This doesn’t need to be re-litigated, especially by someone who rejects facts that disagree with their wishes. The jury heard all the evidence, had the tapes of the phone conversation Zimmerman had with the police. The police told Zimmerman to stop following and return. He complied. At that moment, Martin was still walking in front of Zimmerman and away from him, so they were then walking away from each other.
Moments later Martin had knocked Zimmerman down and was pounding his head into the cement. Injuries to the back of Zimmerman’s head prove that.
So it was Martin who reversed course and caught up with Zimmerman, not the other way around. I know how desperately you don’t want that to be true, but the evidence proves it and the jury used the evidence in their verdict.
