Active shooter

Police use of force, while infrequently used, is a tremendous concern to public safety in the United States when officers employ it excessively or inappropriately, causing injury or death and eroding public trust in law enforcement. This plenary from the 2023 NIJ Research Conference describes the Integrating, Communications, Assessment, and Tactics (ICAT) de-escalation training program developed by the Police Executive Research Forum to guide officers in defusing critical incidents.

Mass public shootings continue to threaten communities in the United States, yet research on this criminal phenomenon is limited. In this full thematic panel, renowned experts will present a series of research projects summarizing NIJ-funded research projects’ newest findings on public mass shootings. The discussion will focus on NIJ’s investment to address the phenomenon of mass shootings through innovative study approaches to advance our understanding of mass shootings and inform prevention efforts. The implications of this research to criminal justice will also be discussed.
