There are two areas of the human body where a single shot even from a 22lr can bring the perp down immediately: the brain pan and the bladder and surrounding nerve-heavy area. One is a lot more painful than the other, but I’d rather a perp be writhing in agony screaming on the ground than still coming for me after the first shot to the center body mass..
“Groin shot. On purpose?”
It’s called “gun control.”
