Mexican Marines Kill Drug Lord

Yesterday, Mexican Naval Infantry killed one of Mexico's top drug lords. Apparently, the Navy is viewed as more reliable than Mexico's other security services. The article doesn't indicate how often the 8000 strong Naval Infantry is used for such missions. Historically, navies have been able to stand apart from domestic political disputes because they play less of a role than armies in internal security. This may have made the Naval Infantry ideal for this particular mission, although again I don't know how often Calderon turns to the Navy to solve such problems.
