About the rise of right-wing militias and breakup of the USA
Militia Report 2009 from Missouri
This report is really well done, in my opinion. It looks into the reasons why militias emerge in addition to describing them factually, giving a compassionate yet realistic look into their psychology.
Even more interesting, it describes their fears — RFID, marked ammunition, the NWO — and points toward others theorizing the USA will break up because of a permanent values schism between the liberal Left and the traditional Right.
