A man who was believed to be part of a peacekeeping team for the “No Kings” protest in Salt Lake City shot at a person who was brandishing a rifle at demonstrators, striking both the rifleman and a bystander who later died at the hospital, authorities said Sunday.

Arrests were almost exclusively for charges of failure to obey a lawful order, Denver police said, but some included interference with police authority, unlawful throwing of projectiles, and obstruction of streets.
