"I'm merely attempting to get at the gray areas presented to armed citizens anytime they confront these situations."
As far as I am concerned personally, it's not a gray area.
I don't chase.
This one is, I think, quite a bit different from some of the other's that have cropped up.
This one can be (IF the stories are accurate) seen as almost two different crimes.
Crime one was the mugging.
The AC chased the guy (any indiciation if he chased him with his carry gun out?), after which the second crime cropped up when the mugger pulled a gun.
I could see the AC being in trouble IF he chased the mugger with his gun out.
If, however, he was simply chasing to recover property and drew after the mugger drew his gun, I would think it would be a clean shooting.
