There is a bit of a difference - we have an abundance of evidence disproving the fake moon landing stories. OTOH, there were no witnesses of Kelly's death, and the timing was so very convenient - frankly, it's naive to think our security services wouldn't do this, especially with what was at stake. Keep in mind the the US and UK were fabricating evidence as justification for an illegal war. One that they knew would claim many, many casualties, and for which they must have known would end up destabilising the whole region and growing fundamentalists and terrorists (this was certainly obvious to many at the time).

I do see your point, mind, but I don't think such damning circumstantial evidence is "shit"; by that logic, MI6 could never be responsible for anything, unless of course they signed a confession.
