WASHINGTON -- The Obama administration launched a criminal investigation Monday into harsh questioning of detainees during President George W. Bush's war on terrorism, revealing CIA interrogators' threats to kill one suspect's children and to force another to watch his mother sexually assaulted.
At the same time, President Obama ordered changes in future interrogations, bringing in agencies in addition to the CIA under the direction of the FBI and supervised by the national security adviser. The administration pledged questioning would be controlled by the Army Field Manual and said the White House would keep its hands off the professional investigators doing the work.
Despite the announcement of the criminal probe, several Obama spokesmen said that on the subject of detainee interrogation Obama "wants to look forward, not back" at Bush tactics. They said decisions on any prosecutions would be up to Attorney General Eric Holder, not the White House.
Monday's five-year-old report by the CIA's inspector general, newly declassified and released under a federal court's orders, described severe tactics used by interrogators on terror suspects after the Sept. 11 attacks. Seeking information about possible further attacks, interrogators threatened one detainee with a gun and a power drill, choked another and tried to frighten a third with a mock execution of another prisoner.
Holder said he had chosen a veteran prosecutor to determine whether any CIA officers or contractors should face criminal charges for crossing the line on rough but permissible tactics.
Former CIA director Michael Hayden, appointed by President Bush in 2006, expressed dismay by the prospect of prosecutions for CIA officers. He noted that career prosecutors have already reviewed and declined to prosecute the alleged abuses.
Obama has said interrogators would not face charges if they followed legal guidelines, but the report by the CIA's inspector general said they went too far -- even beyond what was authorized under Justice Department legal memos that have since been withdrawn and discredited. The report also suggested some questioners knew they were crossing a line.
"Ten years from now we're going to be sorry we're doing this [but] it has to be done," one unidentified CIA officer was quoted as saying, predicting the questioners would someday have to appear in court to answer for such tactics.
The report concluded the CIA used "unauthorized, improvised, inhumane" practices in questioning "high-value" terror suspects.
Monday's documents represent the largest single release of information about the Bush administration's once-secret system of capturing terrorism suspects and interrogating them in overseas prisons.
White House officials said they plan to continue the controversial practice of rendition of suspects to foreign countries, though they said that in future cases they would more carefully check to make sure such suspects are not tortured.
In one instance cited in the new documents, Abd al-Nashiri, the man accused of being behind the 2000 USS Cole bombing, was hooded, handcuffed and threatened with an unloaded gun and a power drill. The unidentified interrogator also threatened al-Nashiri's mother and family, implying they would be sexually abused in front of him, according to the report.
The interrogator denied making a direct threat.
Another interrogator told alleged Sept. 11 mastermind Khalid Sheikh Mohammed, "if anything else happens in the United States, ‘We're going to kill your children,"' one veteran officer said in the report.
Death threats violate anti-torture laws.
In another instance, an interrogator choked off the carotid artery of a detainee until he started to pass out, then shook him awake. He did this three times. The interrogator, a CIA debriefer accustomed to questioning willing subjects, said he had only recently been trained to conduct interrogations.
Top Republican senators said they were troubled by the decision to begin a new investigation, which they said could weaken U.S. intelligence efforts. Sen. Patrick Leahy, the Democratic chairman of the Judiciary Committee, said the revelations showed the Bush administration went down a "dark road of excusing torture."
Investigators credited the detention-and-interrogation program for developing intelligence that prevented multiple attacks against Americans. One CIA operative interviewed for the report said the program thwarted al-Qaida plots to attack the U.S. Embassy in Pakistan, derail trains, blow up gas stations and cut the suspension line of a bridge.
"In this regard, there is no doubt that the program has been effective," investigators wrote, backing an argument by former Vice President Dick Cheney and others that the program saved lives.
But the inspector general said it was unclear whether so-called "enhanced interrogation" tactics contributed to that success. Those tactics include waterboarding, a simulated drowning technique that the Obama administration says is torture. Measuring the success of such interrogation is "a more subjective process and not without some concern," the report said.
The report describes at least one mock execution, which would also violate U.S. anti-torture laws. To terrify one detainee, interrogators pretended to execute the prisoner in a nearby room. A senior officer said it was a transparent ruse that yielded no benefit.
As the report was released, Attorney General Holder appointed prosecutor John Durham to open a preliminary investigation into the claims of abuse. Durham is already investigating the destruction of CIA interrogation videos and now will examine whether CIA officers or contractors broke laws in the handling of suspects.
The administration also announced Monday that all U.S. interrogators will follow the rules for detainees laid out by the Army Field Manual. The manual, last updated in September 2006, prohibits forcing detainees to be naked, threatening them with military dogs, exposing them to extreme heat or cold, conducting mock executions, depriving them of food, water, or medical care, and waterboarding.
Formation of the new interrogation unit for "high-value" detainees does not mean the CIA is out of the business of questioning terror suspects, deputy White House press secretary Bill Burton told reporters covering the vacationing president on Martha's Vineyard in Massachusetts.
Burton said the unit will include "all these different elements under one group" and will be located at the FBI headquarters in Washington.
The structure of the new unit the White House is creating would be significantly broader than under the Bush administration, when the CIA had the lead and sometimes exclusive role in questioning al-Qaida suspects.
Obama campaigned vigorously against Bush administration interrogation practices in his successful run for the presidency. He has said more recently he didn't particularly favor prosecuting officials in connection with instances of prisoner abuse.
Burton said Holder "ultimately is going to make the decisions."
CIA Director Leon Panetta said in an e-mail message to agency employees Monday that he intended "to stand up for those officers who did what their country asked and who followed the legal guidance they were given. That is the president's position, too," he said.
Panetta said some CIA officers have been disciplined for going beyond the methods approved for interrogations by the Bush-era Justice Department. Just one CIA employee -- contractor David Passaro-- has been prosecuted for detainee abuse.
