Note, too, how German authorities found out about the planned attack. They eavesdropped on a phone call from Pakistan to Germany. This is the exact equivalent of the NSA program that is ritually, but inaccurately, described in the press as "domestic spying." Most Democrats denounce the program as unconstitutional.

Listening in on on calls from outside the US involving suspected terrorists is not a threat to my personal privacy. The politicians need to push for oversight and controls but stop demonizing the program.
