Once, a coworker of mine was jumped by another guy near our office as he was walking down the street. Apparently, he got the best of the guy who jumped him, and as the police pulled up, the guy who jumped him began yelling for help. And the police started to arrest this coworker.
Luckily, the whole incident occurred in front of a restaurant filled with witnesses who ran outside to let the police know who the real aggressor was.
IOW, just because someone is yelling for help, that doesn’t mean he wasn’t the aggressor. IMHO, Zimmerman, in his own mind, probably thought he was defending his neighborhood and himself. He probably couldn’t see how his actions indicated otherwise.
There's no denying this situation is a tragedy and that wouldn't change even if Trayvon had a gun or knife. Trayvon had his whole life ahead of him and this shouldn't have happened; regardless of who is at fault here. The point I am trying to make is with Sharpton's insertion in the matter and the media feeding frenzy that has ensued, nothing should be taken at face value here.
