Work...you mean like down at the gun factory, er, nope. Maybe at the big box sporting goods store, er, nope. Like over at the police station, er, nope. Say..the military base, er, not really. Well, wait a minute, you know they always have mass shootings down at the gun shop, er, nope. Well by golly there is always somebody whackin' somebody over at the gun club...er, nope.
The death of common sense.
I would like to work this backwards, I'm sure there are studies that show, people under 6' tall get targeted more than people 6' or taller. Does the perp look for small people or AVOID, big people?
A Gun free zone might not be the attraction, probably not, but the Gun saturated zone is a definite deterrent. Ergo, no moves on police stations, shooting ranges, martial arts academies, Psycho people are crazy, not stupid. I do agree that the mass stuff happens mostly, in places the perp is comfortable in, but as most of you know, a man drove his pickup into a Luby's cafeteria, in Killeen, Texas, through a window and systematically killed multiple patrons. He did not work for them, maybe He ate there once, who knows, and then killed himself.
Google, Dr. Susan Gratia, she was there!!!
Now it is hard to do a study on brandishing a firearm and the perp leaves, no shots fired. This has happened twice to me, when I was young, did I call the police, no, it was quick down and dirty, nowadays, I don't show my hole cards until they are needed, and then shots will probably be fired. But I avoid this situation, I walk softly.
