How should we rank order the following in terms of their importance in how we want our government to behave: morally; legally, constitutionally, effectively? Of course, we want all these things, but when push comes to shove, as it does for an individual government worker in the CIA, a government agency, and a nation, what matters most?
Intriguingly, people don't lie and cheat indiscriminately -- simply because they can get away with it. Even when there is no chance of being found out, people show some level of aversion to acting unethically. They want it both ways: to profit by dishonesty, but also to preserve some sense of themselves as moral beings.
