How Ali Soufan, an FBI agent, got Abu Zubaydah to talk without torture.

The arguments at the CIA safe house were loud and intense in the spring of 2002. Inside, a high-value terror suspect, Abu Zubaydah, was handcuffed to a gurney. He had been wounded during his capture in Pakistan and still had bullet fragments in his stomach, leg and groin. Agency operatives were aiming to crack him with rough and unorthodox interrogation tactics—including stripping him nude, turning down the temperature and bombarding him with loud music. But one impassioned young FBI agent wanted nothing to do with it. He tried to stop them.

The agent, Ali Soufan, was known as one of the bureau's top experts on Al Qaeda. He also had a reputation as a shrewd interrogator who could work fluently in both English and Arabic. Soufan yelled at one CIA contractor and told him that what he was doing was wrong, ineffective and an affront to American values. At one point, Soufan discovered a dark wooden "confinement box" that the contractor had built for Abu Zubaydah. It looked, Soufan recalls, "like a coffin." The mercurial agent erupted in anger, got on a secure phone line and called Pasquale D'Amuro, then the FBI assistant director for counterterrorism. "I swear to God," he shouted, "I'm going to arrest these guys!"

D'Amuro and other officials were alarmed at what they heard from Soufan. They fretted about the political consequences of abusive interrogations and the Washington blowback they thought was inevitable, say two high-ranking FBI sources who asked not to be identified discussing internal matters. According to a later Justice Department inspector general's report, D'Amuro warned FBI Director Bob Mueller that such activities would eventually be investigated. "Someday, people are going to be sitting in front of green felt tables having to testify about all of this," D'Amuro said, according to one of the sources.

Mueller ordered Soufan and a second FBI agent home. He then directed that bureau personnel no longer participate in CIA interrogations. In the corridors of the White House, Justice Department and U.S. intelligence agencies, heated debates ensued. Three months later, on Aug. 1, 2002, Justice lawyers issued a chilling memo blessing everything the CIA contractors had proposed—including waterboarding, or simulated drowning, a ghoulish technique that was administered to Abu Zubaydah 83 times.

This was a decisive moment in the campaign against Al Qaeda—the point at which, in the eyes of many critics, the Bush administration took a fateful step away from the rule of law. The administration, believing it faced an extraordinary threat that justified extreme measures, shifted toward what former vice president Dick Cheney once grimly called "the dark side." But the debates that began in that spring of 2002 never really ended.

Last week Soufan, 37, now a security consultant who spends most of his time in the Middle East, decided to tell the story of his involvement in the Abu Zubaydah interrogations publicly for the first time. In an op-ed in The New York Times and in a series of exclusive interviews with NEWSWEEK, Soufan described how he, together with FBI colleague Steve Gaudin, began the interrogation of Abu Zubaydah. They nursed his wounds, gained his confidence and got the terror suspect talking. They extracted crucial intelligence—including the identity of Khalid Sheikh Mohammed as the architect of 9/11 and the dirty-bomb plot of Jose Padilla—before CIA contractors even began their aggressive tactics....................
