When a riot arises from an unlawful act, such as an assault, terror need not be shown because in every riotous situation there are elements of force and violence that are by their very nature terrifying. When a riot arises from lawful conduct, terror must be shown. For example, if a group of neighbors decides to remove a NUISANCE, such as a pile of malodorous garbage, which would be a lawful activity, but does so in a violent and tumultuous manner, terror would have to be shown before the conduct would constitute a riot. In 1999, the World Trade Organization (WTO) held a five-day meeting in Seattle, Washington. Some 45,000 protesters converged on the meeting, protesting the WTO's stand on everything from the environment to global business to HUMAN RIGHTS. What was supposed to be an organized mass movement quickly degenerated into a rampage through the city, in which buildings were vandalized, stores were looted, and police were attacked. Only one person need be alarmed to fulfill the terror requirement for a riot; in Seattle, the entire city was subjected to the terror.
