ABC news has a video taken at the Sanford police station, where they bring in Zimmerman. His face shows no signs of damage whatever. You can see that his head has no bloody scabs, wounds or abrasions on his head, which allegedly Martin beat against a sidewalk. His nose is unbroken.
The funeral director that dressed Trayvon's body said there were no abrasions on his hands.
In the initial report, no one said that they even brought Zimmerman into the station, and yet there he is, at the police station. The police wanted to book him, but the prosecutor did not agree, they say.
