FERGUSON, Mo. — Pounding rain and tornado watches didn’t deter hundreds of protesters Monday outside Ferguson police headquarters, where they stayed for almost four hours to mark how long 18-year-old Michael Brown’s body was left in a street after he was fatally shot by police.

Organizers of the four-day Ferguson October protests dubbed the day “Moral Monday” and committed acts of civil disobedience across the St. Louis region. In addition to the initial march on Ferguson police headquarters, protesters blocked the entrance to a major employer, held a loud rally inside St. Louis City Hall, disrupted business at a Ferguson shopping center and three Wal-Mart stores and tried to crash a private fundraiser for a St. Louis County executive candidate where U.S. Sen. Claire McCaskill was scheduled to appear.
