Re: Time on their hands
No need to be desperate. If you are even close to being part of the intelligence community, everything you do can be wrapped in secrecy (so you can get away with anything, or nothing) and if someone *does* call you out for being an oxygen thief then you can resort to plan B which is to accuse them of being un-patriotic, or working for the enemy, or soft on crime, or ... well, it hardly matters because everything you might use to judge the accuracy of the accusation turns out to be secret. ("Trust us, our anti-terrorism squads have saved thousands. No, we can't tell you any more than that, just thousands.")
Keeping secrets has two costs. There's the explicit cost of whatever infrastructure you use to guard your secrets, and then there's the hidden cost of all the incompetence and waste that is never addressed. I suspect that the latter usually outweighs the former, which is why secrecy is something that a state should minimise.
