President Bush set broad legal boundaries for the CIA's harsh interrogation of terrorism suspects yesterday, allowing the intelligence agency to resume a program that was suspended last year after criticism that it violated U.S. and international law. In an executive order lacking any details about actual interrogation techniques, Bush said the CIA program will now comply with a Geneva Conventions prohibition against outrages upon personal dignity, in particular humiliating and degrading treatment." Two administration officials said that suspects now in U.S. custody could be moved immediately into the "enhanced interrogation" program and subjected to techniques that go beyond those allowed by the U.S. military. Rights activists criticized Bush's order for failing to spell out which techniques are now approved or prohibited. "All the order really does is to have the president say, 'Everything in that other document that I'm not showing you is legal -- trust me,' " said Tom Malinowski of Human Rights Watch. The CIA interrogation guidelines are contained in a classified document. A senior intelligence official, asked whether this list includes such widely criticized methods as the simulated drowning known as "waterboarding," declined to discuss specifics but said "it would be very wrong to assume that the program of the past would move into the future unchanged." CIA detainees have also alleged they were left naked in cells for prolonged periods, subjected to sensory and sleep deprivation and extreme heat and cold, and sexually taunted. A senior administration official briefing reporters yesterday said that any future use of "extremes of heat and cold" would be subject to a "reasonable interpretation . . . we're not talking about forcibly induced hypothermia."
