I'm not one to fantasize about civil war, or armed rebellion, or whatever. I've seen them in real life, in more than one African nation, and they're the very last thing I want to see in these United States! I think most people who've experienced them will say the same. Nevertheless, some worry that we may see some sort of major civil unrest in our cities. With Antifa, Black Lives Matter, urban gangs, and other elements in the news, that's certainly not impossible. If it looks likely, my preferred response will be to get the hell out of the way before things happen . . . but that may not be feasible.
In that case, in a series of articles, Clay Martin offers his thoughts on defensive measures for city dwellers: preparing one's property, choice of defensive weapons, and other issues. I don't agree with everything he proposes, but on the whole his ideas appear sound. His experience was in Iraq, whereas mine was in Africa, but urban conflict isn't all that different anywhere around the globe. His articles are, in chronological order:
Other Things That Go Bang
The Amount of Ammo You’ll Actually Need
Hardening the Home
Surviving In A Concrete Jungle
Escape From NY
Follow each link to read the articles. I hope you won't need the information they provide, but you never know . . .
My favorite quote from Mr. Martin's series:
The one thing I see over and over again in prepping circles is a belief that a mountain of ammo is all you need. Absolutely not true! In fact, I believe that most people would be better off with 300 rounds and the skills of having shot 20,000 as opposed to 20,000 stockpiled and the skills of having shot 300.
Very true, IMHO!
EDITED TO ADD: I've since put up a brief analysis of the urban conflict experienced in Marawi, in the Philippines, two years ago. It discusses that conflict and experience in others, with an emphasis on what it's like to fight your way into, around, or out of a city. It includes a link to a very graphic, brutal video that shows actual murders, combat in the ruins, etc. This is not what we expect to face in US cities; but, given that some law enforcement agencies are already refusing to back up local cops in cities where liberal administrations are giving the mob free rein . . . it's not inconceivable. Go read it, and factor that into your preparations.
