The Connecticut case [the library is sueing the FBI] affords a rare glimpse of an exponentially growing practice of domestic surveillance under the USA Patriot Act, which marked its fourth anniversary on Oct. 26. "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 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. In late 2003, the Bush administration reversed a long-standing policy requiring agents to destroy their files on innocent American citizens, companies and residents when investigations closed. Late last month, President Bush signed Executive Order 13388, expanding access to those files for "state, local and tribal" governments and for "appropriate private sector entities," which are not defined.
