The Killing of America

Of course that if we watch it after "Bowling for Columbine", perhaps it will mean not much for you, but it definitely sets a horrible, sad and real background to all the violence phenomena that the USA has been living after 1963, and after a long journey through history, it ends up in the contemporary times of when the movie was made: 1982. The documentary is explicit, is depressive, sad, but still, very crude and accurate, and studying the theme from different points of view: anthropological, sociological, historical, etc. If you are interested in understanding how USA became so chaotic and yet the world potency, I think this movie is a must.
