Some evidence could still come out that shows Zimmerman was brandishing his weapon towards Trayvon or giving Trayvon some other legally-valid reason to be resorting to physical violence against Zimmerman. But everything I have seen so far is consistent with a kid, starting to embrace the gangsta culture in his Twitter posts and photos, taking umbrage with getting followed, and then acting out the gangsta street creed by assaulting Zimmerman for disrespecting him.
I don't have any particular emotional need to 'support' Zimmerman over Trayvon. If evidence comes out that pokes holes in Zimmerman's story, then let's see it and put Zimmerman on trial if that is warranted by the evidence. But I sure as heck ain't going to cotton to pinheads using FR to promote the left-wing attack agenda against Zimmerman that is based on lies, emotionalism, manipulation of evidence and intimidation.

I think your scenario is the best fit for the facts up to the point of the use of the gun. I think there was a point where Martin finally saw the gun and at that point both were in fear of getting shot. Martin could have went for the gun to protect his own life but at that point Zimmerman has to assume that Martin's intention is to kill him and thus is in fear of his own life and is justified using it for self defense.
Tragic but not all tragedies are criminal.
