I am writing to you to express our concern regarding the negative impact that the public security approach pursued in recent years in Mexico has had upon human rights. When you meet with Mexican President Enrique Peña Nieto this week in Mexico, public security will be one of the main issues on the agenda. The visit offers a critically important opportunity to evaluate the public security crisis that continues to afflict Mexico, with extremely powerful cartels, endemic corruption of police forces, and virtually zero accountability for those who commit crimes.
