The deadly white supremacist rally in Charlottesville nearly one year ago shocked the country. But Mike German, a retired FBI agent who infiltrated neo-Nazi groups in the 1990s, says the violence at 2017’s bloody “Unite the Right” rally “was not just predictable, but predicted.” Subscribe on YouTube: bit.ly/1BycsJW This is a scene from "Documenting Hate: Charlottesville," a joint documentary from FRONTLINE and ProPublica in which correspondent A.C. Thompson investigates why, nearly a year after the rally, many of the perpetrators of racist violence have not been held accountable; traces the origins and actions of the white supremacist groups they belong to; and reveals how a series of violent clashes involving some of those very same individuals and groups preceded the deadly rally in Charlottesville.
