The events sited above are conspiracies which came to light by following proper investigative techniques - previously described. They did not start out as CT's that were later validated by people using proper investigative techniques.
You are incorrect. I tried to limit the list to things where there was public discussion, whistle blowing or journalistic exposure of events that were denied by those responsible, and later proven to be true.
CTs are not restricted to accusations against govt that are false. CTS are accusations against agencies (govt, corporate, individual) that are denied and/or covered up.
The govt puts flouride in our water to mind control us is a CT.
The catholic church moved priests accused of paedophilia to different areas where the accusations were not known is a CT that was proven true.
Both were vigorously denied when first raised.
