"National security letters," created in the 1970s for espionage and terrorism investigations, originated as narrow exceptions in consumer privacy law, enabling the FBI to review in secret the customer records of suspected foreign agents. The Patriot Act, and Bush administration guidelines for its use, transformed those letters by permitting clandestine scrutiny of U.S. residents and visitors who are not alleged to be terrorists or spies.The FBI's Secret Scrutiny: In Hunt for Terrorists, Bureau Examines Records of Ordinary Americans (Washington Post)
The FBI now issues more than 30,000 national security letters a year, according to government sources, a hundredfold increase over historic norms. The letters -- one of which can be used to sweep up the records of many people -- are extending the bureau's reach as never before into the telephone calls, correspondence and financial lives of ordinary Americans.
Issued by FBI field supervisors, national security letters do not need the imprimatur of a prosecutor, grand jury or judge. They receive no review after the fact by the Justice Department or Congress. The executive branch maintains only statistics, which are incomplete and confined to classified reports. The Bush administration defeated legislation and a lawsuit to require a public accounting, and has offered no example in which the use of a national security letter helped disrupt a terrorist plot.
The burgeoning use of national security letters coincides with an unannounced decision to deposit all the information they yield into government data banks -- and to share those private records widely, in the federal government and beyond.
