Rob lives in a vacuum. While I agree, if you are in gunfights then you are most likely already dead, the fact that so many live in urban areas and the 'flight' will be bring encounters where more is better. That said, hunker down during the day, move at night is the smart option
I agree with your sentiment as well. That's why I included the "otherwise clean" . . . But, if you shoot an intruder with a hollow point, shot out of a gun with a 30 round mag and a threaded barrel . . . You're starting off on the wrong foot . . . In fact, you likely don't even want to have those things in your safe.
