Here in New York, a federal district judge on Wednesday sentenced Mexico’s former top security official to more than 38 years in prison, following his conviction last year for accepting millions of dollars in bribes from the drug cartels he had been tasked with prosecuting. Genaro García Luna served as Mexico’s secretary of public security under former President Felipe Calderón, the architect of Mexico’s U.S.-backed so-called war on drugs, which has led to the killing and disappearance of tens of thousands of people. García Luna also worked closely with U.S. counternarcotics and intelligence agencies.
