ABSTRACT
This chapter provides an overview of how money service businesses (MSBs) are used by criminal elements throughout the United States to launder money derived from human smuggling and narcotics traffi cking. There is considerable attention given to the U.S. Southwest border, specifi cally Arizona, in detailing how these operations are conducted and many of the related dimensions associated with this illegal industry. The scenarios and circumstances presented here are played out numerous times each day in this never-ending game of cat and mouse between law enforcement and the smugglers they are trying to stop. Each side continually adapts and evolves according to necessity, survival, and environmental demands.
