Aug 2, 1892: Calgary mob rioted in Chinatown, attacking Chinese laundries & businesses. Local authorities failed to act. The incident began when a Chinese laundry worker contracted smallpox. Civic authorities responded by burning the laundry and quarantining its occupants. After four formerly quarantined individuals returned to Chinatown, a mob of around 300 men, many reportedly intoxicated after watching a cricket match, descended on Chinese laundries. The workers had fled, but the mob vandalized the premises and then moved to a store, injuring two people. Town authorities offered no protection to the victims. However, the North-West Mounted Police intervened, offering refuge in their barracks and patrolling the area for three weeks.
