I just read a link to this on Slashdot. I am quite concerned about what it says.

In a stealth maneuver, President Bush has signed into law a provision which, according to Senator Patrick Leahy (D-Vermont), will actually encourage the President to declare federal martial law (1). It does so by revising the Insurrection Act, a set of laws that limits the President’s ability to deploy troops within the United States. The Insurrection Act (10 U.S.C.331 -335) has historically, along with the Posse Comitatus Act (18 U.S.C.1385), helped to enforce strict prohibitions on military involvement in domestic law enforcement. With one cloaked swipe of his pen, Bush is seeking to undo those prohibitions.
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.”
President Bush seized this unprecedented power on the very same day that he signed the equally odious Military Commissions Act of 2006. In a sense, the two laws complement one another. One allows for torture and detention abroad, while the other seeks to enforce acquiescence at home, preparing to order the military onto the streets of America. Remember, the term for putting an area under military law enforcement control is precise; the term is “martial law.”
Section 1076 of the massive Authorization Act, which grants the Pentagon another $500-plus-billion for its ill-advised adventures, is entitled, “Use of the Armed Forces in Major Public Emergencies.” Section 333, “Major public emergencies; interference with State and Federal law” states that “the President may employ the armed forces, including the National Guard in Federal service, to restore public order and enforce the laws of the United States when, as a result of a natural disaster, epidemic, or other serious public health emergency, terrorist attack or incident, or other condition in any State or possession of the United States, the President determines that domestic violence has occurred to such an extent that the constituted authorities of the State or possession are incapable of (“refuse” or “fail” in) maintaining public order, “in order to suppress, in any State, any insurrection, domestic violence, unlawful combination, or conspiracy.”
For the current President, “enforcement of the laws to restore public order” means to commandeer guardsmen from any state, over the objections of local governmental, military and local police entities; ship them off to another state; conscript them in a law enforcement mode; and set them loose against “disorderly” citizenry – protesters, possibly, or those who object to forced vaccinations and quarantines in the event of a bio-terror event.
The law also facilitates militarized police round-ups and detention of protesters, so called “illegal aliens,” “potential terrorists” and other “undesirables” for detention in facilities already contracted for and under construction by Halliburton. That’s right. Under the cover of a trumped-up “immigration emergency” and the frenzied militarization of the southern border, detention camps are being constructed right under our noses, camps designed for anyone who resists the foreign and domestic agenda of the Bush administration.
