The Washtington Post has a very long and equally interesting article on "national security letters", a new tool given to the FBI under the USA Patriot Act. Their use is growing quickly and, as importantly, the FBI is putting all information gleaned by this mechanism into large databases. Thanks to Daniel Solove at Concurring Opinions for pointing to this article:

The FBI's Secret Scrutiny

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. 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.

National security letters offer a case study of the impact of the Patriot Act outside the spotlight of political debate. Drafted in haste after the Sept. 11, 2001, attacks, the law's 132 pages wrought scores of changes in the landscape of intelligence and law enforcement. Many received far more attention than the amendments to a seemingly pedestrian power to review "transactional records." But few if any other provisions touch as many ordinary Americans without their knowledge.

Senior FBI officials acknowledged in interviews that the proliferation of national security letters results primarily from the bureau's new authority to collect intimate facts about people who are not suspected of any wrongdoing. Criticized for failure to detect the Sept. 11 plot, the bureau now casts a much wider net, using national security letters to generate leads as well as to pursue them. Casual or unwitting contact with a suspect -- a single telephone call, for example -- may attract the attention of investigators and subject a person to scrutiny about which he never learns.
