Yes, yes, we know it’s criminal.
Let’s get on with the prosecutions and incarcerations, shall we?
Vetted patriots in the intel community need to narrow down the possible leaking organizations (divisions or branches) and then announce lie detector tests for those organizations. They all have TS/SCI clearances so they are able to tested at anytime. Then just watch who quickly retires, etc.
BTW, these kind of tests are actually kind of rare, most TS/SCI cleared may get only one their entire careers, at least in the DoD, intel people may get more. (The tests are very time consuming, one investigator could do only 2 per day.)
