A couple of minor items from recent history, such as Klamath and Elko show that there are times at which people are fed up and decide to fight back. In both cases at the time, the government did back down.
I suspect this is reason behind the talk about moving 20,000 soldiers onto American soil to handle 'special events', and Obama's talk about a National Security Force. Those folks know, at some reptilian level, that people are no longer buying into 'the game' of politics over the last couple of decades, and are, at some level 'withdrawing consent'.
Could be right... I think we are going to find out.
