Re: "Absolutely no one can make sense of the United States' infatuation with firearms."
We have bears, mountain lions, bobcats, foxes, racoons, rattlesnakes, coyotes, feral dogs & cats, and other fauna that threaten the livestock.
Good luck trying to take on a bear or mountain lion with a hand-gun, because an injured and angry bear is so much safer to deal with. Snakes are best left alone, all those other animals are best handled through the judicious use of chicken wire and cement, like the rest of the world manages to do without shooting at everything that moves.
