Even if he really was not up to no good, it doesnt matter IF he indeed attacked Zimmerman.
Nemisis, I hate to break it to you but physically most seventeen year olds are not "kids" by any stretch of the imagination and Martin was an example of that. Again in physical terms here. Also some one can kill you just as dead with their bare hands as they can with a weapon so the fact that Martin was unarmed is irrelevant if he was beating Zimmermans head into the sidewalk as is being claimed. Unfortunately Im all too familiar with the fact an unarmed person can kill some one with their bare hands.

Ironically perhaps is that the person Im talking about was the murderer and is my brother in law. Despite the fact he really is a decent guy now, if his victim had a gun and killed my BIL I think the victim would have been in right to do so. Also my brother in law was seventeen when this happened and just got out of prison a few years ago after ten years.
