Ribs,
if that scumbag came into a place I was eating at, he would have had six hollow core rounds in his sorry body, bleeding like a stuffed pig, and be deader than a doorknob.
I do not waste time when someone threatens to shoot.
He who shoots first while aiming, shoots last....
And my S&W Compact 9C is loaded and on me ready to use if need be.
CONGRATS to the GUY who killed that miserable piece of trash.... Hope the dogs or pigs eat his corpse...
