the point of this "Science of Interrogation" is exactly that-- using existing scientific research to improve how to interrogate detainees (i.e., no torture). You'd be surprised how little they know about the topic-- they've mostly been winging it.
I met with two very nice and non-tortuous ladies from the FBI who were quite interested in our research on question-asking. They wanted to know, among other things, what type of question gets a certain type of response.
And as to your question about MA in interrogation, the FBI does have a post-doc position available to research the subject. I was encouraged to apply, but I declined, for personal reasons. But it's all above board.
