Many, including Trayvon Martin's mother, pointed to what seemed to be a lack of injuries on Zimmerman in the video's previous quality as explanation for Zimmerman's guilt. 

He claimed that he shot Trayvon Martin out of self-defense.

NY Daily News says, Zimmerman, 28, says Martin, 17, decked him with a punch in the nose and repeatedly slammed his head into the ground before he shot the teenager Feb. 26.

His lawyer says Zimmerman’s nose was broken and the back of his head had two gashes. A police report said his nose and the back of his head was bleeding.

Zimmerman's lawyer also claimed that the video's previous quality was too grainy for the wounds to be visible.  

Huffington Post said, However, the funeral director who handled the body of the slain teen told Nancy Grace there were no cuts, bruises or signs of a fight on Martin's body.
