"Meet The New Boss"
The Obama administration seems just as determined as the Bush administration was to making sure that nobody has any legal recourse if they’ve been subject to illegal surveillance. The process is getting pretty Kafkaesque here; the basic shape of things is that you can’t sue the government over secret illegal surveillance because since the surveillance happened in secret, you can’t prove it happened. And you can’t get the documents that might prove it happened, because that would compromise the secrecy.
Personally, I don’t see any way that could wind up leading to abuses.
