OK new info. It appears I may have been mistaken at timing the beginning of George's NEN call at 19:11:12. According to
http://www.wagist.com/2012/dan-linehan/the-missing-230-and-deedees-testimony. (yeah I know, I know. but bear with the sauce for a minute) it was actually 19:09:34.
Now that doesn't change either your or my reconstruction timing of what happened during Martin's journey from 1440 RVC to the walkway tee, just places it 1'40" earlier.
This allows George time after the NEN call to return to his truck, Martin to retrurn and "circle the truck"
7:14:30 Zimmerman gets back to his SUV and is waiting for the police to arrive. Suddenly, there’s a knock at the window, it’s Trayvon.
“Why are you following me?”
“I’m not.”
Trayvon starts to walk away, then runs, between buildings
Zimmerman decides he wants to keep Martin in sight.
Martin leaps out of bushes, fight, "BANG" as before
Now the Zimmermistas at wagist seen to think this justifies George's SYG, but to my mind he is now Guilty Guilty.
OK he may not have lied about the circling, but he got out of his truck to follow Martin TWICE, denied following him, refused to identify himself as Captain of the Watch, despite two opportunities “Why are you following me?” "What's your problem?"
In contrast Martin attempted to disengage, twice, only to find George subsequently following him. Martin's SYG, fully justified.
(If that account is a true one)
