I was given a great book last year for my birthday called "Torture Team" by Phillipe Sands. It's a fascinating look at a systemized government torture policy, chilling in it's detail and in the matter of fact nature of the people involved. Reminded me of reading about the Nazi's, amazing. There's an interview with Phillipe Sands on Fresh Air. Check it out!
Go to programs and check out Fresh Air. The program aired on Wednesday April 29 so look it up and listen to the interviews.
