Maybe I'm behind the game, but I only discovered this blog recently. The impression I get from this "Charles" dude is that he's just about the single biggest douche on the Internet.
These people are talking out of fear. They have no concept of what is going on in the real world, what is happening on main street America. Posse Comitatus is my neighbor. In fact, this whole region is settled by the Comitatus family. How could that blogger not realize this?
