What is the minimum number of people required to initiate a riot under Title 18?

The minimum number of people required to initiate a riot under Title 18 is indeed two. This legal definition reflects the understanding that a riot involves a collective action wherein individuals are acting together, rather than an isolated incident. The requirement for at least two people indicates that when individuals gather and create public disorder with intent, it reaches the threshold of a riot. This aligns with the legal perspective that public safety is threatened when multiple individuals engage in violent or tumultuous behavior, distinguishing it from lesser offenses like disorderly conduct which may not necessitate a group.

In contrast, defining a riot with only one person would undermine the concept of a collective disturbance necessary for such a classification. Also, having three or more would be unnecessary for establishing the basic criteria of a riot, as it is the act of group coordination with intent to disrupt peace that defines the offense. Therefore, two individuals successfully meet the legal requirement for instigating a riot, as they can act in unison to create the necessary disorder.
