Weapons and drug trafficking are among the largest underground industries in the world. Generating hundreds of billions of dollars in annual revenue, and spawning a global industry of money laundering, trafficking has profound effects not only in the developing world but also in the well-established economies of Europe, Asia and North America. Trafficking leads also to a series of collateral social issues including increased crime rates, profound societal effects and costs, rampant public corruption and large-scale funding of terrorist activities. This course familiarizes students with the origins and present state of international trafficking in weapons and drugs and the money laundering practices used to conceal it from detection. It includes an examination of how trafficking is conducted on a global scale, what efforts have been undertaken to combat it, and what the international community is doing to address the many complex issues involved. International standards and cross-cultural obstacles are examined, as are political implications. The course will examine the approaches to these problems used in countries that have a strong interest or participation in trafficking. In addition, international best practices and standards will be critically assessed.
