Witness Says He Saw Trayvon Martin Straddling, Hitting George Zimmerman

Didn't see anyone get their head banged against the sidewalk though

 A witness who had perhaps the best view of the struggle between the neighbourhood watch volunteer charged and the black teenager he is charged with killing testified Friday that it appeared the unarmed teen was striking the defendant while straddling him.

However, Jonathan Good said he did not see anyone's head being slammed into the concrete sidewalk, which George Zimmerman has said Trayon Martin, the victim, did to him. Good initially testified that it appeared "there were strikes being thrown, punches being thrown," but during detailed questioning he said he saw only "downward" arm movements being made.
