A good article on how Data Mining fails to catch terrorists. It doesn't go into great detail on the logical failings, which are often discussed at Schneier's blog, who linked the article and was quoted in it. This guy is great reading for someone who is concerned about privacy issues and security, which are big political topics right now. It's nice to see someone who opposes a program for good verifiable reasons, not political manuvering. When I'm President, I want him on my cabinet.
