Fostering security, stability, and democracy in neighbouring Mexico is seen by analysts to be in the U.S. national security and economic interest. Reforming Mexico's often corrupt and inefficient criminal justice system is widely regarded as crucial for combating criminality, strengthening the rule of law, and better protecting citizen security and human rights in the country. Congress has provided significant support to help Mexico reform its justice system in order to make current anticrime efforts more effective and to strengthen the system over the long term. This book provides an overview of Mexico's historic 2008 judicial reforms and an assessment of how those reforms have been implemented thus far. It then analyses U.S. support for judicial reform efforts in Mexico and raises issues for Congress to consider as it oversees current U.S. justice sector programs and considers future support to Mexico.
