calderon vows to press on...,

Washington Post | Mexican President Felipe Calderón on Thursday defended the deployment of the military in his fight against drug cartels, vowing that the army would continue to patrol cities until the country's weakened and often-corrupt police forces were retrained and able to do the job themselves.

In a speech commemorating the founding of the Mexican army, Calderón suggested that drug bosses had paid marchers who took to the streets this week to protest the army's presence in a dozen cities, where soldiers man roadblocks, search houses and make frequent arrests.

Calderón, who has sent more than 45,000 troops to fight the cartels, said the military would remain on patrol until the government had control of the most violent parts of the country and civil authorities were fully able "to confront this evil." Only then, he said, "will the army have completed its mission."

Turf battles involving the drug traffickers, who are fighting the army, police and one another in order to secure billion-dollar smuggling routes into the United States, took the lives of more than 6,000 people in Mexico last year. The pace of killing has continued in 2009, with more than 650 dead, most in the violent border cities of Ciudad Juarez and Tijuana. In the past few days, a running gun battle between soldiers and gunmen through the streets of the northern city of Reynosa, captured live on television, left five people dead. In Ciudad Juarez, the assistant chief of the city police department was ambushed Tuesday and assassinated with three other officers.
