I suspect that this is simply a way to revoke Pre-Check status for that small number of people who simply refuse to understand how Pre-Check works, consistently violate the obvious rules about prohibited items at the checkpoint, pull the DYKWIA card once too often, and so on. And, obviously, there needs to be a way to note that the status shouldn't be granted again if the passenger re-applies.

That's the optimistic way of looking at it.

The pessimistic way of looking at it, of course, is that this is a way for rogue TSOs to arbitrarily punish passengers for disrespecting their authority, flying while non-Anglo, etc..

Of course, TSA's lack of transparency means that either possibility could be true, and we have no way of knowing ...
