Theres plenty talk of this and thats in the going ons of the world, so much, it seems that secret societies and govermental coverups are everywhere.

Logically, you'd think theres people that would stuble across, leak info, defect, etc...Like talks of aliens and compaines secretly mutuating people for world takeover and top secret socieites or whatever. So what secret conspiracies have been blown wide open and exposed anyway?

Quite a few, I should think.

The first ones that come to mind are mostly medical, the government testing several diseases on soldiers, gonoreah, etc.

I'm sure many people here will be able to give specific examples.

Chappaquiddick - Suspended sentence for Kennedy who said he was not driving under the influence of alcohol.
Now common knowledge it was a cover up and that he had been drinking.

Several come to mind...

1. Watergate

2. DOD sanctioned bombing in Laos and Cambodia

3. McCarthy's HUAC campaign

4. Tuskeegee

5. Iran-Contra
