If you are in a position to know such a thing, and you assert its veracity, then I don't think I can properly say that I have "debunked" it without actually investigating your role and showing that your assertion is false.

There is a difference between a claim being unproven - and properly erring on the side of caution and skepticism - and claiming that the story has been investigated and debunked (when, to my knowledge, it has not).
