The Justice Department concluded in October 2001 that military operations combating terrorism inside the United States are not limited by Fourth Amendment protections against unreasonable searches and seizures, in one of several secret memos containing new and controversial assertions of presidential power. The memo, sent on Oct. 23, 2001, to the Defense Department and the White House by the Office of Legal Counsel, focused on the rules governing any deployment of U.S. forces inside the country in the event of further large-scale terrorist activities." Administration officials declined to detail what domestic military operations were being contemplated at the time. The memo has not been formally withdrawn. The Fourth Amendment assertion is one of several far-reaching legal arguments revealed by the disclosure Tuesday of a 2003 Justice Department memo that authorized harsh military interrogations. In its footnotes, asides and central text, that 81-page memo asserted nearly unlimited presidential powers during a time of war. The document disclosed, for example, that the administration's top lawyers had declared that the president has unfettered power to seize oceangoing ships as commander in chief; that Congress has no ability to pass legislation governing the interrogations of enemy combatants; and that federal laws prohibiting assault and other crimes did not apply to military interrogators. One section discussed to what extent the president might be allowed to legally maim a prisoner, such as through the use of a "scalding, corrosive, or caustic substance." A footnote argued that Fifth Amendment guarantees of due-process rights "do not address actions the Executive takes in conducting a military campaign against the Nation's enemies."
