I’ll have to disagree. They are about 5-6’apart when the shot was fired.
Disagree with what? That the shooter's life was not in immediate danger when he pulled the trigger? If you've watched the video I linked to in post 19, please explain your view of the matter.
McGlockton (ironic name) was backing away after the firearm was presented, but Drejka fired anyway. Drejka may have been disoriented from the shove, but he did have enough presence of mind to draw.
Given that Drejka started the argument with McGlockton's partner, and McGlockton only saw her and Drejka standing less than a foot apart yelling at each other, it wasn't unreasonable for McGlockton to react the way he did. He separated his partner and the person confronting her, then maintained his distance from Drejka.
Drejka was the aggressor from the beginning by trying to be the parking lot police, a role he apparently has performed many times at that same convenience store.
