The FBI illegally collected more than 2,000 U.S. telephone call records between 2002 and 2006 by invoking terrorism emergencies that did not exist or simply persuading phone companies to provide records, according to internal bureau memos and interviews. FBI officials issued approvals after the fact to justify their actions. E-mails obtained by The Washington Post detail how counterterrorism officials inside FBI headquarters did not follow their own procedures that were put in place to protect civil liberties. A Justice Department inspector general's report due out this month is expected to conclude that the FBI frequently violated the law with its emergency requests. FBI officials said they thought that nearly all of the requests involved terrorism investigations. FBI general counsel Valerie Caproni said ... that the FBI technically violated the Electronic Communications Privacy Act when agents invoked nonexistent emergencies to collect records.
