Old news but interesting. The Pentagon censored the contents of this book, but not after 10,000 copies were printed. The Pentagon purchased and destroyed those but some advance copies survived. Those copies commanded a premium price on ebay. One of the redactions: the location of the Central Intelligence Agency’s training facility — Camp Peary, Va., a fact discoverable from Wikipedia.
