Aghast at the Bush Administration

The Bush Administration may have a concealed internal legal opinion which, at their whim, makes any action of the National Security Agency, by fiat, legal, overruling the Fourth Amendment.   

... our Office recently concluded that the Fourth Amendment had no application to domestic military operations. See Memorandum for Alberto R. Gonzales, Counsel to the President, and William J. Haynes, II, General Counsel, Department of Defense, from John C. Yoo, Deputy Assistant Attorney General and Robert J. Delahunty, Special Counsel, Re: Authority for Use of Military Force to Combat Terrorist Activities Within the United States at 25 (Oct 23, 2001). (emphasis added)
