You have to remember that Federal investigations don't work like that. They don't arrest (even if it appears obvious) and then build evidence; they build a strong case quietly then arrest (look up Prenda Law for a good story on this).
Interestingly though, most of the time public or powerful figures go to jail it's not (or not mainly) for the crime assumed, it's for 'Lying to the Feds' (see Martha Stewart for example). It's notoriously hard and time consuming to put away the big time criminals because they have big time resources and connections.
