Claude Foulk, Hospital Director, Accused of Raping Children Since 1975

“The NSA (National Security Agency) is sort of two organizations in one; the director of NSA wears two hats. If you ever get a letter from NSA or whatever, it says—the letterhead says, “National Security Agency/Central Security Service.” And the director always signs his name “Director NSA/Chief CSS.”
The National Security Agency is largely civilians, and they’re mostly the analysts and the people who design the sophisticated satellites and do a lot of the technical development work and break a lot of the codes and so forth. And the people on the front lines, the intercept operators, are almost all military, and some civilians who transition from the military into a private contractor, for example. So, most of those are the military, but they all come under the same organization. The military is technically the Central Security Service, which reports to the director of NSA, and the civilians are largely NSA analysts.”
