Soooo.... *speculative hat on* maybe Zimmerman confronted Martin and tried to grab him, the kid pushed him off and ran, then Zimmerman shot him in the back?
No, Trayvon was shot in the chest (if you can trust anything at this point). But that doesn't mean that Trayvon was on top of Zimmerman bashing his head on the ground. When I read the new witness's statement, taken with everything else I know, I got a mental picture. Especially when I take that statement with what two other witnesses said they said, which was Zimmerman on top of Trayvon with his hands on his back. That was after the shooting, of course. I am wondering, among other things, if Trayvon really died in the position he was found. I am also wondering if cop-wannabe Zimmerman was searching for a gun or ID on Trayvon.
If a person shoots a person who is straddling him at close range, that person certainly bled on and possibly fell on the shooter. I wonder in what position the victim's hands would have to be in to be under his body, as Trayvon's reportedly were. I wonder about the blood that would get on the shooter, and if the shooter's jacket was open or closed. If closed, the gun was probably in a pocket or holster, and would be difficult to get with a person straddling you. If the jacket was open, where's the blood?
I just hope there is a true effort to salvage a decent investigation from the apparently abbreviated one that was done. We'll never know if Zimmerman was high or drunk, but I hope there's enough evidence to show what actually happened, or to give a reasonable idea.
