“I don’t believe that Zimmerman hunted this kid down and murdered him, and it is certainly possible that the kid attacked him. But when he called the police, Zimmerman was told to back off and let them do it. He was obviously not under any threat at that time and the police were on their way.”
Mr. Zimmerman was not commanded by 911 to break off following him. It was just a suggestion. Shortly thereafter Trayvon ran off and Mr. Zimmerman headed back to his truck.
A cursory review of Zimmerman’s 911 calls since 2004 indicates he reported many more white/hispanic male subjects to the police, than black.
Might be relevant to his state of mind.
