This is quite informative.

Amateurs trying to do a professional interrogation job would explain quite a bit. It would be very instructive to see what commonality there was between British R2I techniques and the U.S. "coercive techniques."

In the U.S., these procedures are listed under "RTI."

I think the bit about "Many of them still think they are dealing with people responsible for 9/11" is a bit of a cheap shot, and probably not true. Most of these soldiers have lost friends and comrades, sometimes in horrible ways, and I would venture to say that this alone would be enough to get "the gloves off."
