The 'No Kings' protest in Salt Lake City was struck by violence when a man allegedly brandished a rifle near the crowd.

An innocent bystander at a “No Kings” protest in Utah was shot and killed by a “peacekeeper” who was aiming for a different man pointing an AR-15-style rifle toward the crowd, witnesses told Salt Lake City police.

Utah 50501, the organizers of Saturday's protest in downtown Salt Lake City, say there was an "imminent threat" to protesters before the deadly shooting.
