WASHINGTON - The US Justice Department has allowed the Central Intelligence Agency (CIA) to torture jailed terror suspects, according to the three torture memos made public Thursday. "These documents supply further evidence, if any were needed, that the Justice Department authorised the CIA to torture prisoners in its custody," said Jameel Jaffer from the American Civil Liberties Union (ACLU). A memo released by the US Justice Department in 2002 told CIA interrogators that they would not violate the anti-torture laws unless they "have the specific intent to inflict severe pain or suffering" on terrorist suspects. "Because specific intent is an element of the offence, the absence of specific intent negates the charge of torture," said Jay Bybee, then assistant attorney-general, in the memo dated Aug.1, 2002. It also said that the interrogators would not be prosecuted if they believed in "good faith" the interrogation tactics did not cause prisoners a "prolonged mental harm." The 18-page memo was obtained by the ACLU through a Freedom of Information Act request and had been heavily redacted with only a few paragraphs left on eight pages. The other two memos were the CIA's request for legal advice on interrogation techniques.   A 2003 memo, signed by then-CIA Director George Tenet, instructed interrogators to record the sessions where "enhanced interrogation techniques" were employed. A 2004 memo said the employment of "water boarding", a form of simulated drowning, would not be considered a violation of anti-torture laws. The Bush administration's authorisation of harsh interrogation techniques on terror suspects was made public in 2004 when the Iraqi Abu Ghraib prison abuse scandal was revealed. However, the administration has consistently denied the US government has tortured any detainee. An unclassified memo released by the ACLU in April revealed that the Justice Department had authorised military interrogators to use harsh tactics on terrorist suspects. The 81-page memo, sent to the Pentagon on March 14, 2003, asserted that federal laws prohibiting assault, maiming and other crimes did not apply to military interrogators when they questioned Al-Qaeda captives because the president's ultimate authority as commander in chief overrode such statutes.
