That may not be true. Joe Oliver, Zimmerman's media spokesman, said there is other evidence that will come out that will exonerate Zimmerman, including eyewitness testimony. We do know from the City Manager's statement of events that the physical evidence and witness testimony support Zimmerman's version of self-defense, which is why the police did not arrest Zimmerman. Let the evidence all come out rather that trying to speculate what may or may not be the facts?
Much evidence and facts are already out.
Zimmerman had a broken nose, and bloody injury to the back of his head.
The back of Zimmerman's shirt was wet and had grass or grass stains on it.
The eye and ear witness, John, saw Trayvon beating Zimmerman. (the attack happened right outside his window)
The eye and ear witness, John, heard Zimmerman (no question it was Zimmerman) crying out for help.
The police did not arrest Zimmerman, and returned the gun to Zimmerman.
