Lots of people who have never held a clearance don't seem to understand why state secrets exist, and why they're often a deadly serious matter. If intelligence sources and methods get revealed, that can sometimes result in someone ending up in the basement of a prison in some tinpot dictatorship with a pistol round in the back of their head. Or otherwise being literally taken out back and shot.

Some people's only frame of reference is that there's nothing "secret" that's of more import than that spreadsheet Katie from HR left out on her desk, and now OMG, everyone knows what everyone else makes, the horror . . .
