It's funny 'cuz where I grew up Q-clearances grow on trees. Chinese, Iraqis, Slavs, didn't matter. G-men walking around asking old people questions on a daily basis and in the end, nobody could pin a thing on Wen Ho Lee. And the guys I know from military intelligence, who only had access to short-term, limited-value intel are hella more paranoid about saying the wrong thing than the guys I know from biowar who will just drop shit without a concern.
It goes to my point - back when we had actual adversaries with legitimate intelligence operations, things were pretty chillaxed. But now that we're jumping at shadows and wondering where the next Richard Reid is coming from, we've got academic advisors cautioning undergrads against badspeak.
