From the Introduction: "[I]n 2014, two U.S. Department of Justice offices--the Office of Community Oriented Policing Services (COPS Office) and the National Institute of Justice (NIJ)-- provided funding to the National Police Foundation (NPF) to develop and maintain an Averted School Violence (ASV) database. [...] In 2019, the NPF conducted a preliminary analysis of 51 cases of averted school violence in the ASV database to identify basic information about the schools involved, the perpetrators and suspects, the weapons, and the plots and incidents. Also in 2019, the NPF conducted a comparison of 51 averted and 51 completed school attacks from the ASV database to identify important similarities and differences between the types of incidents. There are now more than 230 cases in the ASV database: more than 170 averted attacks and more than 60 completed attacks. With more than three times the number of averted cases as there were when the 2019 preliminary analysis was conducted, this report leverages the data from the additional cases to conduct similar analyses; compare the findings from the new cases to the initial 51 averted cases; and provide overarching lessons learned and recommendations that can be leveraged by school administrators, law enforcement, and communities to enhance school safety and security."
