'SELF-POLICING'

According to the officials and a court document which the administration released, the NSA decided to "purge" the material after discovering it was inadvertently collected.

"When you look at these documents taken as a whole, you'll get a sense for the really effective self-policing that goes on at NSA," an intelligence official said. "Any time you have a large technologically complex operation that involves thousands of people, there will mistakes, there will be errors."

The historically ultra-secretive NSA has recently taken rare steps to openly discuss classified surveillance programs after the Snowden disclosures put the Obama administration on the spot to try and explain that U.S. intelligence agencies were not deliberately spying on Americans and foreign allies.

A handful of lawmakers, most notably Senator Ron Wyden, a Democratic member of the Senate Intelligence Committee, had begun complaining months ago that the NSA was eavesdropping on Americans' communications in ways that were excessive and not transparent.

Wyden, in a statement, said the declassification of the court ruling was "long overdue" and made clear that the law as written was "insufficient to adequately protect the civil liberties and privacy rights of law-abiding Americans and should be reformed."

Intelligence officials and the declassified documents explained that one of the main reasons that the NSA inadvertently collected information on Americans without proper legal authorization was that the method used to collect emails from targeted addresses linked to foreign suspects sometimes automatically brought into the agency batches of unrelated, and purely domestic, emails. Those should not have been collected without a warrant.
