EL PASO – The Mexico Institute at the Woodrow Wilson International Center for Scholars has created a resource that provides background information on the major criminal groups battling for control of territory and lucrative drug trafficking routes in Mexico. Casualties have escalated to more than 30,000 people killed in drug-related violence since Mexican President Felipe Calderon began to crackdown on cartels. More than 50 U.S. citizens were killed in Ciudad Juarez in the past two years. “Given the extreme violence in Mexico, the United States in particular is looking at ways to support Mexican efforts against organized crimes,” said Eric L. Olson, author of A Profile of Mexico’s Major Organized Crime Groups and senior associate at The Mexico Institute. Olson said that President Barack Obama favors U.S. support of anti-drug Mexican efforts and that the U.S. has acknowledged partial responsibility for the situation in Mexico because of U.S. consumption of illicit drugs.
