More abstractly, most everyone bends over backwards to promote their subconsciously estimated personal ~~illusion~~ model of reality as being representative of shared reality.
The US intelligence agencies don't themselves have a clean record: COINTELPRO, PRISM, CIA spying on the Senate intelligence committee (then lying about it).
Each of those counts as a conspiracy, and it's of note that people like Edward Snowden have been hunted and chased out of the country (and people like Julian Assange similarly persecuted).
