This document provides an overview of active shooter training for library employees presented by Dr. Steve Albrecht. It discusses the need for such training given the "new" stressful environment libraries face with patrons experiencing mental illness and substance abuse issues. The training teaches employees to change their behavior under stress using concepts of "run, hide, fight" and emphasizes the importance of preparation and muscle memory during live threatening incidents. It provides guidance on assessing threatening behaviors, partnering with law enforcement, conducting drills, and addressing staff concerns in the aftermath of traumatic events.
