A report by the Senate Select Committee on Intelligence describes a years-long CIA effort to justify its harsh interrogation tactics. Even before the agency interrogated anyone, the CIA’s lawyers wrote in a November 2001 memo that it would be easier to defend against torture allegations if the tactics saved lives. Here are eight cases cited in the report where the CIA made the case that its tactics thwarted plots and led to the capture of terrorists, and how the committee’s report undercut those accounts.

The CIA acknowledged that its statements were sometimes inaccurate or speculative, and promised to do better in the future. But it said the committee’s report unfairly dismissed the value of intelligence gathered from detainees, particularly in understanding al-Qaida and tracking Osama bin Laden.

Killing of Osama bin Laden

The Case: No counterterrorism mission was more successful or higher profile than the secret raid that killed Osama bin Laden in 2011. Almost immediately, CIA officials began telling Congress that its interrogation program led them to a secretive courier, Abu Ahmed al-Kuwaiti, who in turn led the CIA to the doorstep of the world’s most-wanted terrorist.

Committee’s Conclusion: But in page after page of previously classified evidence, the committee calls those statements inaccurate. The report shows that, as early as 2002, the CIA received a wealth of evidence about the courier, including his alias and his association with bin Laden, as well as a physical description and family connections that would later prove crucial in finding him. By the end of the year, the CIA was wiretapping his phone number and email address and had recordings of his voice.

The linchpin in the hunt for the courier was a detainee named Hassan Ghul. But Ghul was cooperative from the outset. One officer said he "sang like a tweetie bird." Ghul spoke expansively about the courier, describing him as bin Laden’s closest assistant. Despite the cooperation, the CIA decided to torture Ghul, subjecting him to sleep deprivation and stress positions. He hallucinated. His heart fell out of rhythm. But he provided "no actionable threat information."

Nevertheless, after the bin Laden raid, the CIA provided Congress with a document listing Ghul as a detainee who had been subjected to enhanced interrogation and provided valuable intelligence on bin Laden’s courier. The document did not make clear that the valuable intelligence came before the harsh tactics.

From Pages 379-380 of the Report: "Within days of the raid on UBL’s compound, CIA officials represented that CIA detainees provided the ‘tipoff’ information on Abu Ahmad al-Kuwaiti. A review of CIA records found that the initial intelligence obtained, as well as the information the CIA identified as the most critical — or the most valuable — on Abu Ahmad al-Kuwaiti, was not related to the use of the CIA’s enhanced interrogation techniques."

Thwarting of Dirty Bomb and Capture of Josi Padilla

The Case: Josi Padilla, who was accused of plotting a radiological dirty bomb attack inside the United States, was one of the first American citizens designated an "enemy combatant." The Bush administration credited the interrogation of Abu Zubaydah with uncovering the plot and leading investigators to Padilla. His arrest has been held up for years as proof that waterboarding and other tactics worked.

Committee’s Conclusion: But Abu Zubaydah’s information on Padilla was sketchy, and he provided it well before he was waterboarded. Padilla, in fact, was arrested in May 2002, three months before the CIA interrogation program began.

For all the publicity the Bush administration gave Padilla, the committee revealed that the government never took his dirty bomb plot seriously. It was based on a satirical Internet article titled "How to Make an H-Bomb," and the plot involved swinging a bucket full of uranium over one’s head for 45 minutes. One internal CIA email declared that such a plot would most likely kill Padilla but "would definitely not result in a nuclear explosive device." Another called Padilla "a petty criminal" and described the dirty bomb plot as "lore."

From Page 230 of the Report: "A review of CIA operational cables and other CIA records found that the use of the CIA’s enhanced interrogation techniques played no role in the identification of ‘Jose Padilla’ or the thwarting of the Dirty Bomb or Tall Buildings plotting."

Thwarting of the Karachi Plots

The Case: President George W. Bush credited the CIA interrogation program with helping to prevent an attack on the U.S. Consulate in Karachi, Pakistan. The tip can be traced back to the interrogations of Ammar al-Baluchi and Khallad bin Attash, who were subjected to harsh CIA interrogations in May 2003. Intelligence reports from those interrogations state that al-Qaida was plotting attacks on the consulate and other Western targets in Karachi.

Committee’s Conclusion: But according to the committee report, the CIA already knew that information. Baluchi and bin Attash had provided it weeks earlier to Pakistani officials, who then relayed it to the CIA. So when the intelligence report on the Karachi plot was issued, CIA officials in Pakistan were nonplussed. They issued a cable saying they "had become aware of most of this reporting" already. Security at the consulate had been increased based on earlier threats, the officers reported.

Weeks later, when Khalid Sheikh Mohammed — after being subjected to waterboarding — discussed the Karachi plot, it came as no surprise to CIA officials, who again reported that they already knew about it.

From Page 239 of the Report: "CIA records indicate the CIA became aware of the initial plotting as early as September 2002, and that it was disrupted in April 2003, when the remaining plot leaders were arrested in a unilateral operation by Pakistani authorities."

Thwarting of ‘Second Wave’ Plot and Discovery of Al Ghurabaa Group

The Case: In 2006, the White House announced that the Sept. 11, 2001, attacks had been conceived as an attack on two fronts, with a "second wave" planned on the West Coast. The plot, as described by Bush, involved hijacking an airplane and crashing it into Library Tower in Los Angeles.

