Slowyly by slowly the pit starts cracking and slowly by slowly the crack travels across the windshield. Once pitted and it starts traveling you can't stop it.
A dam* cracks. Tiny at first. But then it spreads and you can't stop it or repair it. Eventually it breaks wide open and whatever is in is path is wiped out.
One person tells the truth and a government is pitted. Then another and another and another and another until the gubment breaks wide open. Once started it cannot be stopped until all have spoken.
Moral? Listen for the PING. Once you hear it get out. Resign. Leave. The end is coming and you'd better get out of the way or you will be Tsunamied.
