In some of our countries, the government investment in infrastructure, sometimes hide money laundering. How can that the proven? If the president orders to "assign" multi-million projects to a company owned by a drug-trafficker (later on extradited to the U.S.), he MUST be getting money back under the table. Both, the president and the drug trafficker, get clean money, while investing dirty money. (Please, refer to Dominican Republic's President, Leonel Fernandez and Nelson Solano Guzman's case).
