There was no reason of intent with the kid for him to shoot? The kid was running away from Zimmerman, not the other way around; and as for why he was wearing the hoody? It was raining.
If ever anyone is in this situation where someone is chasing you to attack you, dont run away from plain site, run towards someones porch or house... Also he had no reason to take his gun. Zimmerman had a bias against black people before he chased him, if you listen to the video he said, these guys are going to get away again" something along the lines like that, meaning he already had an opinon about the kid before he met him? That should have been enough for him to go to jail because its premeditated.
He's going to jail. I can feel it, its only a matter of time before the people start protesting...
Also, Zimmerman looked like a young man himself, Why was he chosen as neighbourhood watcher? They should put strict laws against that, maybe even not have neighbourhood watchers and leave the gun slinging to the police... And it took the police a long time to get there. If I were the parents I would sue the state and the police force for Negligence.
