While the Mexican cartels do have people in the United States, they do not have enough people so positioned to handle the increased workload of distributing narcotics at the retail level. A wide range of skill sets is required. Some of the tactics involved in moving shipments across the border require skilled workers, such as pilots, while U.S. gang members along the border serve as middlemen and retail distributors. Other aspects of the operation call for people with expertise in manipulating corrupt officials and recruiting human intelligence sources, while a large part of the process simply involves saturating the system with massive numbers of expendable, low-skilled smugglers who are desperate for the money.
The U.S. gangs are crucial in filling the cartel gap north of the border. Members of these border gangs typically are young men who are willing to break the law, looking for quick cash and already plugged in to a network of similar young men, which enables them to recruit others to meet the manpower demand. They are also typically tied to Mexico through family connections, dual citizenship and the simple geographic fact that they live so close to the border. However, the U.S. gangs do not constitute formal extensions of the Mexican drug-trafficking organizations. Border gangs developed on their own, have their own histories, traditions, structures and turf, and they remain independent. They are also involved in more than just drug trafficking and distribution, including property crime, racketeering and kidnapping. Their involvement in narcotics is similar to that of a contractor who can provide certain services, such as labor and protection, while drugs move across gang territory, but drug money is not usually their sole source of income.Click here for the full report, "When the Mexican Drug Trade Hits the Border."
