Mass casualty and terrorist events are among the most complex challenges faced by public safety, putting strain on local resources and response capabilities at the exact time a coordinated, multijurisdictional response is required. Moreover, they can have a lasting impact on the physical and mental health of responders and community members long after the event has occurred.

The IACP has developed a host of resources to support policing professionals in the prevention of, response to, and aftermath of mass casualty and terrorist events.
