As I have said to others, GZ made serious mistakes in judgement, especially in not relating to TM the reason for his interest in him, but none that I see as grounds for TM to strike him. As the anecdote about your daughter's "training" indicates, you must see the distinct possibility that TM may have decided to strike. You don't bring Skittles and an attitude to a gunfight twice.
Allow me to point out a significant lie that I believe he told in his account. He claims that after he saw Martin run behind the row houses, Martin returned all the way back again and circled his car in a menacing manner. I contend that this never happened and is easily proven false. I hate the commentary on this video, but as far as I know it's the only one where someone walks the path that Martin walked and it's matched up with the NEN call.

[ETA: Sorry, the start time isn't working for me, so if you want to skip ahead, start at the 3:30 mark.]
Now here's why I think this will prove this lie. At the time that the guy in this video gets to the clubhouse, you hear "****, he's running", so we know that this is when Zimmerman exits his vehicle for good and the dispatcher asks "are you following him", right?
So if he could only have reached the clubhouse before Zimmerman exits, how is it that he ran behind the row houses, circled back onto the street, and then circled the car, then ran again?
He couldn't, therefore Mr. Zimmerman completely made that part up in an effort to make Martin seem menacing. The prosecution is certainly going to have their own version of this where they walk the path, match up the locations to the NEN call, and show that Martin ran somewhere just past the clubhouse and that as soon as he did, Zimmerman exited his vehicle.
So, ignore this guy's commentary and just listen to the NEN call and match it to the locations up until about the 5 minute mark when he says "he's coming to check me out". "****, he's running" happens at the 5:45 mark. That's as far as you need with the video, since he goes off on some weird theory. But basically, there's no way any of that circling happened.
And remember, what made Martin suspicious was that he was walking slowly, so if anything, this guy is walking too quickly.
