According to this story from the Las Vegas Review-Journal, “Casinos have long reaped profits from what can politely be described as plausible deniability when it comes to identifying the source of their large cash customers’ income.” Jennifer Shasky Calvery, director of the Financial Crimes Enforcement Network (FinCEN), wants to put a stop to that. In a speech at the annual gambling trade show, G2E, Shaky Calvery called for a cultural change inside the casino business to root out and stop financial crimes, such as money laundering. This comes as an ominous warning for casinos, who often benefit from some shady deals.
