Rise in FBI use of national security letters

WASHINGTON -- The number of people the FBI targeted with national security letters more than doubled last year to more than 14,000.

The letters enable the bureau to collect a large amount of sensitive information like financial and phone records in terrorism and espionage investigations. In 2007, the Justice Department's inspector general found widespread violations in FBI use of the letters, including demands without proper authorization and information obtained in non-emergency circumstances. The FBI has tightened oversight of the system. The letters are controversial because there is no court scrutiny of the process.

In a summary to Congress, the Justice Department said the FBI made 24,287 national security letter requests last year for information regarding 14,212 people. That's up from 2009 when there were 14,788 requests for information about 6,114 people.
