A security video that shows neighborhood watch captain George Zimmerman being led in handcuffs from a police car after he fatally shot Trayvon Martin is adding to the debate over whether the shooting was a case of self-defense.

From the video, there doesn't seem to be any visible injuries on Zimmerman's face or head --- a stark contrast to the picture he attempted to paint of a fight between him and Martin. 

Admittedly, the video isn't exactly in high definition. Still, is it enough proof that Zimmerman (and the police) lied about what happened that night?
