Globalization is a characteristic of crime as well as of legitimate commerce. Criminal enterprises have become transnational, posing difficult problems of cooperation among law enforcement officials of different states. Illicit drugs sold in the United States come from Mexico whose cartels kill with American guns. Prescription-requiring narcotics (controlled substances used in any year by about 10% of U.S. high school seniors) can be bought without prescription from India by internet. Nigeria has specialized in fraudulent offers to Americans. Russian gangs have the best computer hackers. Terrorists come from the Middle East or south Asia. Pakistani and North Koreans sell weapons of mass destruction. Financial institutions launder money through international transactions.This seminar will explore both the scope of the problem in each of these areas and the capacity and methods available to address such transnational organized crime. Each student will be asked to write a paper on one of these subjects and present her or his research to the class. Taught with Assistant US Attorney, Stephen Heymann.
