I operated krypto gear in the USASA in the 70's. That required a top secret security clearance. I don't care if I liked what I heard while in a communication center in Germany or not, I would never break the oath. Not even today. To say he is anything but a criminal is to say that if you think you're right, even if it is against the law and you break that law, then, hey, maybe you're a hero.

He knew it was wrong, or he would have stayed around to face the consequences. I think he is in deep trouble.
