You're a student of Arthur Kellerman, aren't you? He's the guy behind the "a gun is the home is 47 times more likely" BS factoid so beloved of the Brady Bunch.
Fantasy, indeed.
I've already cited the Orlando rape problem, and its magical solution, in another thread. Handgun defense only rarely involves shootouts. It seems to work, shootouts or no.
Sorry, never heard of him. My own experience. I live in a place (Alaska) where
in most of the state, hunting is a necessity, not just recreation, so gun ownership is high. Still, many more people own guns for reasons of self image than actually bestir themselves to go out and hunt.(dragging a ton of dead moose through peat bogs and alder thickets is not my idea of fun)
When I was a kid on Kodiak island in the 60's, it was usual for kids to have their own rifle, as young as 9, to carry it constantly, and shoot anything that moved, sea lion, sea otter, deer, rabbit, weasel, beaver, land otter, seagull, raven, eagle, or whatever. There used to be a $3. bounty paid by the state for a sea lion nose, or bald eagle feet, so it was a bit like collecting soft drink bottles. And some things that didn't move, such as signs.
I don't recall anyone I know personally using a gun for self defence.
There are plenty of bears where I live, a guy who lives about 3 miles away shot one a few years ago on his place, supposedly it was after his goat, but more likely he just wanted to shoot something. Bozo's with guns are more of a danger than bears.
