Isn't this one of those situations where anyone who will tell you is probably a source you shouldn't consider reliable, and anyone who actually could tell you...really actually can't tell you?
In a way, yes. Obviously, there are a lot of things that have been declassified by now, as the founding of the CIA may not be sensitive information these days.
But I have the same reaction when I hear anything from intelligence organizations or certain special ops units. In a lot of cases they can't tell the truth and sometimes they actually have to lie. So why would I believe them?
