Since fleeing Cuba for Miami in 1961, Raul Diaz has witnessed all manner of criminal mayhem, from terrorist bombings to rampant corruption to Miami's explosion of cocaine-related homicides. This all took a major toll on both his health and family life; Diaz finally found sobriety in 2012. His new book is Killing the Lieutenant: Fighting Miami's Cocaine Wars, Hunting Griselda Blanco and My Fight to Stay Alive. All this as his native Cuba teeters.
