In the early 1960s, Chan Thomas wrote a book titled The Adam and Eve Story and attempted to have it published by Emerson House in Los Angeles. Soon after publishing the full issue, the CIA classified his book for 50 years. An FOIA lawsuit was filed against the CIA to release the book. In 2013, the CIA released a "cleansed" version of the original book (50 pages out of 240 original pages).
Why was this book classified?

My departure from graduate school came with the knowledge that money runs everything.
