On January 27th, President Bush, in an interview with the Times, assured the world that “torture is never acceptable, nor do we hand over people to countries that do torture.” Maher Arar, a Canadian engineer who was born in Syria, was surprised to learn of Bush’s statement. Two and a half years ago, American officials, suspecting Arar of being a terrorist, apprehended him in New York and sent him back to Syria, where he endured months of brutal interrogation, including torture. When Arar described his experience in a phone interview recently, he invoked an Arabic expression. The pain was so unbearable, he said, that “you forget the milk that you have been fed from the breast of your mother.”

Arar, a thirty-four-year-old graduate of McGill University whose family emigrated to Canada when he was a teen-ager, was arrested on September 26, 2002, at John F. Kennedy Airport. He was changing planes; he had been on vacation with his family in Tunisia, and was returning to Canada. Arar was detained because his name had been placed on the United States Watch List of terrorist suspects. He was held for the next thirteen days, as American officials questioned him about possible links to another suspected terrorist. Arar said that he barely knew the suspect, although he had worked with the man’s brother. Arar, who was not formally charged, was placed in handcuffs and leg irons by plainclothes officials and transferred to an executive jet. The plane flew to Washington, continued to Portland, Maine, stopped in Rome, Italy, then landed in Amman, Jordan.

During the flight, Arar said, he heard the pilots and crew identify themselves in radio communications as members of “the Special Removal Unit.” The Americans, he learned, planned to take him next to Syria. Having been told by his parents about the barbaric practices of the police in Syria, Arar begged crew members not to send him there, arguing that he would surely be tortured. His captors did not respond to his request; instead, they invited him to watch a spy thriller that was aired on board.

Ten hours after landing in Jordan, Arar said, he was driven to Syria, where interrogators, after a day of threats, “just began beating on me.” They whipped his hands repeatedly with two-inch-thick electrical cables, and kept him in a windowless underground cell that he likened to a grave. “Not even animals could withstand it,” he said. Although he initially tried to assert his innocence, he eventually confessed to anything his tormentors wanted him to say. “You just give up,” he said. “You become like an animal.”

A year later, in October, 2003, Arar was released without charges, after the Canadian government took up his cause. Imad Moustapha, the Syrian Ambassador in Washington, announced that his country had found no links between Arar and terrorism. Arar, it turned out, had been sent to Syria on orders from the U.S. government, under a secretive program known as “extraordinary rendition.” This program had been devised as a means of extraditing terrorism suspects from one foreign state to another for interrogation and prosecution. Critics contend that the unstated purpose of such renditions is to subject the suspects to aggressive methods of persuasion that are illegal in America—including torture.

Arar is suing the U.S. government for his mistreatment. “They are outsourcing torture because they know it’s illegal,” he said. “Why, if they have suspicions, don’t they question people within the boundary of the law?”

Rendition was originally carried out on a limited basis, but after September 11th, when President Bush declared a global war on terrorism, the program expanded beyond recognition—becoming, according to a former C.I.A. official, “an abomination.” What began as a program aimed at a small, discrete set of suspects—people against whom there were outstanding foreign arrest warrants—came to include a wide and ill-defined population that the Administration terms “illegal enemy combatants.” Many of them have never been publicly charged with any crime. Scott Horton, an expert on international law who helped prepare a report on renditions issued by N.Y.U. Law School and the New York City Bar Association, estimates that a hundred and fifty people have been rendered since 2001. Representative Ed Markey, a Democrat from Massachusetts and a member of the Select Committee on Homeland Security, said that a more precise number was impossible to obtain. “I’ve asked people at the C.I.A. for numbers,” he said. “They refuse to answer. All they will say is that they’re in compliance with the law.”

Although the full scope of the extraordinary-rendition program isn’t known, several recent cases have come to light that may well violate U.S. law. In 1998, Congress passed legislation declaring that it is “the policy of the United States not to expel, extradite, or otherwise effect the involuntary return of any person to a country in which there are substantial grounds for believing the person would be in danger of being subjected to torture, regardless of whether the person is physically present in the United States.”

The Bush Administration, however, has argued that the threat posed by stateless terrorists who draw no distinction between military and civilian targets is so dire that it requires tough new rules of engagement. This shift in perspective, labelled the New Paradigm in a memo written by Alberto Gonzales, then the White House counsel, “places a high premium on . . . the ability to quickly obtain information from captured terrorists and their sponsors in order to avoid further atrocities against American civilians,” giving less weight to the rights of suspects. It also questions many international laws of war. Five days after Al Qaeda’s attacks on the World Trade Center and the Pentagon, Vice-President Dick Cheney, reflecting the new outlook, argued, on “Meet the Press,” that the government needed to “work through, sort of, the dark side.” Cheney went on, “A lot of what needs to be done here will have to be done quietly, without any discussion, using sources and methods that are available to our intelligence agencies, if we’re going to be successful. That’s the world these folks operate in. And so it’s going to be vital for us to use any means at our disposal, basically, to achieve our objective.”

The extraordinary-rendition program bears little relation to the system of due process afforded suspects in crimes in America. Terrorism suspects in Europe, Africa, Asia, and the Middle East have often been abducted by hooded or masked American agents, then forced onto a Gulfstream V jet, like the one described by Arar. This jet, which has been registered to a series of dummy American corporations, such as Bayard Foreign Marketing, of Portland, Oregon, has clearance to land at U.S. military bases. Upon arriving in foreign countries, rendered suspects often vanish. Detainees are not provided with lawyers, and many families are not informed of their whereabouts.

The most common destinations for rendered suspects are Egypt, Morocco, Syria, and Jordan, all of which have been cited for human-rights violations by the State Department, and are known to torture suspects. To justify sending detainees to these countries, the Administration appears to be relying on a very fine reading of an imprecise clause in the United Nations Convention Against Torture (which the U.S. ratified in 1994), requiring “substantial grounds for believing” that a detainee will be tortured abroad. Martin Lederman, a lawyer who left the Justice Department’s Office of Legal Counsel in 2002, after eight years, says, “The Convention only applies when you know a suspect is more likely than not to be tortured, but what if you kind of know? That’s not enough. So there are ways to get around it.”
