Book Review: Chatter: Dispatches from the Secret World of Global Eavesdropping

 I just finished reading Chatter by Patrick Radden Keefe.  Chatter is an in-depth look at the U.S. intelligence gathering system known as Echelon.  Patrick has done a remarkable job in gathering information and presentation of the facts regarding the secretive world of SigInt (Signal Intelligence), where the only official responses range from silence to denial.   The book also points out that Echelon isn't just a U.S. system, but more than likely an unacknowledged agreement between the U.S., Britain, Canada, and Australia, where listening outposts are manned by cross-government teams and information is shared between the members of the agreement.  The book is an excellent read.
