Allegedly. The CIA has negative credibility in this matter - what they say is less likely because they say it.count said:Not true. The CIA has obtained useful information that has broken up plots through the waterboarding of select individuals.
Dozens - probably hundreds - of people were tortured at Abu Ghraib and Gitmo: at Gitmo, at least, the CIA was involved. "Select individuals" my ass.
Besides: How much info have they destroyed, and how much have they lost in prevented opportunity for info, and how much info gathering time and expertise have they wasted chasing the kinds of garbage they claim to have obtained as "info" ? A good accounting includes the costs, not just the benefits.
The comparison is not with no info gathered, but with info gathered using better and more effective and less self-destructive means. And after that, the effects on a society of setting up its government with a clandestine torture agency can be tossed unto the scales.
The CIA was never very good at interrogation, it was never their area of training or expertise, and torturing has not improved their batting average if the crap they've proudly released is representative.
