Suspecting that people who complained about Saville were being sidelined and evidence hidden isn't suspecting about an individual. And there does seem to be something odd about the disappearance of Geoffrey Dicken's papers about high level child abuse, and the report data which was disappeared in Rotherham.

Which isn't what I was going to post.

Which was: setting up the concept of completely nutty, tinfoil helmeted, conspiracy theorists could be a very effective smokescreen to hide the real things. It is quite clear that throughout history there have been conspiracies, often combined with cockups, but not always.

With the Manhattan project, the context made keeping it secret much more likely than it would be in the cases of the Moon flights, which similarly involved very many people (one of whom I know).
