What should not be restricted in a riot control scenario?

In a riot control scenario, the number of personnel involved is crucial for effectively managing the situation without escalations. Having adequate personnel can provide a sense of security and control, allowing for a strategic approach to de-escalate tensions within the crowd. When the personnel numbers are sufficient, it ensures that the responding forces can effectively engage the situation with appropriate crowd management techniques.

Other options, such as time considerations, the type of crowd present, and the use of verbal commands, are elements that can and should be adjusted or tailored based on the specific context of the riot. For instance, time considerations might focus on how quickly action needs to be taken to prevent escalation, while understanding the type of crowd is essential for anticipating behaviors and tailoring responses. The use of verbal commands is a technique that can be utilized as needed, but should also take into account the current dynamics of the situation. Hence, these elements can be controlled or restricted, unlike the number of personnel, which should be as robust as necessary to maintain order.
