Take a moment and think, what kind of "mob" might
possibly attack your place???
Seems rather unlikely it will be an organized infantry platoon. Might it be a horde of starving people who think you have the only food and you are the one thing between them living or dying? Are you going to be the Omega Man, facing mutant vampires or some such?? Again, I think unlikely.
More likely is you just happening to be in the way of an angry mob of people protesting some injustice, but containing people who are happy to smash, break, burn, and steal since they can get away with it at that moment.
Friend of mine is fond of the saying "Looting is great fun, UNTIL someone starts shooting at you!"
During the LA riots, when the police had been ordered to leave, the mobs avoided those "Korean shopkeeps" who guarded their stores with visibly armed men.
Fairly recently there was a lot of flap in the news about the couple who had the nerve to (possibly) point guns at the "mostly peaceful" mob (oh the horror!!
) and the mob decided to go elsewhere...
If you're facing a Chicom/soviet style human wave attack, you're not well armed unless you have automatic weapons and grenades and a lot of buddies with the same, AND artillery support. IF you're facing a mob of protesters (about any cause) there a number of examples of those people rapidly finding somewhere else to be when they meet a gun and a person who seems willing to use it.
am reminded of a scene from a bad comedy, good guy facing a gang of bad guys, head bad guys says "what you gonna do? Think you can shoot ALL of us???"
Good guy says "No, but I can shoot YOU!"
Bad guys pauses and says "yeah, I always forget that part..."
If a mob has the discipline under fire to keep coming, they aren't a mob, they're a
unit, and that's a different beast.
