No, there hasn't been a boy who contradicted anything zimmerman said.

There are people who have CLAIMED that happened, but it hasn't.
Ah. So someone who is anonymous is a reliable witniess and a boy who has been identified only "CLAIMS" things. Hmmm. Yeah that's objective
The cops and the prosecutor don't think they have enough to arrest so far. And it's unlikely at this point that they will.
And you can't *murder* somebody legally. Murder is by definition, breaking the law.
Murder is only murder if you're caught and convicted. Guess what. There have been murderers who have broken the law and gotten away with it. Shocking I know!
And there were not *instructions*. The 911 operator told zimmerman THEY DIDN'T NEED HIM to follow. And he agreed, and that's all we know, really.
