From Trevor Aaronson at the Intercept, this profile of an informant used by the FBI to infiltrate, record, provide weapons to, and incite violence by Black activists in Denver: The Snitch in the Silver Hearse. Michael Windecker — who had prior convictions for sexual assault of a 14-year-old girl and weapons charges — was paid over $20,000 during the summer of 2020 at the height of Denver protests against the killings of George Floyd and Elijah McClain. Among other astounding things, Windecker drove an activist to the personal home of Colorado Attorney General Phil Weiser (who was overseeing the prosecution of the police and paramedics who killed McClain) where Windecker affirmatively encouraged the activist to kill Weiser. The activist refused.
The FBI has a long sordid history of using informants to infiltrate and disrupt progressive political groups. See previous posts here. For more history, see Elizabeth Hinton, The Unsettling Message of Judas and the Black Messiah in The Atlantic, and Gary Marx’s classic book, Undercover.
