Jog, I have absolutely no way to discern the real truth, none.
Whatever it is has/had a lot of power.
The magnitude of cooperation it takes to keep the findings under wraps exhibits just how darning it must be.
What could possibly hold such sway?
All the speculation of a foreign government being involved would not rise to that threshold.
Nor would a rogue faction in any one department garner that much protection this late in the game.
Now in the other hand if it was a concerted effort by multiple departments, orchestrated from say, a LBJ, then it would have the capacity to shake our system of governance to it very foundation.
Our world standing, our financial standing, not to mention the attack of competing political system, how they would use this as a example as to why democracies won't work, as they bolster their own grip on their domains.
Would it not be hard for us then to preach about the tyrannies and dictators, as evil....yes?
I don't know Jog.
Far better minds than mine have wrestled with the possibilities, and all we have to show for it is a best guess scenario.
You take a stab at it, you might even hit a two-fer.....
