John said Zimmerman was thrown to the ground and had his head slammed on the ground? You sure? Link or you jumping to conclusions?
I'm going by the evidence and John's description of what he saw. Are you really this dense? C'mon man, there was a wound that needed stitches on the back of the guys head, Zimmerman said he was slamming his head into the ground and he started yelling for help. John at least confirms tray on was atop Zimmerman and Zimmerman called for help. Put 2 and 2 together. If this is what happened, I don't know, I was not there. Neither were you. But the cops saw the wound on the back of his head and offered him medical help. He also had a broken nose.
This is all we know about the altercation. We don't know if Trayvon had visible bruises on his face, do we? Do you think by now we would've heard about that? I do, and until we do, all we have is what is reported on the news.
I think this needs to go to court. That's what I gather from the information provided. But if what Zimmerman says happened is what happened, he had the right to shoot him. I don't think he should've shot to kill, but i don't know if he had that option.
We just have to wait and see. And calling someone a name isnt enough to convict him. You seem to think it is.
