If you see something, film something. Capturing natural behavior of idiots in the position of power when they don’t think anybody is filming can be rather revealing.
This video was filmed in San Diego, California. Two US border patrol agents are seen holding a non violent man pinned to the ground while one of them beats him as he pleases. The man was reportedly a captured Mexican illegal (I suppose that’s what “indocumentado” means in Spanish) who managed to somehow sneak across the border into the United States.
