Active Shooter: Recommendations and Analysis for Risk Mitigation

Publication Date: 2012
Abstract: The Department of Homeland Security (DHS) defines an active shooter as an individual actively engaged in killing or attempting to kill people in a confined and populated area. In its definition, DHS notes that, in most cases, active shooters use firearms(s) and there is no pattern or method to their selection of victims. The New York City Police Department (NYPD) has limited this definition to include only those cases that spill beyond an intended victim to others. The NYPD compiled a list of recommendations for building security personnel to mitigate the risks from active shooter attacks. Developed by the NYPD, the recommendations are based on a close analysis of active shooter incidents from 1966 to 2012. A statistical analysis was performed on a subset of these cases to identify common characteristics among active shooter attacks.
