How the Mariel boatlift has impacted American immigration policy : Embedded In 1991, a group of men took over a federal prison in rural Alabama. But these men weren't prisoners, they were immigration detainees, all of them from Cuba. And none of them were serving time for a sentence; they were being indefinitely detained. Who were these men? What in the world had brought them from Cuba to a prison in rural Alabama, and what became of them afterward? On the new season of White Lies, hosts Chip Brantley and Andrew Beck Grace set out to find the men who took over the prison and, in the process, unspool a sprawling story of a mass exodus across the sea, back-channel cold war communiques, family separation, and a secret list.
