Author and anthropologist Jason De León spent seven years documenting the lives of “coyotes,” or smugglers who help migrants leave their homes and head for America. He joined Stephen Henderson to talk about his new book, "Soldiers and Kings: Survival and Hope in the World of Human Smuggling," and how political instability, poverty, climate change and other factors are contributing to a perilous journey for migrants and smugglers on the journey through South and Central America to the United States.
