Um, that helps Zimmerman, but it doesn't turn this into "duke rape case" 2. We already knew he had some injuries on the back of his head from the fight. But it doesn't tell us who started the fight. It also suggests that Zimmerman knew that he was going to be in legal hot water, since he had an acquaintance of his take this photo. It's fascinating that these seeming wounds would not require bandages.
Also today, we had this come to light, that doesn't help his case:
While interviewing Zimmerman’s current wife, the state proscecutor read from an affidavit by the ex-girlfriend. She alleged in the sworn statement that he “pushed her,” then slapped her with an open hand to the mouth and “asked her how it felt.” She said he “picked me up and threw me on the bed” and then “grabbed me again.” Zimmerman’s wife responded that her husband was simply trying to “protect himself from being attacked by her.”
