Mexico’s Drug War and Neoliberal Energy Reforms Could Be Good for Business, Especially Mercenary Companies by Guadalupe Correa-Cabrera
Transnational criminal corporations like the Zetas can be compared to big conglomerates such as Constellis, which is the is the largest and most diverse provider of risk management services and provides, among others, private security services. This corporate group includes a company once named Blackwater, which has been one of the U.S. government’s biggest providers of training and security services. In 2009 Blackwater changed its name to Xe Services as part of a company-wide restructuring plan and in response to a series of scandals. In 2010 a group of private investors purchased Xe’s main assets and created a new company named Academi. The services provided by Blackwater-Xe-Academi resemble some of the Zetas’ main functions, such as the provision (although illegal) of protection services. What is more, a group like the Zetas might need the services of a firm like Academi if its training capacities fall short or if it wishes to expand its operations.
Keep Out! How the U.S. Is Militarizing Mexico’s Southern Border by Jeff Abbott
“The crisis of 2014 gave the excuse for the implementation of the Programa Frontera Sur,” Salvador Lacruz, a migrant advocate working with the Fray Matías de Córdova Human Rights Center in Tapachula, Chiapas, told me at the group’s offices. “Since then, there has been the consolidation of the plan, and the establishment of a border that is the southern border of the United States. Mexico is doing the United States’ dirty work.”
Since the plan’s establishment, the number of migrants captured and deported from Mexico has steadily increased. [...] Vidal Olascoaga said this increase in enforcement has been accomplished by a major escalation of resources. “There is a significant increase in technology that is arriving to the southern border of Mexico [from] the United States,” he said. This includes biometric identification machines, vehicles and drones, and additional training to help Mexican police and military detect migrants.
