I was an interrogator and analyst for the Defense Intelligence Agency in the late 60s and early 70s.  When I was in training the first thing they taught us was that torture was both illegal  and ineffective.  When you torture people they tell you what they think you want to hear not the truth.   As a former DIA operative I must admit I don’t have a lot of use for the CIA.  Many if not most of our recent international problems are blowback from CIA activities.  That would include the Vietnam war and our problems with Iran.  Perhaps this will shed some light:

Senate panel votes to release CIA interrogation report

The Senate Intelligence Committee voted Thursday to make public a long-awaited report that concludes that the CIA’s use of brutal interrogation measures did not produce valuable intelligence and that the agency repeatedly misled government officials about the severity and success of the program.

The decision, opposed by three Republicans on the panel, means that the findings will be sent to the White House and the CIA, putting the agency in the awkward position of having to declassify a document that delivers a scathing verdict on one of the most controversial periods in its history.

Don’t get me wrong. I think that most of the CIA operatives are good  Americans and good people.  But there are a minority who are not and the agency has been politicized over the years.  Torture is un=American and we executed Japanese for water boarding after WWII.
