I see the value of such a book for city dwellers, as that’s what it’s apparently written for.
Forgive my skepticism, but it’s my belief the bigger the city, the less apt residents are likely to believe in a melt down and the more likely they’d be to either laugh at or worse yet, turn in anyone trying to organize preppers. I also believe that the organizers would be identifying themselves to those that want to loot their stashes when the meltdown happens.
There may not be laws restricting individual preppers, but do such laws exist that could be interpreted as making those that organize preppers as criminals?
There are plenty of laws out there, and if there are not enough, the authorities can always make more.
I do not see this book as only for city dwellers. If order is lost over a large area, (which has happened historically with some regularity, but which seems unlikely in today’s America), then single rural households will not be a viable place to survive, just as single homesteads were not viable on the frontier. A singe family is simply too vulnerable to a small group of raiders.
This book gives some pretty good hints on how to organize a defense within a community.
