Guess you didn't catch in the 911 transcripts that YOU copied and pasted but Martin was running FROM Zimmerman, not TOWARD him.He was told to call the non emergency dispatch for reasons as stated. He did that!
They just did NOT get there in time, before Zimmerman was ATTACKED by Martin!
And you didn't answer the question about Zimmerman knowing about Martins Facebook postings so I'll take that as a NO he didn't know so that would make no difference to him, no reason to fear him.... He was scared because he was black..... Racist.
That is all, Zimmerman goes to prison.
