The fact that Zimmerman was getting his ass kicked is only evidence that he was losing, not that he was attacked. I've seen plenty of fights where the guy who started it ended up losing.
Maybe martin did attack zimmerman - but maybe he didn't - it is equally plausuble that martin was fighting to keep the stranger who followed him from pulling the gun or the trigger.
You don't know.
Nobody here knows.
As for your statement that zimmerman was key in getting charges against the cop's son --- please provide a link. I know about the incident but never heard about zimmerman being involved.
You are correct that there were no witnesses to the start of the fight. The investigator, Dale Gilbreath, admitted that at Zimmerman's bail hearing. The problem the prosecution has is that THEY have to PROVE Zimmerman guilty. Zimmerman does not have to prove himself innocent.
My own speculation is that both were spooked by the other, and 17 year olds think they can never die. When the two of them got to be face to face (probably by Trayvon accosting Zimmerman) and started a testosterone fueled pissing match, Trayvon thought that Zimmerman was pulling a weapon when Zimmerman went for his phone. Trayvon then sucker punched Zimmerman and Zimmerman shot Trayvon in self-defense. A tragic case all around.

Here's a link. You can find more by googling Zimmerman Sherman Ware (the homeless guy's name).
