At least not supported:
Zimmerman says Martin was on top of him, slamming his head against the ground when he grabbed his gun from a holster before Martin could get it.
There were no skin cells from Trayvon Martin on the pistol used to kill him. Nor were there any found on the holster.
Yet Zimmerman concocted a narrative with or without the help of the Sanford police department that had young Trayvon as an aggressive attacker bent on harming poor, scared, defenseless stalking Zimmerman. Yet there has yet to be any proof that Trayvon was doing anything more than trying to return home from the store unmolested.
On the other hand repeatedly Zimmerman has lied, hidden, or obscured evidence of his continuing wrongdoing.
This report pretty much clinches for me the presumption of guilt or innocence of Zimmerman when compared to what has been revealed about his morals thus far.
