Well, I'm starting to get the feeling that the administration wants people to know they are breaking the law. They think it'll make people take them seriously. They are "Tough On Terror". Bush seemed proud of his illegal wiretapping during a press conference I watched on CSPAN, and, judging by the responses from people here, he is playing to his base.
Unfortunately, it makes him a common criminal, but hey, what is more important? Upholding an oaths, or winning elections? They want people to assume they are willing to torture confessions out of people as if they were "Special Agent Jack Bauer" trying to find the warhead before it goes off. They would also prefer people didn't know that they were really more like the Keystone Kops when it came to preventing another terrorist attack (at least according to the 9/11 commissioner's 'report card'.)
