What is Biscuit?

I first read about biscuit inthis Molly Ivins article about the torture thing. Oh, I'm sorry, the alleged 'abuse' thing:

The creepiest aspect of the Red Cross report is the involvement of doctors and psychiatrists in something called "biscuit" teams. Get used to that acronym: It stands for Behavioral Science Consultation Team and will end up in the same category of national shame as Wounded Knee. According to The New York Times, "biscuit" teams are "composed of psychologists and psychological workers who advise the interrogators." Shades of Dr. Mengele.
