Surveillance Court Judge Criticized NSA 'Overcollection' of Data

Newly declassified court documents show one of the National Security Agency's key surveillance programs was plagued by years of "systemic overcollection'' of private Internet communications.

A 117-page decision by Judge John Bates of the Foreign Intelligence Surveillance Court offers a scathing assessment of the NSA's ability to manage its own top-secret electronic surveillance of Internet metadata -- a program the NSA scrapped after a 2011 review found it wasn't fulfilling its mission.

The newly declassified documents suggest another possible reason for its demise. The surveillance agency struggled to collect metadata, such as the "to'' and "from'' information of an email, without also collecting other information, such as the contents or partial contents of such communications, information that is supposed to be beyond what it legally is permitted to gather.
