Court: Homeland Security must disclose cellular shutdown protocols

The US Department of Homeland Security’s ability to seek a shutdown of cellular and wireless networks in times of crisis, such as the potential of a remote detonation bomb threat isn’t new. Exactly how and when that authority can be used, however, must be disclosed, thanks to a new ruling by a Washington, D.C.-based court.

The US District Court for the District of Columbia has rejected Homeland Security’s argument that its reasoning and protocols for the so-called “kill switch” were exempt from public disclosure.
