It's at www.witness.org. The idea is to have an international posting place where locals can video tape human rights violations around the world (yes, even at the hands of the US Gov't) and/or create documentaries on human rights abuses by primarily governmental agencies.
Some of the videos are free, some you have to pay for, but the bottom line is that it's pretty stunning how many of these videos are available.
Warning! Some of these are not for the faint of heart. In fact, if you have a heart, a soul, a conscience, or any type of feelings about humanity, some of these will...well...freak you out.
