I don't think most of those things are true though. Maybe about guns, but loads of people have always had guns there and spells of increased gun purchasing happen pretty often. Aside from that, I don't think there's much reason to believe the state has lost legitimacy across the majority of the country and there aren't currently any serious challenges to its authority. Not to mention a lot of these militia types seem to be acting in support of the state. I'd also question whether the police are really out of control or actually performing their function as intended. Isn't being 'out of control' part of the normal repertoire of police forces?
