The models that exist for how and why our government classifies a document as being "secret" are unknown to most Americans. To many in the intelligence community, the need for this system is essential to fight terrorism. But is this level of secrecy impeding national security or helping it? Secrecy, a powerful film by Robb Moss and Peter Galison, examines the complexities of our government's obsession with secrecy and its effects. Secrecy takes us into the dark shadows of this process, shedding light on the implications behind classifying a document as secret -- and also asking who polices the state's ability to do so.
