In the race among U.S. law enforcement agencies to be the snoopiest, most intrusive, and greatest threat to privacy, it's really hard to score the players. To a great extent, that's because the eavesdroppers and keyhole-peepers are more enthusiastic about monitoring us than they are about letting us know that they're watching. Fortunately, the Electronic Frontier Foundation (EFF) is there to keep an eye on things and to let us know who is the nosiest of them all.
