Didn't BushCo suspend Posse Comitatus a few years ago? I remember there was this big old flap about it at the time...
"Public Law 109-364, or the "John Warner Defense Authorization Act of 2007" (H.R.5122) (2), which was signed by the commander in chief on October 17th, 2006, in a private Oval Office ceremony, allows the President to declare a "public emergency" and station troops anywhere in America and take control of state-based National Guard units without the consent of the governor or local authorities, in order to "suppress public disorder.""
In essence, it repeals Posse Comitatus. Not a stretch to deploy federal troops whenever wherever, although I do wonder who took it upon themselves to give the order...
I think that was repealed in 2008.
