So far, this report from a left-leaning blog is unsubstantiated by a second source. If it's true, however, that the White House is using the Patriot Act and National Security Letters to gather information on people for no reason other than the fact that they're Bush's political enemies, then this administration truly has crossed the fine line between clueless and evil. I'll reserve judgment on this until I find another source - you're encouraged to help too.
This reminds me, however, of an excellent Post article about national security letters and their impact on the war on terror and our right to privacy. It's very balanced and well-written, but sadly, I can't get to the Post's site right now so I can't give you a link. Boo.
