This report provides an overview of: Mexican cartels and their operations, including the nature of cartel ties to gangs such as the Mara Salvatrucha; Mexican cartel drug production in the United States; and the presence of Mexican cartel cells in the United States. Mexican cartels allegedly have used their vast financial resources to corrupt Mexican public officials who either turn a blind eye to cartel activities or work directly for them. Since 2005, the Mexican government has made numerous efforts to purge corrupt police. In December 2006, President Felipe Calderón launched operations against the cartels in 9 of Mexico's 32 states. He has pledged to use extradition as a tool against drug traffickers, and sent 73 criminals to the United States as of August 2007, including the alleged head of the Gulf Cartel. This report also examines potential policy approaches to the problem of drug trafficking and violence. Current U.S. and Mexican policy emphasizes interdiction and eradication. Supporters of this policy maintain that these efforts have reduced the supply of drugs in the United States. Critics maintain that Administration officials have refused to release data showing that cocaine prices are falling, suggesting that the drug supply is growing, not shrinking. These critics suggest that more emphasis should be placed on demand reduction in the United States, including drug prevention education and treatment. The Mexican government urges the United States to increase its efforts to reduce U.S. demand for drugs, stating that it cannot succeed in its efforts against the cartels so long as cartels stand to earn billions of dollars annually from the U.S. illicit drug market. Critics of current policy, including the Mexican government, are also calling for increased efforts to combat arms trafficking from the United States to Mexico.
