Heres the kicker:

Even if upon examination a communication is found to be domestic – entirely within the US – the NSA can appeal to its director to keep what it has found if it contains “significant foreign intelligence information”, “evidence of a crime”, “technical data base information” (such as encrypted communications), or “information pertaining to a threat of serious harm to life or property”

Or James Rosen...or AP...or.

Logic tells you that since they can't listen to EVERY call in real-time, then EVERY call is recorded.

Every phone call in the US is recorded and "electronically" vacuumed for keywords.

Shortened... EVERY PHONE CALL BY CITIZENS IN THE UNITED STATES IS RECORDED.
