Actually, Zimmerman's claim of how the fight started is flat-out bizarre. So Zimmerman, after completing his police call, wanders through the cut through, in order to look at a street sign that won't be there, on a street that he already knows the name of. He then begins to walk back to his truck, when a now angry Martin emerges from the south route, and angrily approaches him. Zimmerman, who has already identified him as "up to no good or on drugs", sees his angry approach, and then *drops his guard and likely his gaze*, to reach for his cell phone. Martin then punches him and knocks him down in one blow, and then straddles him and begins bashing his head on the concrete, even though this punch would have put Zimmerman north of the T-junction, where there is no concrete. Martin also tries to smother Zimmerman, who is clearly screaming despite being unable to breathe.
I'm sorry, I don't buy this one for a second, it simply makes no sense. Which is why I keep waiting for his actual statements to come out, instead of the various false and often contradictory leaks we've heard so far.
I knew better than to chase people around by the time I was twelve. Zimmerman apparently knew better as well, given his previous police calls, but chose to do it anyway.
