Part 4 of a new five-part documentary on the national security state, from the maker of Psywar. We do not necessarily agree with the accuracy of all of the material. But it is an enormously compelling and worthwhile watch. (All five parts of the documentary will appear on our site. See Part I here; Part 2 here; Part 3 here) NOTE: We previously posted the incorrect Part 4 video here. Now corrected.
