I agree BB, BUT being followed does not give a person the right to attack another person. He still had the right to defend himself. In my opinion if martin had never attacked him, this would have never happened.
I'm under the impression that Zimmerman went right up to Martin. And then a verbal altercation got started that turned physical. Am I mistaken? If Zimmerman stayed back and was just following Martin but had not engaged him in any way, and Martin saw him and came back to whip Zimmerman's butt, well ... then ... THAT'S a whole nuther ballgame ...
