Martin has every right to be afraid. Every child's worst nightmare, being followed by a stranger, etc. Yeah, sure, "he's starting at me, he's got his hands in his waistband, sh!t, now he's running." Full of fear, sure.
If Martin had been mounted on Zimmerman, as Zimmerman claims, Zimmerman could not have gotten the gun. Try it in the jury room. (that'll backfire, Martin's legs aren't necessarily tight against the sides of Zimmerman's body). Guys says he isn't going to show the jury on the mannequin (doll).
Why would Zimmerman go through, past the T, if he lost sight of Martin. There is no reason. (well, use some conjecture, connect those dots, maybe Zimmerman is looking down a street that has some street lights for a glimpse of a fleeing Martin).
If was yelling help, why wasn't he hoarse afterwards?
This isn't self defense, this is self denial.
