If the stuff really does hit the fan, hard, how will you protect yourself and your family from the violence?
That's really what it comes down to, doesn't it? If the economy and society collapse, what will constrain the formation of violent groups looking to survive? What will keep them from eventually finding you, wherever you are, whether you're hiding out in the city, an anonymous corner of a suburb, or in your rural retreat?
There's a lot of material, some of it good, written elsewhere on the Internet about how to prepare for hard times that include violence. One of the newest and perhaps the best I've read is The Lizard Farmer. In this episode, I give a quick overview of the problem, as TLF sees it, and some of his recommendations.
You just cannot assume that you will be left alone after the SHTF. And staying alive could turn out to be much more complicated than simply defending yourself or your family against an attacker.
Check out The Lizard Farmer. He's been posting great material since April of this year, with a lot more to come, hopefully.
