More often than not it's not a matter of whether there was a conspiracy or not, but of what the conspiracy consisted of, and who was involved in it. Pretty well always when the confidential records come out years later it is revealed that the story that the public were told about public events wasn't actually that close to the truth. That's a conspiracy.

Of course some theories about conspiracy are daft, but then the truth is often pretty daft.

I've got a macro-conspiracy theory - it's that somewhere there are government agencies dreaming up and propagating a whole mass of conspiracy theories about everything - the idea being that people get scepitical about such notions, and that makes it easier to get away with
covert activities. The Mudcat is just the kind of place they'd use to play games like that...
