A privacy rights group has brought a lawsuit to gain more detailed information on the federal government’s ability to shut off the internet in the event of a national crisis.

The Electronic Privacy Information Center (EPIC) has filed Freedom of Information Act lawsuit against the Department of Homeland Security, in response to a failure by the agency to release any documents pertaining to the “Emergency Wireless Protocols,” (Standard Operating Procedure 303 or “SOP 303″).

SOP 303 outlines exactly how the DHS would carry out a complete communications shutdown in the event of what it deemed an emergency situation.
