Combined with a few more pesky details:
1. Witness reports have TM on top, beating Zimmerman.
2. Zimmerman has head wounds and broken nose, TM's only injury (per the mortician) is the gunshot wound which abruptly ended the beating he was administering to Zimmerman.
There's no logical reason the guy on top is the one screaming for help. TM's own father originally said it wasn't him, and then changed his story later on. On the other hand, the "experts" who claim differently are getting paid to contradict the obvious.
