Arrghh - stop asking George questions in this thread
I don't mind George not going directly to his truck except when people believe that Martin 'had to be the aggressor' because him and George ended up meeting each other. Neither has any obligation to do anything or go anywhere.
I will say, that for the entire incident, Martin has only been going in the direction of his home - he's moving in the one direction he would need to go in. George says he 'circled' his truck, but it's unclear if the timeline George gives allows for this.
George, on the other hand, followed Martin first in his car then on foot for over a quarter of a mile. The jury will make of that what they will.
There is no doubt in my mind that if Martin had gone home, or if George had gone back to the truck, the whole thing never happens. If George just stays in his truck, the whole thing never happens. Unfortunately (or not, depending on your point of view), the law does not place any greater responsibility on someone just because they happen to be carrying a gun.
Re: Witness #6 told the combatants he was a calling 911, when a bystander asked George right after the shooting if he should call 911, George's response was, 'no I already called them'. Not, 'someone already called them'.
