I thought George's first priority was to keep from getting his face smashed. Wasn't he just one more blow away from spoon feeding and pampers for the rest of his life? If he puts his guard down to go for the gun there will be a fist comming through. That is, unless Trayvon had already stopped fighting him.
Did any of the witnesses hear Trayvon tell George he was going to die? Did George suddenly become a psychic and knew that was what Trayvon was thinking without it being said? Or could it be that George only thought that to himself while he was busy screaming his head off? Perhaps though, it was in the moment that trayvon started to get off of George that George saw the opportunity to stop this ******* before he gets away.
