An innocent bystander was shot and killed at a “No Kings” protest in Salt Lake City on Saturday night. According to the Salt Lake City police, the bystander was mistakenly shot by a self-identified “peacekeeper” at the protest who was associated with the event organizers.

No Kings rallies and marches are planned across the country as a counterprotest to a military parade and festival in Washington, D.C. The capital event coincides with the 250th anniversary of the U.S. Army and will include more than 6,000 soldiers and dozens of tanks and aircraft.
