You won’t want to see this documentary film, but you need to.
This IMDB review sums it up well.
This is a very disturbing movie. Not because of the images — by now most educated persons probably know that 20th Century governments butchered 200 million or more people — but because of the blunt and matter-of-fact way it illustrates some of the precursors to genocide. Intellectually I understood the historical connection between authoritarian states, civilian disarmament, and genocide but now I understand it viscerally as well. From the first time I saw that roving gun sight until the final credits this documentary alternately horrified and enraged me. However, not everyone will finish this film feeling thoughtful. It does challenge some fundamental assumptions people make about genocide but I think that is a good thing. Pretty darned good for a movie with only a $90,000 budget.
