The New York Times reports from Juarez again, this time about how Mexican law enforcement investigates crimes:

The federal government refused to provide statistics on how many arrests had resulted in convictions, how many suspects were still under investigation or how many arrests had proved to be mistakes. But independent reviews by scholars suggest that only about a quarter of crimes in Mexico are ever reported and that only a small fraction ever result in convictions.

Compounding matters is the sheer number of crimes, especially murders. On a single September night in Ciudad Juárez, 18 men were shot to death in a drug treatment center near the border, more than the number of killings all year long in El Paso, just across the Texas border.

This video is also worth watching, if gruesome.
