In which scenario is crowd dispersal deemed necessary?

Crowd dispersal is deemed necessary when safety is compromised. In situations where the safety of attendees, staff, or property is at risk, it's critical to take action to manage the crowd effectively. This can occur due to various factors such as violent behavior, potential hazards, overcrowding, or any other scenario that poses a threat to safety. The immediate priority in such circumstances is ensuring the well-being of everyone involved, thereby necessitating crowd dispersal to mitigate risks.

Other choices represent scenarios where crowd dispersal would not be appropriate or necessary. For example, if an event is running smoothly, it implies that there are no immediate concerns regarding safety or order. Dispersing a crowd under such conditions would disrupt the event without justification. Likewise, boredom among attendees or breaks during intermissions do not warrant dispersal; these situations can be managed through other means, such as engaging activities or procedural intermissions, rather than resorting to dispersal.
