Throwing it at the wall and see what sticks is always kinda stressful, eh? Most people throw and then run, when it comes down to it. Putting your name on the brick makes for interesting times.
Once in a while, there's someone with power who knows there's something wrong, but nobody without power is willing to talk.
It's the whole basis of military/authoritarian pomp and circumstance, as well as the huge overclassification of documents: keeping the naked truth away from those with power to do something.
Meanwhile, we also have to work at not giving them so much power to keep the walls up in the first place.
Money money money money money.
