What additional information must be relayed during an active shooter incident?

During an active shooter incident, it is crucial to relay additional calls for service and any related harmful information, as it provides emergency responders with a comprehensive understanding of the situation. This information enables law enforcement and first responders to assess the scope of the threat, which could include the number of shooters, potential additional victims, and ongoing risks that may not be immediately apparent.

Relaying such details helps responders efficiently allocate resources, plan tactical responses, and prioritize actions based on the severity and immediacy of the situations reported. For example, if there are multiple active threats or reports of individuals trapped or injured in various locations, having that context can significantly improve the response strategy.

Other choices do not encompass the breadth of information needed in such a crisis. While the location of casualties and details about caller identities can be important, they do not provide the wider situational awareness that includes multiple potential victims or ongoing threats. The location of the nearest shelter can be useful but does not directly contribute to assessing the active shooter situation itself. Thus, sharing comprehensive and relevant information about ongoing threats and incidents is paramount during an active shooter event.
