WASHINGTON – The National Security Agency for almost three years searched a massive database of Americans phone call records attempting to identify potential terrorists in violation of court-approved privacy rules.
The problem went unfixed because no one at the agency had a full technical understanding of how its system worked, according to new documents and senior government officials.
Moreover, it was Justice Department officials who discovered the problem and reported it to the court that oversees surveillance programs, the documents show, undermining assertions by the NSA that self-reporting is part of its culture.
The improper activity went on from May 2006 to January 2009, according to a March 2009 opinion by Judge Reggie Walton, who serves on the Foreign Intelligence Surveillance Court.
It was one of more than a dozen documents declassified and released Tuesday in response to lawsuits by civil liberties groups and at the direction of President Barack Obama in the wake of the June disclosure by former NSA contractor Edward Snowden of the massive phone records collection.
The documents released today are a testament to the governments strong commitment to detecting, correcting and reporting mistakes that occur in implementing technologically complex intelligence collection activities, and to continually improving its oversight and compliance processes, said James Clapper, the director of national intelligence.
The rebuke of the NSA comes less than a month after the Office of the Director of National Intelligence released a highly critical FISA court opinion that took the agency to task for its operation of a separate surveillance program.
Taken together, the documents paint a picture of an agency that has sweeping surveillance powers without full understanding of the efforts, and that has repeatedly misrepresented the programs scope to its court overseer. Such revelations call into question the effectiveness of an oversight program that depends on accurate disclosure by the NSA to a court that acts in secret and says it lacks the resources to verify independently the agencys assertions.
Privacy procedures have been so frequently and systemically violated that it can fairly be said that this critical element of the overall phone records regime has never fully functioned effectively, Walton said.
