This was your claim I was responding to:
When in fact the dispatcher clearly told Z that "we do not need you to [follow M]". Sure sounds like a request to me.
Whoever wrote the affidavit for arrest agrees:
Z was given a very serious sounding suggestion to stop following M by a police dispatcher. This suggestion was given during Z's pursuit of M and was within several minutes of the fatal shot being fired. Z responded to this suggestion with the word "Okay".
He was told not to follow AFTER he was already following. The *possible* misinterpreted request was BEFORE he started following. He responded to the statement, "we don't need you to do that," with an okay. 15 seconds later, he is no longer walking. Listen to the recording. At exactly 2:43 seconds, you no longer hear wind. He does not sound like he is following anymore. It sounds like he is standing somewhere, distracted, hitting something. "In my minds eye"
The case the prosecution is going to put out, of course, is going to say Zimmerman continued to follow, otherwise, they don't have a case. The prosecution (whether they have evidence that we do not know or are purely sympathetic to the family, or are politically motivated) are using Trayvon's girlfriend's account because that is what the case is resting on. This is why there is a trial, though, the prosecutor will have one version and, you should be sitting down for this; the defense is going to have a different account.
