chained to a wall for more than a month. At least 39 detainees who were once held by the CIA in secret detention remain "disappeared," according to Off the Record, a report jointly published June 7, 2007 by six leading human rights groups, including Amnesty International, the Center for Constitutional Rights, the Center for Human Rights and Global Justice, and Human Rights Watch. Spokesmen say that their report: reveals the extent to which the United States has illegally used "proxy detention" to empty its secret sites and demonstrates that far from targeting the "worst of the worst," the system sweeps up low-level detainees and even involves the detention of the wives and children of the "disappeared," in violation of their human rights.

The practice, he wrote, 'was deceptive, contrary to Army doctrine, and in violation of international law'. When news of a detainee known only as Triple X became known to the public in late 2003, U.S. Secretary of Defense Donald Rumsfeld was questioned about him. Rumsfeld was evasive, and speculated about why someone would want to keep a prisoner hidden from the Red
