In his review of "Chatter", by Patrick Radden Keefe, Mr. Saffire says "What to do about Echelon?" Quoting Keefe, he says '"We don't know whether Echelon exists"'. I call your attention to a 194 page report prepared by the European Parliament, entitled "Report on the existence of a global system for the interception of private and commercial communications (ECHELON interception system)". In addition, a Google search for "Echelon NSA" will turn up over 93,000 entries. The European Parliament report can be found at:
