This is not much different from people who have been trying to paint Zimmerman as some kind of crazed vigilante or macho superman who has forced Martin into a deadly confrontation while depicting Martin as a poor, unlucky kid who was forced into a fight, who couldn't even turn his back, had no choice responding as he did, etc. The transcript from the conversation with the dispatcher shows that Martin did get away from Zimmerman and that Zimmerman has lost sight of him, and it is unknown what exactly made Martin re-approach and end up within such close proximity of Zimmerman that he could get into a physical fight with him:
Dispatcher: Are you following him?
Zimmerman: Yeah.
Dispatcher: OK, we don’t need you to do that.
Zimmerman: OK.
...later ...
Dispatcher: OK, do you live in the area?
Zimmerman: Yeah, yeah…..(unintelligible)
Dispatcher: What, what’s your apartment number?
Zimmerman: It's a home. It's 1950 -- Oh, crap. I don't want to give it all out. I don't know where this kid is.
Dispatcher: OK, do you want to just meet with them right near the mailboxes then?
Zimmerman: Yeah, that’s fine.
Some time later Martin ends up at a very close proximity of Zimmerman and enters into a physical confrontation. What exactly inspired Martin to turn around and re-approach Zimmerman will forever remain unknown, but as much as people have been trying to depict Zimmerman forcing this whole incident, I'm just not seeing it: how could Zimmerman force a fight on someone of whom he has lost sight?
Martin did get away from Zimmerman such that Zimmerman told the dispatcher that he has no idea "where the kid is", so Martin couldn't have been fighting merely to incapacitate Zimmerman and make him break off his pursuit. Martin has gotten away and he had a choice to stay away and continue on his trip to his father's girlfriend's place, but instead he chose to re-approach Zimmerman and enter into a fight with him, which then led to his own death. What motivated Martin to do so is unclear, but all of this is not consistent with the picture that some people have been trying to present, that Zimmerman has forced this whole encounter and Martin was merely reacting in self-defense.
