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.

SALT LAKE CITY (AP) — A military veteran who was trying to stop an alleged gunman and inadvertently shot and killed a demonstrator at a Salt Lake City “No Kings” rally was a “safety volunteer” for the demonstration, according to police and organizers.

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.
