During the 1912 San Diego free speech fight, vigilantes aligned with police brought arrested members of the Industrial Workers of the World from the free speech protest in downtown San Diego to Sorrento valley. Vigilantes subjected these protesters to patriot indoctrination and forced them to kneel in front of the flag and sing the "Star Spangled Banner" in-key, which left an unknown number of IWW members dead or injured. Those that survived the ordeal were forcibly exiled from the City of San Diego under the threat of death.
