Leaving the above aside, let's say Martin was on top. You state that he was in control of the situation! Was he? How much in control can someone who is unarmed be against someone who is armed? In your scenereo I'd have to argue there is a case of self-defense that can be made for Martin as he was unarmed, and fighting an armed man. I don't know about you, but if I found myself in that position I wouldn't stop hitting the other person until I knew he waw either no longer armed or completely incapacitated.
How would Martin know Zimmerman was armed until Zimmerman produced the handgun and fired it?
That report came from one of the 911 calls. I noticed that too. Zimmerman himself described it as "a dark hoodie, like a grey hoodie." Maybe Martin had a white t-shirt underneath the hoodie and it was zipped down a bit and that's what the 911 caller saw. Or maybe it's just human error. Eyewitness accounts can be very unreliable for details sometimes, especially when you're observing from a distance. I would go with Zimmermans account since he was probably paying the most attention. But beside that, the one witness who identified himself only as John and was closer to the scene, pretty much identified Zimmerman as the one being on the ground. Besides, we have physical evidence that supports Zimmerman's account.

What evidence is there that demonstrates Martin knew Zimmerman was armed, and further, that he brandished it? None that I know of...
