Knowing that some classified program exists is one thing. Knowing technical details, capabilities, missions, targeting, is a whole nother. One can read about such black programs from a number of sources, Bamford's Puzzle Palace is one. Sontag's Blind Man's Bluff is another. You can also learn about such things from books and newspaper articles about people who revealed secret information to the Soviet Union, Chris Boyce, Aldrich Ames, Robert Hanssen, and the Walker Family. In other words, nothing is truly secret if you know where to look and have a ability to piece together disparate facts to build up a more complete picture.

"Blind Man's Bluff" was a really impressive piece of work, I once talked about it with someone who was involved with the program and he was astounded at how much Sontag had managed to find out. There were things in the book that he didn't even know about, because they were compartmentalised and Sontag wasn't.
