New study shows that Mafia accountants are really good at their jobs

A recent scientific paper out of Florida International University examined data from Italian criminal records to determine the quality of accountants affiliated with organized crime groups. As it turns out, Mafiosos tend to hire meticulous, careful, and detailed accounting firms to cook their books with their care and, perhaps more interestingly, that being associated with the mob has no negative impact on the accounting firms' reputations or non-mafia-related work (emphasis added):

While the work accountants do for organized crime group (OCG) ecosystem is not observable, we can determine if OCG hire "good" accountants by assessing the overall quality of their work as external monitors of legal businesses.
