NOUAKCHOTT, Mauritania — Mohamedou Ould Slahi is almost clinical as he recalls details of the torture he endured in the summer of 2003 at Guantánamo Bay.

There were the guards who menaced him with attack dogs and beat him so badly that they broke his ribs. The troops who shackled him, blasted him with heavy metal music and strobe lights, or drenched him in ice water to deny him sleep for months on end. The mind-numbing isolation in a darkened cell without his Quran. The female guards who exposed themselves and touched him sexually in an effort to undermine his adherence to Islam.

But what left Slahi in utter despair, he said, was the interrogator who tried to threaten him into acknowledging that he was complicit in plotting a terrorist attack.

“If you don’t admit to it, we are going to kidnap your mother, rape her,” the interrogator said, by Slahi’s account.

“I remember telling them: ‘This is unfair. This is not fair,’” Slahi recalled. The interrogator, he said, responded: “I’m not looking for justice. I’m looking to stop planes from hitting buildings in my country.”

To which Slahi said he replied, “You need to get those people, not me.”

Today, Slahi, 50, is a free man in Mauritania, his homeland in West Africa, after nearly 15 years as a detainee, an early portion of that time with the threat of a death-penalty trial hanging over him.

In the end, he was released in 2016 without ever being charged, the confessions he made under duress recanted, a proposed case against him deemed by the prosecutor to be worthless in court because of the brutality of the interrogation.

“I was very naive, and I didn’t understand how America works,” Slahi said.

For the United States, as for Slahi, the legacy of the torture remains complex and multifaceted two decades after 9/11 led the George W. Bush administration to set aside legal and moral constraints in the name of national security.

The United States has long since stopped employing the so-called enhanced interrogation techniques used in what studies have concluded was a fruitless or counterproductive effort to extract life-saving information from detainees in secret CIA prisons and at Guantánamo Bay.

But the choice to turn to government-sanctioned torture remains a stain on the country’s reputation, undercutting its authority to confront repression elsewhere. Even today, some former Bush administration officials risk questioning when travelling to Europe by investigators invoking the United Nations Convention Against Torture.

After his first meeting with President Joe Biden in June, Russian President Vladimir Putin reminded journalists that Guantánamo remained open and that the CIA had carried out torture in secret foreign prisons. “Is that human rights?” he asked.

The use of torture is complicating efforts to bring the five men who are accused of plotting 9/11 to justice.

“There was torture,” said Adele Welty, whose son Timothy, a firefighter, died in New York on Sept. 11, 2001. She has come to question whether the military commissions at Guantánamo can deliver justice.

“The fact that my country could do that is so barbaric. It really bothers me,” she said. “What kind of people are we that we could do that to other human beings, and did we really believe that what they were saying in response to the torture was real, or were they just saying it to stop the torture?”

Stuart Couch, a former Marine prosecutor whose job was to put Slahi on trial at Guantánamo Bay — but who refused once he learned what the military had done to him — said the United States still suffered from what he called the “Jack Bauer effect”: the belief that you could beat a confession out of a suspect, save the day and emerge heroic, like the star of the TV thriller ‘24’, which aired on Fox from 2001 to 2010.

Slahi lived that misconception.

He now has a measure of fame. His bestselling memoir, ‘Guantánamo Diary’, was released in a film version, ‘The Mauritanian’. Although he is often denied visas for travel, he recently made a trip to London, where he took part in a literary reading and was hosted at a party by Kevin Macdonald, director of the movie.

A software engineer, Slahi has two phones, a laptop and Wi-Fi in the home he built since his release. Isolated for long stretches during his imprisonment, he carries on multiple conversations across the world these days through texts, video chats and phone calls.

On one level, his is a hopeful story.

“I wholeheartedly forgive everyone who wronged me during my detention,” he said in a YouTube message to the world soon after his release. “I forgive, because forgiveness is my inexhaustible resource.”

But the effects of what he endured at Guantánamo are by no means behind him.

Slahi exhibits signs of post-traumatic stress disorder: insomnia, inattentiveness, hyper-attentiveness, at times scattered thinking. He has hearing deficits probably related to the screeching heavy metal music that guards blasted to keep him awake and chronic back pain from sciatica that can be attributed to months of shackling.

He has memory lapses of a certain period of detention and vivid recollections of other times. Discussing his torture, he juxtaposed the accounts of his abuse at Guantánamo with renditions of songs he remembered hearing there: Drowning Pool’s ‘Let the Bodies Hit the Floor’ to deprive him of sleep, and a Justin Timberlake tune, ‘Señorita’, that soothed him as it seeped into his cell from a nearby guard post.

Slahi was one of two detainees whose torture at Guantánamo Bay was carried out under a program approved by then-Defence Secretary Donald Rumsfeld. The United States also sent 119 people into the CIA’s overseas network of secret prisons — including the accused plotters of 9/11 — where detainees were routinely sleep-deprived, shackled in excruciating ways and subjected to rectal abuse and other brutal treatment.

The CIA has acknowledged that three detainees were waterboarded. One died of abuse. Many more were brutalized in US or allied detention as interrogators improvised their own methods.

A comprehensive study by the Senate Select Intelligence Committee of the agency’s program concluded that the techniques did not save lives or disrupt terrorist plots and were not necessary, findings that the CIA disputed. (A lengthy executive summary of the report was made public in 2014, but the full report remains classified.)

Slahi’s story — laid out in interviews, testimony and congressional investigations — spans much of the 20 years in which the United States has variously obscured, acknowledged and dealt with the diplomatic and human fallout of the interrogation programs authorized by Bush and his team.

