Person X committed crime Y.
Prime minister blah is having an affair with bleh.
There is a secret base at location T studying V.
Most pieces of juicy information aren’t like secret scientific studies for anti gravity machines. They are just mundane things with excitement because of who is doing them and who it’s happening to.
Information is always that complex. "Intelligence" is a bunch of rumors and innuendo that get mushed together into an analyst's report.
Even when you have what you believe to be incontrovertible evidence, because this is spy shit you have the possibility of a foreign intelligence service finding your hidden camera and using it to feed you whatever they like. And the fewer eyes you have on it, the less likely you are to discover the inconsistency with reality.
Do you know, or does it just appear that way to the best of your knowledge. The black/blue, or white/gold, dress is a good example of seeing something doesn’t make it true, or false.
The much bigger, much more critical, secret is knowing someone did something because you, or more likely someone under your direct command, was involved in the action. In which case the secret is the culpability more than the action itself.
Naturally human nature is to think the opposite, that the most highly protected secrets have been carefully evaluated because they're so important, when the relationship is actually the inverse.
Maybe there should be a maximum period of time that any given information can remain classified, and maybe it should be short.
