"Aboard the Wright, Woodward had top secret "crypto" clearance-the same clearance researcher Harold Weisberg found had been assigned to Lee Harvey Oswald when he was himself in the Marines. Such clearance in Woodward's case gave him full access to nearly all classified materials and codes on the ship. Woodward also ran the ship's newspaper. Woodward has insisted that possessing a high security clearance is not necessarily indicative of intelligence work."
He had access, he had the most sensitive clearance, he knew some of the most powerful people.... "
Having a "crypto clearance" means that you are allowed to type up messages that were decrypted. It's not a "most sensitive clearance" by any means.
Probably a hundred thousand guys and gals have had such clearance in the military. Including Oswald, who the KGB laughed at when he tried to sell them on his value as a defector.
Woodward was not a spy. He did not work in intelligence. That is all fantasy.
"Having a "crypto clearance" means that you are allowed to type up messages that were decrypted. It's not a "most sensitive clearance" by any means."
Wrong! It means you have access to an area where crypto equipment is used and possibly to an area where the crypto keys are kept. It doesn't get much higher than that, unless you are assigned to the PSA (Presidential Security Agency).
You really need to go school on Clearances.
