What constitutes a riot under the legal definition?

A riot is typically defined as a situation in which a group of people engages in violent or disorderly conduct that disrupts public peace. The correct choice indicates that a minimum of three individuals is involved in activities that disturb the peace. This aligns with legal definitions that often specify the number of participants necessary to categorize an assembly as a riot, distinguishing it from a simple unlawful gathering.

The emphasis on "disturbing the peace" highlights that the activities must not only be unlawful but also demonstrably disruptive to the community or public order. This understanding is crucial, as it sets the threshold for what qualifies as a riot as opposed to other forms of assembly or protest that might not involve violence or significant disorder.

The other options do not accurately capture the legal definition of a riot. An unlawful assembly could occur with just two people, and simply gathering without permission or having a permitted protest does not align with the specific criteria needed to label an incident as a riot, particularly regarding the element of disturbance.
