I think we all know what "friend" made those comments. I will believe it when I see it.
Listen, this "enhanced" photo does not mean it is clearer or more accurate. On the contrary, they simply adjusted the white dark balance and intensified color. It no more shows reality than a retouched, colorized photo does. For that reason, the officer in the photo has a dark line outlining his head, Zimmerman has a dark line outlining his head and body and the red on the sleeves of Zimmerman's jacket is bleeding into the air around him, none of which exists in reality.
This photo is nonsense. It does not show evidence of an injury and it is bothersome that people keep trying to pass a doctored photo off proof of anything. That's not how evidence works.
I am open to the possibility that Zimmerman had injuries. I doubt Taafe's story but if there are injuries, I am certain LE took photos. Further, if there are significant injuries and none on Trayvon, I agree with those who state Zimmerman will have a good chance of walking, whether or not he was the aggressor, (which I think he was, injuries or not).
