We don;t know yet, but perhaps the shop owner could not have a gun. I wonder how many people are unpleasantly surprised when they're denied clearance for a firearm because of some piddly-fartin' violation or another. And the lawmakers keep felonizing previous non-felonies.
I still think that jump over the counter was absolutely equal to a home invasion, no lame legal excuses allowed.
Revenge? I kinda wondered about that myself.
That class of people have different moral structures than you and I, I'm thinking of the line in the movie Scarface(?) where Al Pacino says, in a heavily accented aggressive manner, "You *expletive deleted*ck-a me, I *expletive deleted*ck-a you."
I think that was the movie --memory fades. But to me that one scene always epitomized the escalation of violence in vengeful situations at that level of "morality."
