Meet Russell Tice
...I'm involved with some certain aspects of the intelligence community, which are very closely held, and I believe I have seen some things that are illegal. Ultimately it's Congress's responsibility to conduct oversight in these things. I don't see it happening.[snip]
Well, as far as an intelligence officer, especially a SIGINT officer at N.S.A., we're taught from very early on in our careers that you just do not do this. This is probably the number one commandment of the SIGINT Ten Commandments as a SIGINT officer. You will not spy on Americans. It is drilled into our head over and over and over again in security briefings, at least twice a year, where you ultimately have to sign a paper that says you have gotten the briefing. Everyone at N.S.A. who’s a SIGINT officer knows that you do not do this. Ultimately, so do the leaders of N.S.A., and apparently the leaders of N.S.A. have decided that they were just going to go against the tenets of something that’s a gospel to a SIGINT officer.[snip]
Well, I think this investigating [the Justice Department's pursuit of whoever leaked the story of Bush's spy program] is an attempt to make sure that no intelligence officer ever considers doing this. What was done to me was basically an attempt to tell other intelligence officers, ‘Hey, if you do something like this, if you do something to tick us off, we're going to take your job from you, we're gonna do some unpleasant things to you.’
So, right now, the atmosphere at N.S.A. and D.I.A., for that matter, is fear. The security services basically rule over the employees with fear, and people are afraid to come forward. People know if they come forward even in the legal means, like coming to Congress with a concern, your career is over. And that's just the best scenario. There’s all sorts of other unfortunate things like, perhaps, if someone gets thrown in jail for either a witch-hunt or something trumping up charges or, you know, this guy who is basically reporting a crime.
