San Francisco Chronicle on Martial Law

Since 9/11, and seemingly without the notice of most Americans, the federal government has assumed the authority to institute martial law, arrest a wide swath of dissidents (citizen and noncitizen alike), and detain people without legal or constitutional recourse in the event of "an emergency influx of immigrants in the U.S., or to support the rapid development of new programs."

Beginning in 1999, the government has entered into a series of single-bid contracts with Halliburton subsidiary Kellogg, Brown and Root (KBR) to build detention camps at undisclosed locations within the United States. The government has also contracted with several companies to build thousands of railcars, some reportedly equipped with shackles, ostensibly to transport detainees.
