BOGOTA (Reuters) - Leading Colombian presidential candidate Gustavo Petro is roundly critical of the U.S.-led war on drugs and has questioned the extradition of a drug kingpin, views that may herald a shakeup of how the Andean nation battles the narcotics industry.
Petro points out that despite billions of dollars in security spending and decades of U.S. pressure to reduce drug production, Colombia remains a top global supplier of cocaine and the site of bloody drug violence.
