CIA chiefs tell Obama: Let it go

       Seven former heads of the CIA urged President Barack Obama on Friday to end the probe into allegations of abuse of prisoners held by the agency, arguing that it would hamper intelligence operations.
       US Attorney-General Eric Holder last month named a prosecutor to examine whether criminal charges should be filed against CIA interrogators or contractors for going beyond approved interrogation methods, including using a power drill and death threats to scare detainees.
       The former CIA chiefs countered that the cases had already been investigated during the Bush administration and lawyers had declined to prosecute all but one contractor.
       "This approach will seriously damage the willingness of intelligence officers to take risks to protect the country,"they said in the letter."In our judgement,such risk-taking is vital to success in the long and difficult fight against terrorists who continue to threaten us."
       The letter to Mr Obama was signed by three CIA directors under president George W. Bush - Michael Hayden,Porter Goss and George Tenet - as well as by John Deutch, James Woolsey,William Webster and James Schlesinger,who dates to the Nixon administration.
       Mr Obama has said the matter was up to Mr Holder, who decided in late August to reopen the cases because "it is clear to me that this review is the only responsible course of action".
       The Washington Post has reported that the Justice Department review would focus on only a very small number of cases, including one in which an Afghan prisoner died at a secret CIA facility in Afghanistan seven years ago.
       Bush administration officials, including former vice-president Dick Cheney,have repeatedly defended their actions.
       The former CIA directors warned that Mr Holder's decision "creates an atmosphere of continuous jeopardy" for those involved and that there was no reason to believe the investigation would be narrowly focused.
       They also warned that releasing more details about interrogation methods could help al-Qaeda operatives elude US intelligence efforts.
       "Disclosures about CIA collection operations have and will continue to make it harder for intelligence officers to maintain the momentum of operations that have saved lives and helped protect America from further attacks," they said.
       Mr Cheney, who has called the investigation "political", has made similar arguments about the interrogation tactics saving lives and protecting the country,though his critics say there is no proof.
       A CIA inspector general's report detailing the harsh interrogation techniques noted that they did not succeed.
       A spokesman for Mr Holder said the attorney-general named a prosecutor to investigate after receiving a recommendation from the Justice Department's ethics office and other information.
       "The attorney-general's decision to order a preliminary review into this matter was made in line with his duty to examine the facts and to follow the law,"the spokesman said."The Department of Justice will not prosecute anyone who acted in good faith and within the scope of the legal guidance given by the Office of Legal Counsel regarding the interrogation of detainees."
