> Assuming that you are absolutely certain that it is indeed a fraud

There's the rub, right there. There will always be a tiny doubt. Especially as a worker bee who doesn't have all the inside facts. People tend to talk themselves out of taking action due to this. The resolution is to document what you know, incontrovertibly, leave all speculation out of it and then hand the problem over to someone else. Which is why tiplines exist at the SEC, DHS, and other agencies where this sort of self-doubt is a serious impediment to reporting of malfeasance.
