Your statement to red that, "You stated that he should have listened to police when he was told "We don't need you to do that" referring to him following Martin" is incorrect. "We don't need you to do that" is what the dispatcher said.
What red said was, "If Zimmerman had listened to the police, who told him to stay away, none of this would have happened."
The misrepresentation/misquoting of this part of the conversation has truly been breathtaking. I've seen more news reports positioning it the way red did and it's just stunning.
There are more than enough reasons to be upset with what GZ did and the feeling that he did not get what was coming to him without making up or changing the facts of the case.
