Gold-plated handguns. Million dollar pieces of art. Exotic wildlife. These and other ostentatious symbols of wealth were reportedly found at some of the properties formerly owned by Joaquin “El Chapo” Guzman – Mexico’s top drug kingpin. But it was the bulk cash, mostly in carefully stacked $100 notes, that caught my attention. Reports from Mexico speculate the money recovered could eventually exceed one billion dollars…According to experts at the Financial Action Task Force, bulk cash smuggling is one of the three principal international money laundering methodologies.
