Online gambling might be coming to a computer near you, and while it may seem like the only risk is on the player, the FBI fears it will be used by terrorists and organized crime rings to launder money.

In a September 2013 letter to Congress, the FBI warned that while many industries are vulnerable to money laundering, Internet gambling goes a step further by providing an anonymous forum for bad actors to move money undetected: “Online gambling, therefore, may provide more opportunities for criminals to launder illicit proceeds with increased anonymity. Individuals may use a wide array of mechanisms to conceal their physical location, or give the appearance of operating in a different jurisdiction, when accessing a website.”
