Look, this is all just really really really bad logic.
I'm very familiar with the effects the presence of a drawn gun has on people.
This is all horrible and unrealistic.
I would wager all the money I had that if I could go back in time and put myself in GZ's shoes that night, I walk around the corner with my gun at a low ready and TM covers that 100 yds faster than Michael Johnson in the 96 Olympics.
As its already been asked, why can't you just admit the most logical answer is he was scared at first, as GZ got closer TM saw what a dopey loser he was and decided to confront him, things got physical then he realized at some point after the altercation had begun he had a gun?
That's actually logical.
TM justifiably attacking a MWAG he was afraid of, while very likely legal for him to do, is just so ****ing unrealistic.
And of course I would be scared for my life if someone brandished a gun at me. But if you are saying that Zimmerman brandished a gun at Martin and Martin was so scared of the gun he engaged Zimmerman in a fistfight, then you are a crazy person. There is no way that happened.
