Oversight board urges national security agencies to update surveillance guidelines

An independent oversight board reviewing secret government surveillance programs is warning that national security agencies' rules governing surveillance are outdated and need to be revised to reflect rapid advances in technology.

David Medine, chairman of the Privacy and Civil Liberties Board, wrote to Attorney General Eric Holder and Director of National Intelligence James Clapper, urging that rules governing collection and retention of data about U.S. citizens be updated to "appropriately capture both the evolution of technology and the roles and capabilities of the intelligence community since 9/11."

The rules were established by a Reagan-era presidential executive order that still governs much of the nation's intelligence collections.

Medine said Friday that the National Security Agency, which oversees most surveillance programs, has not updated its guidelines since 1993.
