Which of the following is not one of the ways to control crowds?

In crowd control, the goal is to manage large groups of people in a way that ensures safety and order. Each of the first three options—mojo barriers, caution tape, and retractable posts—are physical methods designed to guide and manage the movement of crowds effectively. Mojo barriers are typically used to create defined pathways or enclosures, helping to prevent crowd surges. Caution tape serves as a visual barrier, indicating areas that are off-limits or need to be avoided, and is often used in conjunction with other crowd control strategies. Retractable posts also play a similar role by providing a flexible means to direct crowd flow and maintain order.

In contrast, relying on excessive verbal commands is not considered an effective method for crowd control. While verbal communication is important in guiding and instructing individuals during crowded situations, an overload of verbal commands can create confusion, anxiety, and potentially escalate situations within a crowd. Therefore, the reliance on excessive verbal commands does not align with established crowd control practices, making it the correct answer as it does not help manage crowd dynamics effectively.
