What action is required by magistrates or peace officers when a riot occurs?

When a riot occurs, magistrates or peace officers are required to command dispersal or make arrests. This action is critical because it helps to restore order and ensure public safety. The presence of a riot represents a significant disturbance that threatens the peace and can lead to injury or damage. Therefore, law enforcement officials must take decisive action to control the situation. Commanding dispersal involves instructing individuals to leave the area to prevent further escalation of violence or disorder.

Making arrests may also be necessary if individuals are engaging in unlawful behavior during the riot, which can help deter others from participating in similar actions. This proactive approach not only aims to resolve the immediate situation but also serves to uphold the rule of law within the community.

In contrast, ignoring the situation would allow it to escalate, potentially resulting in greater harm. Calling additional units can be part of the response, but it is not the primary action required in the moment of a riot. Establishing a curfew could be a measure taken afterward or in anticipation of similar disturbances, but during an active riot, commanding dispersal or making arrests is the immediate responsibility of the peace officers or magistrates on the scene.
