America's Treatment of Suspects in the War on Terror

At a news conference last week, President Bush was asked about an article in the New Yorker magazine. It details the CIA's so-called "enhanced interrogation" of terrorist suspects-- including Khalid Sheikh Mohammed, the confessed mastermind of September 11. Bush responded, "Haven't seen it. We don't torture." But the article says "the Red Cross described the agency's detention and interrogation methods as tantamount to torture and declared that American officials responsible for the abusive treatment could have committed serious crimes." Whatever one calls it, is such treatment a violation of international law? Does it provide useful information?
