Did he have the right to assault him, though, based on any evidence we have?
Where is the evidence that he did assault him?
You claim that you were on the job for twenty years...in all that time how many times did you see the guy who threw the first punch end up getting his ass kicked?
Where is the eyewitness who said that Martin threw first?
Zimmerman's brother said that Martin was trying to get the weapon. If this is true, when did Martin first realize that the guy following him was armed? Did Zimmerman reach for it? Did he already have it out?
You don't know. And that's the point.
What if Zimmerman lost Martin (as the tapes indicate), and turns around to go back to his truck? Does Martin still have the right to confront? Seems like at that point he’d be advancing, and not “standing his ground”.
Another question. Why doesn’t Martin call the police if he feels threatened?
