That Matthew Alexander is the person that authored a really good read called, "How to break a terrorist"
. His name is a pseudonym.
What he details in his book is the "new methods", based on criminal investigation techniques, he used to interrogate the enemy. He and his team did not use the "old school" fear and control method. Rather they used their knowledge of Middle Eastern culture, the Koran, Middle Eastern history, and cunning to get captives to talk.
He talked about the culture of the "old school" interrogation adherents and what he was up-against with them. The old school guys, in most respects, have minimalized the enemy to neo-racial epithets (i.e., Muj, and Haji) and racial stereo-typing.
He indicated that he had no love for the enemy, but felt a better tactic to get them "to talk" was to win the captives over with cunning honest talk.
The reader gets a bit of cultural knowledge too. One prisoner is named "Abu Ali". Abu, we learn, means "father of", so Abu Ali means "father of Ali". It becomes key to breaking down one prisoner.
In the book, he mentions how he got a suicide bomb maker to talk by, of all things, getting into a discussion with the guy about the bomb maker's second wife.
