Change of Strategy in Juárez

This from Excélsior:

Change of strategy in the Operation Chihuahua. Starting today, Mexican army troops will leave the urban area of the city and their place will be occupied by around 2,000 Federal Police. In addition, Federal Police helicopters and unmanned airplanes will keep watch over the city.

Considered the most violent city in the world, with 191 homicides per 100,000 residents, the federal government decided to change strategy and take the Mexican army out of the urban area.

Hard to guess if this will have any impact at all, but I guess as long as Juárez remains such a disaster zone, the government can't just sit on its hands. But it might just be that, in the short term at least, the forces driving the violence in Juárez are immune to any government action short of a total lockdown of the city.
