to see what I mean.
You can follow anyone and ask anyone anything you want. That is not a crime. Trayvon decided to initiate the physical violence. Zimmerman defended himself. End of Story.
If you hit me in the face, get on top of me, slam my head in the curb and I have a gun, your damn right I`d shoot you.
