Taking It to the Cities

The US ambassador to Mexico, Carlos Pascual, is taking a tour through the most dangerous cities in Mexico, first Tijuana, and now Juárez. While in Tijuana, he praised the local police and promised more support from US agencies. I wonder how Los Pinos feels about the idea of US agencies working with local forces. I also wonder if the US, if it indeed does develop a deeper relationship with local police in key border cities, is taking the sufficient precautions to avoid being duped by corrupt departments.
