Zimmerman’s brother said that Zimmerman said they were struggling for the gun. And, you avoided the question...did you ever see anybody start a fight and then get his ass kicked? It’s simple...either yes or no will suffice.
Zimmerman himself also told police that Martin saw his gun and went for the weapon. At which time they struggled and he shot Martin.
And yes, I have seen someone start a fight and then lose. I am currently involved in such a thing on a blog, where this guy, completely devoid of reality, started speculating things which do not match the evidence. He is losing the fight, but doesn’t even realize it - it is almost sad.
