If perpetrators come under suspicion, the media covers for them using a tactic called "psychological projection," where the guilty party shifts the blame by accusing the innocent party, thus discrediting those exposing the fraud.
Joseph Goebbels, a master at mass manipulation, stated of the Nazi deep-state:
"It is the absolute right of the state to supervise the formation of public opinion ... Think of the press as a great keyboard on which the government can play."
"If you tell a lie big enough and keep repeating it, people will eventually come to believe it ...
It thus becomes vitally important for the state to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the state."
False "experts" are interviewed by the media, as noted in Manufacturing Consent: The Political Economy of the Mass Media (1988) by Edward Herman and Noam Chomsky:
"The propaganda model also incorporates ... 'experts' to confirm the official slant on the news ... taken for granted by media personnel and the elite, but are often resisted by the general population."
