Exactly. I have friends and family who have or have had various high clearances who are extremely cautious about even alluding to work they did decades ago. The idea of publicly proclaiming how one obtained that kind of intel while working for the DIA seems more than a bit odd. Of course, Patrick Lang does seem to be quite a loose cannon.
The higher the IQ the better the chance of craziness and no one gets into military intelligence without a high IQ.
