During what phase of an active shooter event is the shooter actively harming individuals?

In the context of an active shooter event, the phase during which the shooter is actively harming individuals is the execution phase. This phase represents the critical moment when the shooter carries out their attack, inflicting injuries or fatalities on victims. During this time, situational awareness becomes paramount for responders, as they must assess the environment to effectively manage the crisis and intervene where necessary.

Understanding this phase is vital for public safety telecommunicators, as it helps in prioritizing responses, relaying clear information to law enforcement, and aiding in the organization of medical assistance for the injured. Each phase of an active shooter event has distinct characteristics and implications for response, making it crucial for emergency responders to recognize and react appropriately to the execution phase.
