A 911 dispatcher is not law enforcement.
EXACTLY!
And they didn't say "don't follow" they said "we don't need you to do that"
It's a perfect example of many folks ignoring the facts and making the story up in their head regardless of the facts and evidence. If they keep repeating it along with the media they believe it to be true.
Police have stated that Martin was the aggressor and that physical evidence shows that along with affirming Zimmerman's account (again, without an attorney present). They have access to all the evidence, we don't.
If there was some shred of evidence that Zimmerman was indeed the aggressor then police would have probable cause to arrest him. They have not and have said countless times they don't have evidence or probable cause. If this made up story in folks minds happened, they would arrest.
But it didn't and there is no evidence of this made up story. I highly doubt a grand jury will give an indictment, no evidence a crime was committed by zimmerman and plenty of evidence of forcible felony by Martin.
