The "Only Ones" In Mexico

I wonder what a similar experiment would turn up in a major US city?

TIJUANA – The city's entire 2,300-member municipal police force has been ordered to turn in its weapons, leaving doubt Thursday about who would be patrolling this city of more than 1.5 million residents.

The surprise directive from Mexico's Defense Secretariat comes a day after President Felipe Calderon ordered Operation Tijuana, a major offensive against organized crime in the city. More than 3,000 soldiers and federal agents are being sent to the city with the aim of tackling the city's crime problems.

Federal officials were expected to conduct ballistics tests on the weapons, apparently to see if they could link any of the weapons to the many killings that have been attributed to drug cartels.
