In March 2015, the IAB and DHS Office of Health Affairs hosted an Active Shooter Summit, which brought together first responders from major cities in the US and UK to formulate best practices or recommendations on integrated Active Shooter/Hostile Events (ASHE) response. The best practices are focused in 5 areas: policy; planning; medical, rescue and equipment; training and exercises; and incident command, and are captured in the report below. Please note, the report was officially published in September 2015. To view the Summit report, please visit http://www.interagencyboard.org/sites/default/files/publications/Externa....
