Violence perpetrated by drug trafficking organizations and other criminal groups continues to threaten citizen security and governance in some parts of Mexico, a country with which the United States shares a nearly 2,000 mile border and $500 billion in annual trade. Although the violence in Mexico has generally declined since late 2011, analysts estimate that it may have claimed more than 70,000 lives between December 2006 and December 2013. Supporting Mexico's efforts to reform its criminal justice system is widely regarded as crucial for combating criminality, strengthening the rule of law, and better protecting citizen security in the country.
