There are methods, but all have flaws and risks, even this one.
A good method is to slowly release info on the more prominent actors, taking the time to discredit them first.
Some folks will never be outed as bad. So be it. Can't afford to make any martyrs, you know.
Look, it took a long time for things to get this way, going to take a long time to fix it, just not THAT long. Think for a minute. JFK assassination. Most of us know the "official" story is BS. We know this. We know the truth, for the most part, yet there is no "proof" of it generally had (unless you dig for it). But, we do know, even though we don't "officially" know. Some will be just like that. Word will leak, the truth will be "unofficial". Like it or not, that's just how it is.
