Must a peace officer have a warrant to arrest a person engaged in a riot?

A peace officer does not need a warrant to arrest a person engaged in a riot due to the nature of public safety and the immediate response required in such situations. When a person is involved in a riot, they are actively participating in unlawful behavior that poses a danger to public order and safety. The law allows for the arrest of individuals involved in these circumstances without a warrant because the situation may require swift action to prevent further escalation, protect citizens, and maintain order.

In riot situations, officers are often acting under the authority granted to them during emergencies, where obtaining a warrant could delay their response and potentially result in harm to the public or damage to property. Additionally, laws typically provide that individuals involved in certain types of civil disorder can be detained to restore order, making the ability to act without a warrant crucial for law enforcement in such scenarios. This allows officers to uphold the law effectively and respond to threats as they arise.
