Aren’t the DC area offices of NSA and CIA for analysts, not for the spies who are supposedly out there spying?
NSA Headquarters is at Fort Meade in Maryland. Huge
complex there; large number of big satellite dishes,
big office buildings, armed guards, tall fences, etc.
They have other offices nearby in Jessup, MD at
Annapolis Junction and near BWI airport. Lots companies
that have contracts with NSA also have large fenced off
office buildings nearby in Annapolis Junction.
But I'm sure NSA has an office or two, or three,
or four in DC.
