Law enforcement officers and agencies are frequently requested by schools, businesses and community members for direction and presentations on what they should do if confronted with an active shooter event. The Civilian Response to Active Shooter Events (CRASE) course, designed and built on the Avoid, Deny, Defend strategy developed by ALERRT in 2004, provides strategies, guidance and a proven plan for surviving an active shooter event.

Topics include the history and prevalence of active shooter events, the role of professional guardians, civilian response options, medical issues and drills.
