BTW, if you watch some of William Binney's talks, most notably the one he gave recently at 29C3, he talks about how the NSA gives *billions* of dollars in political kick backs to their favored contractors, and spend billions of dollars where they could have spent a few million (such as on his data analysis system). The NSA doesn't make the most efficient use of the resources that they have. They are a government agency after all, as inefficient as all the rest.
