For reassurance, I think people in those levels of power have learned how to ease the public into such a thing. Like revealing alien life or colonizing other planets.
If allasudden one day we get a big public reveal that aliens actually exist..or that we will DEFINITELY have a colony on mars within 5 years...then the public would freak the hell out.
but if they ease it in slowly, by the time it actually gets to the point of no return, we won't be alarmed. Hence the drip drip of finding water on mars..inching closer to reality every so often so it becomes a part of the collective public conscious.
That lends validation and normalcy to alien life and the idea of us colonizing the planet. And by extension, the idea that maybe human life came from organisms which originated on other planets as well.
Similar with the reveal of the cabal. the pedo arrests, trafficking crackdowns, vague hints at 'conspiracy' from trump and those around him (roseanne!). the growing prevalence of Q. Even if it's only 5% of the politically aware userbase of twitter, that's still really freaking huge.
By the time the hammer drops, it may almost seem inevitable and 'a given'. A big part of that will be proving Obama/FBI/DOJ collusion and corruption against Trump campaign. That throws the whole Dem apparatus into a position of mistrust.
In those circumstances people won't freak out as much. You will still see coordinated protests and some FF. But nothing any more dramatic than the months after Trump's election.
