Here’s an interesting little interactive space to explore the details on the use of torture by the US government: What is torture? – An interactive primer on American interrogation.
It’s from Slate, which presumably will cause some to ignore it as biased. But I think they do a really good job of separating the facts from their commentary on the facts.
A discussion of the same information was apparently broadcast as a joint venture between NPR and Slate, and is available for listening via Realmedia at Slate’s Jurisprudence: Torture and ‘War on Terror’.
