I've read some accounts of one of Saddam Hussein's interrogators and they are pretty interesting, one of the things he did to establish a rapport with Saddam was to read his poetry. Apparently the poetry was atrocious but he was able to pretty decent rapport with him and glean a lot of info from the interrogations.
Bullshit. You don't have to read a book from one of the creators of program, and provide him royalties, in order to have a informed opinion on a pretty well covered program. You don't think the guy won't give the most favorable account possible to defend himself?
Everyone from SERE to General Mattis and countless cases of domestic police 'enhanced interrogation' with disastrous results have discounted the effectiveness the torture used in 'EIT'. Of course the guy is going to claim his methods worked, he is one of the primary ones response for developing them. But the greatest irony I see in the whole mess is he taught at the school where they teach that the methods they used aren't effective. And they aren't. Then there is the simple fact that it goes against our core values, not to mention laws, as a nation.
A much more comprehensive review and criticism of the author's work was published in the CIA's Studies in Intelligence, to include pointing out several false claims and glaring omissions the author makes in his book, it is lengthy but well worth the read.
