I understand. Different people have different thresholds for trust. Unfortunately, I have lived in DC for a long time. Long enough to know the basics of how espionage works. And, appealing to authority is very effective. Humans love authorities. Write a few papers. Give a few conference talks. Get a few magazines to report on your expertise. That's pretty much all it takes to get entry. Otto and Olaf are probably great guys. I'm just extra cautious.
