There's a much easier point to be made: If (i) Wikipedia doesn't mention it, and (ii) it's important enough that it would be reasonable to expect Wikipedia to mention it if there were evidence, then you should at least provide a citation as to why you believe such a thing. Otherwise, why should your readers accept your unsubstantiated hypothesis?

The typical line of thinking with conspiracy theories seems to be the less substantiated the theory, the more credence it should be lent, under the logic that the government is suppressing evidence.
So basically the less evidence, the more believable. Beautiful, isn't it?
