"9500 Liberty" is the name of a documentary dealing with the immigration issue in Prince William County, Virginia. It was presented as balanced, but it was actually far-left, supportive of illegal immigration, and biased against white people. For instance, see youtube.com/watch?v=29WTKbpYhag where they present an older white gentleman in a bad light, footage that they repurposed at least one other time to make the same point; they wouldn't attempt to do the same with someone who's non-white (see if you can find anything like that on any of their dozens of videos).
They also promoted videos featuring Stephen Fuller of George Mason University promoting profiting from illegal immigration without disclosing that he was Chief Economist of a local bank.
Those involved are: Eric Byler, Annabel Park, and Jeff Man.
The first two are also leaders of the Coffee Party Movement, bringing the 9500Liberty magic to the opposition to the tea parties. The former will no doubt support massive/illegal immigration, an issue that the latter ignores; neither group represents the interests of the majority of Americans who want illegal immigration reduced.
