The NSA turned down a ProPublica Freedom of Information Act request because it says it lacks the ability to search all the email within its internal network, so it can't answer a question like "What conversations took place between the NSA and National Geographic in the lead-up to a positive story about the Agency?" It can only search one user's mail at a time, not all 30,000 NSA employees.
"There's no central method to search an email at this time with the way our records are set up, unfortunately," NSA Freedom of Information Act officer Cindy Blacker told me last week.
The system is "a little antiquated and archaic," she added.
