"We don't know if any of those with contacts to Al Qaeda, developed through the surveillance of foreign targets, are U.S. Citizens, no one has actually said that any were, AFAIK. I doubt if any of the critics actually know one way or the other."
That is an excellent point. But it certainly sounded to me from the president's and Alberto Gonzales' statement that we are talking about U.S. citizens. I hope that you are right and that the president will say that no citizens were targets.
Personally I don't care if they were or not. As long as they were ID'd via contacts with known terrorists overseas, surveiling them falls under the President's power as Commander in Chief and under the power delegated to him by Congress in their Authorization for use of force in the War on Terror. We are fighting a war here, not chasing common criminals, or even seditionists. They are trying to kill as many of us as they can. The job of the CinC is be prevent that.
IOW, I think some aspects of the FISA act are unconstitutional encroachments on the power delegated to the President by the Constitution.
