Perhaps, Zimmerman shot him while Martin was on top of him, pushes him off and rolls away. Anything can happen.
That’s exactly my point. These two bimbos are lying. They didn’t see anything except Zimmerman walking around afterwards. Perhaps he might have gotten down on his knees to check the kid’s pulse. But the idea of him being on top of the kid, sitting on his back and shooting him in the chest is ludicrous. Hopefully, the cops should be able to tell by the angle of the bullet who was where.
