NSA System That Detects Dissent Via Omnipresent Sensors Exposed (VIDEO)

The dystopian movie V for Vendetta features a scene in which goons working for the totalitarian government drive down residential streets with spy technology listening to people's conversations to detect the vehemence of criticism against the state.

Such technology already exists or is rapidly being introduced through a number of different guises in America and numerous other developed countries.

The Washington Post recently published a feature length article on gunshot detectors, known as ShotSpotter, which detailed how in Washington DC there are now, "at least 300 acoustic sensors across 20 square miles of the city," microphones wrapped in a weather-proof shell that can detect the location of a sound down to a few yards and analyze the audio using a computer program.

While the systems are touted as "gunshot detectors," as the New York Times reported in May 2012, similar technology is already installed in over 70 cities around the country, and in some cases it is being used to listen to conversations.
