I think you could consider "government secrets" to be a test for government supremacism. If you justify government keeping anything secret, you have some government supremacism in you somewhere.
L. Neil Smith had said that government secrets should be the only capital crime. Of course, since government is the entity that carries out capital punishment (killing in defense isn't capital punishment), that would never work. Nor do I believe capital punishment is anything other than murder in revenge.
Since I don't believe in the right or "authority" of government to do anything (kill people, keep secrets, exist, etc.), I'm not on board with that, but I do agree that government keeping secrets from its superiors (anyone you could think of) is an unforgivable wrong.
You and I have a right to privacy from government's prying eyes and probing fingers, but governments have no rights at all-- they can't.
You may point out that what I consider wrong isn't going to change the criminal gang's behavior one bit. True.
Government cares about my opinions exactly as much as I care about its opinions. Still, I think it's a useful observation to make so you know where someone stands-- if they'll stand with you when the chips are down or if they're likely to sell you out because government says so.
