Well, that just goes to show that Mob guys aren't the only people stupid enough to get caught in tax raps. It's easy for the government to bring a tax case to trial: they don't have to show how you made the money, only that you are or were living above your means. And don't expect any sympathy from a jury--the prosecutor will make the point that the reason they are paying high taxes is because people like you are cheating on yours.
