The Defense Authorization Act of 2006, passed on Sept. 30, empowers President George W. Bush to impose martial law in the event of a terrorist "incident," if he or other federal officials perceive a shortfall of "public order," or even in response to antiwar protests that get unruly as a result of government provocations. . . .
It only took a few paragraphs in a $500 billion, 591-page bill to raze one of the most important limits on federal power. Congress passed the Insurrection Act in 1807 to severely restrict the president's ability to deploy the military within the United States. The Posse Comitatus Act of 1878 tightened these restrictions, imposing a two-year prison sentence on anyone who used the military within the U.S. without the express permission of Congress. But there is a loophole: Posse Comitatus is waived if the president invokes the Insurrection Act.
Section 1076 of the John Warner National Defense Authorization Act for Fiscal Year 2007 changed the name of the key provision in the statute book from "Insurrection Act" to "Enforcement of the Laws to Restore Public Order Act." The Insurrection Act of 1807 stated that the president could deploy troops within the United States only "to suppress, in a State, any insurrection, domestic violence, unlawful combination, or conspiracy." The new law expands the list to include “natural disaster, epidemic, or other serious public health emergency, terrorist attack or incident, or other condition" -- and such "condition" is not defined or limited. . . .
The story of how Section 1076 became law vivifies how expanding government power is almost always the correct answer in Washington. Some people have claimed the provision was slipped into the bill in the middle of the night. In reality, the administration clearly signaled its intent and almost no one in the media or Congress tried to stop it . . . .
Section 1076 was supported by both conservatives and liberals. Sen. Carl Levin (D-Mich.), the ranking Democratic member on the Senate Armed Services Committee, co-wrote the provision along with committee chairman Sen. John Warner (R-Va.). Sen. Ted Kennedy openly endorsed it, and Rep. Duncan Hunter (R-Calif.), then-chairman of the House Armed Services Committee, was an avid proponent. . . .
Sen. Patrick Leahy (D-Vt.), the ranking Democrat on the Senate Judiciary Committee, warned on Sept. 19 that "we certainly do not need to make it easier for Presidents to declare martial law," but his alarm got no response. Ten days later, he commented in the Congressional Record: "Using the military for law enforcement goes against one of the founding tenets of our democracy." Leahy further condemned the process, declaring that it "was just slipped in the defense bill as a rider with little study. Other congressional committees with jurisdiction over these matters had no chance to comment, let alone hold hearings on, these proposals."
