Actually the 911 operator did NOT tell Zimmerman to stop following. What the operator SAID was that following was not necessary. Please, if you are going to retell the story, get your facts straight.
I understand that but the key is when he was advised/told not to follow, he did not ignore the advise. He just said OK. All the race baiters and gun grabbers are saying he ignored the 911 operator. The fact is that he did not.
