Surveillance Video: No Injuries on Zimmerman
The plot thickens, as George Zimmerman is led into police headquarters handcuffed the night of the killing of Trayvon Martin, with no signs of injury or blood.
Here's Anderson Cooper showing the video with commentary - but you have to watch an ad (which I'd like to see banned from youtube!).
The blood on Zimmerman may have been washed on when he was treated by EMT's. But then ago, maybe not. We'll learn from police and other witnesses eventually.
