I guess you can debate the morality of developing weapons. I'd say that blowing up an Iranian nuclear bomb factory is a net positive. But that's irrelevant to my point, which was how great it would be to work on a cutting edge project with heaps of resources.
Anyway, yes, you can disappear even if you're citizen of USA: http://en.wikipedia.org/wiki/American_detainees_at_Guantanam...
and there are countries with even more lax standarts: http://en.wikipedia.org/wiki/Mordechai_Vanunu
Democracies go crazy when they get terror problems and throw out the law books -- see e.g. Germany, Italy, Israel, GB and USA. (I assume that is because voters get upset and votes out politicians that seems to be soft.)
Vanunu published maximum top secret information for a country with not only a terror problem, but an existential threat. Check Gerald Bull for what can happen -- or look what happened in Iran last year, when people complained about a stolen election and the Republican Guard felt threatened.
Edit: Fixed grammar/clarity a little. What I really wanted to say was -- I don't want a job like that. First, security is theoretically interesting but painful to work with in practice. Second, the bureaucracy will be horrible. State jobs without transparency are horribly inefficient and boring. Think bad tasting coffee, no flex, etc.
Edit 2: The nuclear capability was known, but not confirmed (still today, afaik). Also, if someone murders someone that is found out to have terminal cancer -- should they get a shorter punishment...? They must put pressure on Vanunu as a message to the next one talking too much; also game theory 101.
In fact there probably would have been less of a need for Stuxnet, were it not for Vanunu!
No, not that I know. Then again I don't know if the Russians, Israelis, Chinese or whoever wrote it make their engineers disappear, either (well maybe if they're also secretly plotting a revolt or something, I mean for working on these things).
The others are not people who worked on secret things and were detained/killed/whatever for that fact alone, to cover up that they developed that. That's what I was saying.
