Stars take a stand against NSA snooping

Actress Maggie Gyllenhaal, actor John Cusack and director Oliver Stone have united to “sound the alarm over unconstitutional government surveillance” in a new video released Wednesday by the StopWatching.us coalition.

“We need to end mass suspicionless surveillance,” Gyllenhaal says in the video, which calls for a congressional investigation into the National Security Agency's surveillance programs.

“The tools for surveillance have never been more powerful,” Cusack adds. “And the threat to our civil liberties has never been greater.”

Rep. John Conyers (D-Mich.) also appears in the spot, along with a group of activists and legal figures. Click above to watch.
