"People talk and are eventually found out."

Yeah. But what if they talk to someone and almost no one listens? (meaning, the mainstream media and the *officially recognized* authorities on the matter give it no coverage, no recognition and no credence)

Well, then, it appears to the general public as if no one has talked, doesn't it?

That's the power of media coverage or the lack of it. That's the power of official recognition by authoritative bodies such as the Warren Commission...or not official recognition by such bodies.

That's how a coverup is done, if it is managed at a higher government level...simply by controlling the information that reaches the mainstream. It is not done by ensuring that no one talks (although that would be the ideal objective), it is done by ensuring that virtually no one listens to anyone who DOES talk...and virtually no one reports it...and the very few who do are dismissed as cranks and "conspiracy theorists"...and their careers suffer accordingly. They become outcasts in their chosen profession.