Committee’s Conclusion: In a memo to the Justice Department, the CIA credited the waterboarding of Mohammed with uncovering this plot. But the committee report revealed that the CIA learned about the plot in January 2002 with the arrest of Masran bin Arshad, a Malaysian national who was involved. Mohammed confirmed the existence of the plot after being tortured, to the frustration of CIA interrogators who said he was confirming only what they already knew.

From Pages 246-247 of the Report: "The Second Wave plotting was disrupted with the arrest and identification of key individuals … unrelated to any reporting acquiring during or after the use of the CIA’s enhanced interrogation techniques against CIA detainees. Likewise, the al-Ghuraba group was identified by a detainee who was not in CIA custody."

Identification, Capture and Arrest of Iyman Faris

The Case: In 2003, the Justice Department charged an Ohio truck driver, Iyman Faris, in an al-Qaida plot to destroy the Brooklyn Bridge by cutting its suspension cables. In government briefings, CIA officials repeatedly credited the interrogation program with uncovering the plot and identifying Faris.

Committee’s Conclusion: The committee report revealed that it was actually a court-approved wiretap of another American suspect, Majid Khan, that prompted the FBI investigation into Faris. Khan’s capture and interrogation by a foreign government — without any harsh tactics, according to CIA documents — led to the identification of Faris as an al-Qaida member.

Later, after being tortured, Mohammed identified a photo of Faris but could not remember his name. He said that he had once tasked Faris with finding tools to loosen the bolts of American suspension bridges, but that Faris had been unable to do so. The FBI had already been following Faris at that point, and when agents approached him, he talked voluntarily, the report showed.

Separately, CIA officials played down the likelihood of the bridge attack. "We risk making ourselves look silly if the best we can do is the Brooklyn Bridge," one official wrote in 2005.

From Page 276 of the Report: "Iyman Faris was identified, investigated, and linked directly to al-Qaida prior to any mention of Iyman Faris by KSM or any other CIA detainee. When approached by law enforcement, Iyman Faris voluntarily provided information and made self-incriminating statements."

Thwarting of the Heathrow Airport and Canary Wharf Plot

The Case: After the Sept. 11 attacks, Mohammed hoped to use hijacked airplanes to attack Heathrow Airport and Canary Wharf, a business district in London. The CIA credited its enhanced interrogation of him with uncovering the plot.

Committee’s Conclusion: But the committee report shows that the CIA knew that al-Qaida had targeted Heathrow months before Mohammed was captured and waterboarded. The plot was labeled "not imminent" because al-Qaida had not identified pilots for the mission. And the plot was disrupted in full with the capture of Ramzi bin al-Shibh, Mohammed and others.

From Page 295 of the Report: "A review of records indicates that the Heathrow Airport and Canary Wharf plotting had not progressed beyond the initial planning stages when the operation was fully disrupted with the detentions of Ramzi bin al-Shibh, KSM, Ammar al-Baluchi, and Khallad bin Attash. None of these individuals were captured as a result of reporting obtained during or after the use of the CIA’s enhanced interrogation techniques against CIA detainees."

Capture of Ramzi bin al-Shibh

The Case: The Bush administration said that the capture of Abu Zubaydah and his subsequent interrogation, which included waterboarding, led to the capture of bin al-Shibh, another senior al-Qaida operative. A senior CIA official told Congress that Abu Zubaydah "led us to Ramzi bin al-Shibh."

Committee’s Conclusion: The committee report found no evidence of that. "C.I.A. records indicate that Ramzi bin al-Shibh was captured unexpectedly" during raids in Pakistan in which authorities were searching for someone else. While CIA cables indicate that Abu Zubaydah did reveal information on bin al-Shibh during his waterboarding, interrogation reports cited by the committee revealed that Abu Zubaydah had already revealed that information to the FBI — without being tortured.

From Page 320 of the Report: "The information Abu Zubaydah provided while being subjected to the CIA’s enhanced interrogation techniques was described by CIA interrogators as ‘significant new details.’ However, the information provided by Abu Zubaydah was similar to information Abu Zubaydah provided prior to the application of the CIA’s enhanced interrogation techniques, or was otherwise already known to the CIA."

Capture of Khalid Sheikh Mohammed

The Case: Bush credited the interrogation of Abu Zubaydah and bin al-Shibh with providing "information that helped in the planning and execution of the operation that captured Khalid Shaikh Mohammed." The CIA also credited its interrogation of Abu Zubaydah with revealing Mohammed as the mastermind of the Sept. 11 attacks.

"It was Abu Zubaydah, early in his detention, who identified K.S.M. as the mastermind of 9/11," Michael Hayden, director of the CIA, told Congress. "Until that time, K.S.M. did not even appear in our charge of key al-Qaida members and associates."

Committee’s Conclusion: But CIA documents show that Mohammed was a suspect in the Sept. 11 attacks almost immediately.

Also, in a section of the report that was heavily redacted by the CIA, the committee showed that a source — referred to as Asset X — led the CIA to Mohammed. The source sent his CIA handler a text message that read: "I M W KSM." The informant, seeking a $25 million reward, led the agency to Mohammed.

From Page 327 of the Report: "Contrary to CIA representations, there are no CIA records to support the assertion that Abu Zubaydah, Ramzi bin al-Shibh, or any other CIA detainee played any role in the ‘the planning and execution of the operation that captured Khalid Sheikh Mohammed.’"
