Ioan Grillo Tracks the Rise of 'Gangster Warlords' in Latin America

When Mexican authorities recaptured the infamous Joaquin "El Chapo" Guzman, President Enrique Pena Nieto tweeted "Mission Accomplished." But the truth is far darker: Guzman is just one kingpin in a sprawling network of criminal fiefdoms that extend from the streets of Juarez in Mexico to the favelas in Brazil and the slums of Jamaica. In his newest book, "Gangster Warlords: Drug Dollars, Killing Fields and the New Politics of Latin America," veteran journalist Ioan Grillo goes to the front lines of the drug war to learn how it's changing and what can stop it.
