Be honest with YOURSELF, Jim. Your son would have come back to you unharmed because he would have gone directly home insterad of loitering around in the rain, then approaching GZ ready to fight. Trayvon would have been unharmed if he'd done the same....gone drectly home.
I would hope the hypothetical young Wallis would end up the same way if he attempted to murder someone for looking at him and talking in his cell phone.
