Indeed, it had plenty, said the committee's report released Tuesday: about 50 years' worth. Deep in the committee's 500-page summary of a still-classified 6,700-page report on the agency's use of "enhanced interrogation techniques" after 9/11 there is a brief reference to KUBARK, the code name for a 1963 instruction manual on interrogation, which was used on subjects ranging from suspected Soviet double agents to Latin American dissidents and guerrillas.

The techniques will sound familiar to anybody who has followed the raging debate over interrogation techniques adopted by the CIA to break Al-Qaeda suspects in secret prisons around the world. When the going got tough, the CIA got rough.

The 1963 KUBARK manual included the "principal coercive techniques of interrogation: arrest, detention, deprivation of sensory stimuli through solitary confinement or similar methods, threats and fear, debility, pain, heightened suggestibility and hypnosis, narcosis and induced regression," the committee wrote.
