Seriously, in what civilized country can an armed bully appear threatening, provoke an altercation, shoot the other guy, and not even get time for manslaughter? The fact that Zimmerman provoked and appeared threatening to Martin with the knowledge that he had a gun and was willing to use it, and that Martin could have reasonably assumed that to be the case, also means that whatever force Martin used was certainly not in excess with regard to the danger posed by Zimmerman. Even if Martin attacked him physically, it's not unreasonable for someone in Martin's situation to presume that Zimmerman might be a trigger-happy, bullying nutso looking for an opportunity to shoot a black guy becaused he made a funny move.
