Adam Isacson writes from Medellín, where he describes his visit to the Casa de Paz: “The sole resident of the Casa de Paz is Francisco Galán, an ELN guerrilla leader whom the government captured in the mid-1990s. Galán is very unlikely to attempt an escape: from his previous jail cell in Itagüí, south of Medellín, and elsewhere, he has long served as the main conduit between the ELN and the outside world – including the Colombian government.”