Slahi was a clever, curious son in a Bedouin family of 12 children who became the first in his family to study abroad. While working toward an engineering degree in Germany in the 1990s, he travelled to Afghanistan to train in the anti-Communist jihad at a time when the United States endorsed it. He was back in his native Mauritania on Sept. 11, 2001.

Intelligence analysts sifting through records after the attacks noted that he had received a call in late 1998 or early 1999 from a satellite phone used by Osama bin Laden. The call was about a family matter and came from a cousin who had been part of bin Laden’s inner circle and later fled to Mauritania, Slahi said.

US intelligence had also come to believe that Slahi had hosted three Muslim men in his home in Duisburg, Germany, for a night in November 1999. Among them were two of the 9/11 hijackers and Ramzi Binalshibh, who is accused of recruiting the so-called Hamburg cell of hijackers and is charged in a death-penalty case at Guantánamo. Slahi dismissed the encounter as so casual — a matter of offering hospitality to fellow Muslim travellers — that he said he did not remember the suspect named Ramzi when interrogators pressed him on it.

Investigators also noticed that Slahi had moved to Montreal in the winter of 1999 and prayed at the same mosque as Ahmed Ressam, an Algerian known as the millennium bomber for a failed plot to plant a bomb at Los Angeles International Airport on New Year’s Eve in 1999. Slahi was questioned by federal security forces in Canada and left for home after two months.

By 2001, the United States had persuaded the Mauritanian government to hand Slahi to Jordanian interrogators. He was then sent to Guantánamo Bay in August 2002, after what he described as a brief, brutal stay at a US military lockup in Bagram, Afghanistan.

At Guantánamo, guards and interrogators sought to break him both physically and psychologically. In one case, described by Slahi and other detainees, female guards exposed themselves and made sexual advances on him as he was shackled to a chair in an interrogation room. A male guard taunted him while a female guard took off her clothing.

“There was touching,” Slahi said. “So humiliating. So destroying.”

After months of interrogation, he admitted to plotting to blow up the CN Tower in Toronto — a confession he later said was forced, adding that he did not know before his interrogation that the skyscraper existed.

A trial was averted after Couch, then a lieutenant colonel in the Marine Corps, stumbled into a surreal scene at Guantánamo of another prisoner in an interrogation cell, nude, shackled to the floor and being blasted with heavy metal music. The colonel was shocked, did some digging and realized that Slahi’s confessions were obtained through what he concluded was cruel and unusual treatment.

Never charged, Slahi was kept as a prisoner in the war on terror, deemed too dangerous to release until his book, published in 2015 after his lawyers worked to have his writing declassified, put a spotlight on his case. A former Army guard, Steve Wood of Oregon, wrote the Obama administration’s interagency parole board that he considered Slahi so safe that he would gladly host him in his home.

US forces delivered Slahi to Mauritania just as he had been brought to Guantánamo: blindfolded and in shackles.

But although Slahi has been released, Guantánamo continues to reckon with what was done to other detainees still held there — not least the five men accused of helping to plot 9/11, including the alleged mastermind, Khalid Sheikh Mohammed, whom CIA contractors waterboarded 183 times at a secret prison in Poland.

The war court at Guantánamo, run by the US military, is meant to balance the need for secrecy with the rights of the accused.

To the frustration of families of the nearly 3,000 victims of the attack, the crimes of 9/11 have been rarely mentioned in nearly a decade of proceedings.

Rather, defence lawyers have effectively managed to put the CIA on trial as they have systematically sought to exclude evidence against the men — notably confessions they made months into their stays at Guantánamo — as a product of torture.

The lawyers for one defendant, Mustafa al-Hawsawi, who sits gingerly on a pillow in court because of pain from rectal abuse in CIA custody, argue that the case should be dismissed outright because of outrageous government conduct.

In an effort to speed up the proceedings — and perhaps to protect the identities of certain CIA employees — prosecutors have begun acknowledging that the United States tortured its captives in overseas prisons. They do not use the word, but they have read aloud in court from grisly descriptions of abuse to try to argue that defense lawyers have sufficient details to try to move either for dismissal of the charges or to exclude the death penalty if the defendants are convicted.

Prosecutors said in 2018 that they would stipulate to “anything tethered to reality” to avoid the national security struggle over declassifying certain details of what went on in the secret sites.

“We’re not going to quibble,” said one prosecutor, Jeffrey Groharing. “We’re not going to call witnesses and debate about whether Mr. Mohammed was waterboarded 183 times or 283 times. We, frankly, think that has little relevance to the commissions and the issues before it.”

The prosecutors appear to be banking on the idea that at this point, testimony about the treatment of the defendants will not lead the military jury in the case to acquit.

There are plenty of Americans who have not forgotten the choices made after 9/11. The country’s revulsion of torture dates to “the earliest days of the American Republic,” Judge Jed Rakoff, a federal judge in Manhattan, wrote in his recent book, ‘Why the Innocent Plead Guilty and the Guilty Go Free.’

“This is not the way a civilized colony, or later the United States as a whole, conducts itself,” he said. “I do think that fundamental legal qua moral approach was what was undercut in the wake of 9/11 by what happened in Guantánamo.”

Rakoff’s courthouse is a few blocks from ground zero. “What is still seared in my memory is watching people jump out of the windows of the World Trade Centre towers because the alternative is being burned to death inside,” he said in an interview. “One can never forget the atrocity of that attack. But it is also exactly when atrocities occur that the rule of law is put to the test.”

Only a handful of the men who were subject to the treatment approved by the Bush administration have been released and spoken publicly about the experience, with Slahi being prominent among them.

“I only have the law,” he said last month. “And if the law fails me, I’m done. There is nothing else left for me.”
