A little overblown here. It doesn't take the anarchist cookbook to start a riot, just a little state sponsored oppression and people with little to lose (which is, I believe, part of the gp's point)
This, and so much this. Generally, places lacking reason to riot are riot-free.
More broadly speaking, I'm not sure how this is any different than folks having firearms in their homes for self-defense. It is just one version is more socially acceptable than the other.
