The summer of 2020 was a hinge point in American history. The murder of George Floyd by Minneapolis police inspired racial justice demonstrations nationwide. At the time, the FBI was convinced that extreme Black political activists could cross the line into domestic terrorism – a theory federal agents had first termed “Black identity extremism.” That summer, Mickey Windecker approached the FBI. He drove a silver hearse, claimed to have been a volunteer fighter for the French Foreign Legion and the Peshmerga in Iraq, and had arrest records in four states that included convictions for misdemeanor sexual assault and menacing with a weapon, a felony. He claimed to the FBI that he had heard racial justice activists speak vaguely of training and violent revolution in Denver.  The FBI enlisted Windecker as a paid informant, gave him a recording device and instructed him to infiltrate Denver's growing Black Lives Matter movement. For months, Windecker spied on activists and attempted to recruit two Black men into an FBI-engineered plot to assassinate the state's attorney general. Windecker's undercover work is the first documented case of FBI efforts to infiltrate the 2020 racial justice movement. Journalist Trevor Aaronson obtained over a dozen hours of Windecker's secret recordings and more than 300 pages of internal FBI reports for season 1 of the podcast series Alphabet Boys.  This episode of Reveal is a partnership with Alphabet Boys and production company Western Sound.  This is an update of an episode that originally aired in September 2023.
