I started this thread to get some discussion going. I'm not at all surprised that these things were happening, but kind of surprised the CIA admitted it and that it didn't get any results. I mean do what you need to do, but if it's not working, figure out a way that will.
Also, I saw this earlier today. Not necessarily related to interrogation tactics, but definitely related to hostage negotiation tactics. Don't mess with the Russians:
After trying peaceful negotiations:
"KGB agents ran the name of a prominent Hezbollah leader through their computers and came up with the name and address of one of his closest blood relatives. They then kidnapped the kinsman, castrated him, and sent his severed organs to the Hezbollah honcho.
The package was accompanied by a terse cover note indicating that the KGB had the names of other close relatives and that Hezbollah could expect more such deliveries unless the three remaining hostages were freed forthwith.
It didn't take much time for Hezbollah to realize it was dealing with a different breed of "Great Satan." The three surviving hostages were dropped off only 150 yards from the Soviet Embassy from a late-model BMW that couldn't drive away fast enough."
