After a lethal engagement, what priority should be addressed first?

In the context of an active shooter incident, the immediate priority after a lethal engagement is security. This is crucial because ensuring a secure environment allows for the safe provision of medical assistance and minimizes the risk of further harm or escalation. The primary concern should be to assess and confirm that there is no ongoing threat, protecting both responders and any potential victims.

Once security is established, then medical assistance can be directed to those who need it, as effective medical response cannot occur safely in the absence of security. Establishing ongoing security means assessing for any other potential threats, reassessing the scene, and ensuring that law enforcement can take control of the situation seamlessly.

After security has been assured, an immediate action plan can be implemented to guide the next steps in response, followed by debriefing once the situation is stabilized. The focus on security above all else aligns with best practices in emergency response and incident management.
