The New Hows and Whys of Global Eavesdropping [book review: for access: "legion" "legion"] Remember chatter? After 9/11, it was all over the news. For months, snatches of cellphone conversations in Karachi or Tora Bora routinely made the front page. Television newscasters could chill the blood instantly by reporting on "increased levels of chatter" somewhere in the ether. But what exactly was it? Who was picking it up, and how were they making sense of it? Patrick Radden Keefe does his best to answer these questions and demystify a very mysterious subject in "Chatter," a beginner's guide to the world of electronic espionage and the work of the National Security Agency, responsible for communications security and signals intelligence, or "sigint." In a series of semiautonomous chapters, he describes Echelon, the vast electronic intelligence-gathering system operated by the United States and its English-speaking allies; surveys the current technology of global eavesdropping; and tries to sort out the vexed issue of privacy rights versus security demands in a world at war with terrorism.
