It is the trust people have in authority, and the normalcy biases that bound that trust, that allow for the brainwashing techniques to retain their hold. We are told from infancy to trust authority. The PTB have exploited that basic training to maximum advantage. It is a fundamental element in their spells.

It is only if the trust is broken, in even the slightest way, and normalcy bias is proven wrong on any level, that the door opens up to a deeper inquiry into reality.

This is almost certainly what "first indictment [unseal] will trigger mass pop awakening" means. It will shake both shake the trust in authority, and show that our normalcy biases do not stand the test of reality.
