Report on ECHELON Surveillance System (tags)
This is a 2001 document from the European Parliament, who undertook a relatively independent investigation of the ECHELON surveillance system — bizarrely, many people continue to dismiss this as a mere conspiracy theory. Then again, many people are Mormons. This report is solid gold for anyone looking to understand the precise mechanics and methodology behind global interception of electronic communication. It goes into a great amount of detail and will prove invaluable to serious researchers.
