When your livelihood is based entirely on your security clearance and your ability to keep working in the security industry you make it a very big point to not talk about this stuff outside of work. I had a friend who went to work for a 3-letter agency and started consistently avoiding bars/drinking because he was afraid he'd say something. This is exactly why whistleblowing is a problem in the intelligence community - they'll sue you to oblivion and/or imprison you for saying anything at all.
