The Obama administration threw open the curtain on years of Bush-era secrets Monday, revealing anti-terror memos that claimed exceptional search-and-seizure powers and divulging that the CIA destroyed nearly 100 videotapes of interrogations and other treatment of terror suspects. The Justice Department released nine legal opinions showing that, following the Sept. 11, 2001, terrorist attacks, the Bush administration determined that certain constitutional rights would not apply during the coming fight. Within two weeks, government lawyers were already discussing ways to wiretap U.S. conversations without warrants. An October 2001 memo by the Justice Department's John Yoo authorized the use of the U.S. military within the United States in combating terrorists. Yoo defined the 9/11 attacks as war" and therefore concluded the President could employ the military domestically in a "military action" rather than a police action. Under Posse Comitatus Act, the American armed forces are forbidden from operating domestically. A March 2003 memo gave the President broad powers to transfer captured al Qaeda and Taliban prisoners to third countries. It also stipulated that the torture provisions of the Geneva Convention did not apply, because these prisoners were "non state" enemy combatants and therefore not entitled to Geneva protections. The Obama administration also acknowledged in court documents Monday that the CIA destroyed 92 videos involving terror suspects, including interrogations - far more than had been known.
