Looks like someone who got into a fight. I have seen people beat up a lot worse in bar fights...of course no one ever shot the other guy for losing a fistfight where I lived, or any places I went too around the country.
This wasn't a bar fight. Zimmerman says that he was attacked by Martin. I could be wrong, but I have seen no evidence to refute that. In fact, the evidence says otherwise.
I don't think Stand Your Ground laws are meant to cover getting your ass beat after you initiated violence. If so, Florida will officially be the wild, wild West.
Actually, it would be a self defense and not stand your ground that would cover it. Are ASSUMING that Zimmerman initiated physical contact ? Because if you know that as a fact, please provide the evidence. Otherwise please stop with your hypothetical analysis of the events that took place.
