What must a public official do upon receiving evidence of a riot?

When a public official receives evidence of a riot, the appropriate action is to act to disperse the crowd. This is because a riot poses an immediate threat to public safety and can escalate further if not controlled. The duty of a public official, particularly one responsible for maintaining order, involves taking prompt action to mitigate danger and prevent harm to individuals, property, and the surrounding community.

Acting to disperse the crowd typically involves employing various methods, which may include directing law enforcement personnel to the scene or using other measures to safely convince individuals to leave the area. This action is essential to restoring peace and ensuring the safety of those involved, bystanders, and property at risk of damage.

This option reflects the proactive responsibilities that public officials have in maintaining the rule of law and ensuring public safety, which is a fundamental aspect of their role in managing disturbances such as riots.
