Just when you think you have heard it all....
It sounds silly, but it strikes me as a smart move. The cops with slingshots are patrolling alongside soldiers with firearms. Ideally, they should have all been suspended while the authorities investigate which ones are more crooked than Bill Clinton's schwantz, but that wasn't practical, and this way it's easier to keep an eye on them.
I salute the Mexican authorities for finally doing something about all the cops in bed with the narcoterrorists, and I hope the Tijuana operation provides a model that can be rolled out to Juarez, Nogales and Matamoros, among others.
