Personally, I think the false flag attacks are starting so the media can start painting (even more) the "right wing militia nutjobs" as violent "domestic terrorists".
Although, I don't necessarily think this is the case, yet. The media WILL spin this one against the "right wingers" for sure.
But hell, they've been shooting "revenooers" out in those parts for more than a hundred years. It's not gonna stop now that Obongo is president.
The difference is, now it's going to be blamed on US.
