What does it matter whether it was an instruction or suggestion if he wasn't required to follow it?
Christo doesn't get it. As a matter a fact, this has been my point all along. Legally, as best I understand, he wasn't required to follow it. But that is irrelevant. What's important is this: if Zimmerman chose not to follow it, he comes off like a vigilante dooshbag and that's how the jury will see him, and they may not believe his tale of self-defense. And that's why it's important. Now, is it as important as the broken nose or other injuries? Hardly. Those are much more important IMO. But this is important nonetheless.
All of these issues go toward Zimmerman's credibility on the stand. And that's really what this trial will be all about IMO. It certainly won't be about whether or not what the 911 operator said was an instruction or a suggestion. If it becomes about that, Zimmerman's already lost, because the jury will never buy it. I think the defense is smart enough to realize this, and they'll never argue the point. What they'll do instead is argue that Zimmerman DID follow the instruction/suggestion. At which point, again, it becomes a matter of who the jury believes. The broken nose evidence will help the jury believe Zimmerman. The comment Zimmerman made about "punks always getting away" will help the jury disbelieve Zimmerman. If the prosecution can establish that Zimmerman did in fact not do what the 911 "suggested", that will also hurt Zimmerman. But in the end it will come down to Zimmerman's believability on the stand.
