INTERPOL's definition of money laundering is: "any act or attempted act to conceal or disguise the identity of illegally obtained proceeds so that they appear to have originated from legitimate sources".
Money laundering penalties : pay twice the value of the money laundered (up to $500,000) and be sentenced to serve a prison sentence based on any underlying felonies that accompany the money laundering charges (such as enterprise corruption, securities fraud or drug trafficking charges): [18 U.S.C Section 1956].
