I am still fond of the Bill Jordan quote "you don't need a gun very often. When you do, you need one real bad."
I'm an LEO, and I have a pistol on my bedstand every night. I live in an OK neighborhood but there's a tavern on the corner and drunks occasionally act up. We have had drug dealers in the apartments next door.... Things can happen.
As well, the wife is here alone much of the time, and she's partially disabled.
No doubt the two dogs are a good deterrent, but they are after all retrievers with nary a protective instinct.
(My ignorant hoosier (no offense to natives of Indiana, here it means "white trash") neighbors think the chocolate lab is a pit bull....)
I'm 65, have been in police work for 40+ of those years and I've never drawn my gun in anger. Could happen tomorrow.
