Interesting. I am watching WFTV right now. Check this out:

(excerpt)
Zimmerman told police Martin punched him in the nose and bashed his head on the sidewalk, but in the surveillance video it does not appear that there is any blood on him.
However, it is possible Zimmerman was treated at the scene before police drove him into the garage. Police have said he was bleeding when they arrived.
But in the video, it does not look like there are any cuts or blood on the 28-year-old’s head and nose, yet Zimmerman said Martin punched him in the nose and bashed his head on the ground.
The injuries were not bad enough to go to the hospital that night. However, sources tell WFTV Zimmerman did go to the hospital later and provided pictures of his injuries. WFTV has requested those images from the Sanford Police Department, but has not heard back.
