Analysis - Drug kingpin's capture spurs hope Mexico can subdue violent cartels

MEXICO CITY (Reuters) - The dramatic capture of the boss of the Zetas drug cartel provides fresh evidence that Mexican authorities are starting to win their protracted fight against a gang that has done more than any other to stain the country's name with its brutality.

But even with Miguel Angel Trevino now in custody, Mexican President Enrique Pena Nieto still has the difficult task of taming other cartels even as he creates a new militarized police force to take over the fight waged for years by the military.
