This is a lie that has been perpetrated by the MSM by using edited tapes. The fact is the 9/11 call in which the operator asked him to stop following GZ replied "OK" and broke off the surveillance and told them he was returning to his truck to meet the cops. He was then followed and attacked by TM. Eye witnesses saw it happen. TM was not standing his ground but initiated the confrontation. GZ, BTW, is not pleading stand your ground but simple self defense.

Well, there's one sure way to end the squabble --- provide a link to the witness who states that he saw TH follow and attack Zimmerman and we can all agree...
