LOL, I though one would need to do a FOIA request or something to do that.
My situation never went anywhere. I had made a complaint regarding a government contractor that I had worked for.
The company unleashed the dogs on me and I dropped it. It cost me bigtime and I will never forgive them. But I have moved on, as they say. The company is no longer. I still have a story to tell, but nobody would be interested now, except for maybe the EPA.
I no longer even reside in the state, so frankly, I don't care.
That's one way. Another is to have an uncle who retired as a fairly senior federal LEO, and kept some material for his personal protection, much the way Director Hoover did. After following the boss's example is the path to attaboys and promotion, right.
Long ago when I asked him about such things, he counseled me against following in his foosteps; even his own agency had more than its share of incompetence, corruption and coverup, and had sunk to a standard lower than he had always held himself. By way of a present and legacy, after his death I got some of the material he'd kept. More I got by horsetrading information related to what I was interested in. And there were others in state and local law enforcement who hadc a pretty good idea of what had happened.
