I knew a guy who lost his TS clearance back in the cold war days, apparently for the problem mentioned in section (b)(2) and maybe (b)(3) in your post. My belief is that he got trapped in a honeypot.
I feel sorry for him, because it pretty much destroyed his employability in his chosen field, but he should have known better than to get involved in something like that. I don’t believe he knowingly or maliciously divulged sensitive information, but he put himself in a situation in which that could certainly be suspected.
Brennan, and his associates, want us to think that the clearance is an entitlement and that security is a joke. Nothing could be further from the truth. And much worse, the talking heads in the MSM, and most liberals in general, have no clue whatsoever what is involved in security clearances, and the responsibilities that they entail (especially at the highest levels).
So, Comrade Brennan, I say “TS” to you (and by that I don’t mean “top secret”).
