SAN FRANCISCO (Reuters) - The National Security Agency routinely violated court-ordered privacy protections between 2006 and 2009 by examining phone numbers without sufficient intelligence tying them to associates of suspected terrorists, according to U.S. officials and documents that were declassified on Tuesday.
The Foreign Intelligence Surveillance Court, which oversees requests by spy agencies to tap phones and capture email in pursuit of information about foreign targets, required the NSA to have a "reasonable articulable suspicion" that phone numbers were connected to suspected terrorists before agents could search a massive call database to see what other numbers they had connected to, how often and for how long.
