Citizen Four DVD

Citizen Four | | Instant Video

Citizen Four is an academy-award winning documentary about former NSA contractor Edward Snowden, who in 2013 leaked classified information which led to revelations of global surveillance by the NSA, GCHQ, and other intelligence agencies. The documentary primarily features interviews conducted with Snowden in a Hong Kong hotel room by journalists Laura Poitras , Glenn Greenwald, and Ewen MacAskill. These are interpersed with archive footage of press revelations and government responses.

The documentary focuses primarily on the moral and philosophical implications of a surveillance state which, although quite abstract, can make for great classroom viewing material for ITGS students. The documentary works well when tied in with the myriad news articles that have been written on the subject and a discussion of how technical capabilities can often develop quicker than legalisation and understanding of their social implications.
