Tijuana, Mexico
The entire Tijuana municipal police force walked off the job last week, after federal agents ordered its members to turn over their weapons in connection with murder investigations. With the 2,300-strong force sidelined in the crime-ridden border city, Mexican President Felipe Calderón dispatched 3,300 federal troops to patrol the streets. Federal authorities suspect that some local police have been selling their guns to the powerful Arellano Felix drug cartel. Attorney General Eduardo Medina Mora said police weapons would be returned once theyd been checked for links to gang-related crimes.
