The uprising after George Floyd's murder on May 25, 2020 — the broadest protest wave in American history, with participation estimated between 15 and 26 million — met the most aggressive federal response ever mounted against domestic protest. Attorney General William Barr directed U.S. Attorneys and the Joint Terrorism Task Forces to prioritize protest cases, publicly framing the unrest as the work of "antifa" agitators; within months the Justice Department had charged over 300 defendants federally, converting conduct normally handled in state court — arson, curfew violations, gun counts — into federal cases carrying mandatory minimums.

Researchers who tracked the docket found the "outside agitator" theory empty: defendants were overwhelmingly local, young, and without organizational ties, and prosecutions clustered in districts whose U.S. Attorneys embraced the directive. Federal charging also served pretrial ends — defendants were detained as flight risks and "threats to the community" for offenses their states would have bailed. The dragnet established the George Floyd cases as a distinct cohort of political prisoners, sentenced under a policy explicitly announced as a response to a protest movement.
