Why Haiti Asked for an Intervention

This episode contains descriptions of distressing scenes. Haiti is unraveling. Gangs control much of the capital, thousands have been displaced and hundreds more are dead. In recent weeks, the government has taken the extraordinary step of asking for an armed intervention from abroad. What is it like on the ground, and what does the request mean for Haitians? Guest: Natalie Kitroeff, the bureau chief for Mexico, Central America and the Caribbean for The New York Times.
