Who is listening-in on your phone calls? Probably nobody. Right now, there is huge interest in phone tapping in the United States because the Bush Administration (through the National Security Agency) was caught listening in without appropriate court orders.

This article by Robert Cringley contains the basics surrounding phone taps and the history surrounding the legality of them.
