In 2020, the US experienced the largest 1-year increase in homicide since 1960. The spike began in the first few months of the year, accelerating during the COVID-19 pandemic, emergency measures, the murder of George Floyd, and social protests.1 Three additional observations are relevant. First, the US Centers for Disease Control and Prevention (CDC) reported that the homicide increase in 2020 was due to firearm injuries. While the overall homicide rate increased 28.4%, the firearm homicide rate increased 34.6%.2 Second, the spike in violence was concentrated within certain demographic groups. CDC researchers found 19 384 victims of firearms homicide in 2020.3 Of those victims, 61% were Black individuals, and they experienced firearm homicide at 14 times the rate of White indviduals in 2020. This racial disparity does not exist for other types of violence.4 Third, the largest increases in death by firearm homicide were for Black men aged between 10 and 44 years old

This study examines the innovative use of firearms related evidence to enhance violent crime investigations in New Jersey. This effort changed the use of firearms forensic evidence from a sole evidential focus to one that also incorporates a premonitory focus required to generate investigative leads. This project demonstrated the critical importance of fusing firearms forensic evidence such as ballistics imaging with locally available information, such as arrest and incident data on a statewide basis. This study further demonstrated the value of ballistics imaging to connect previously unconnected incidents, individuals, and weapons particularly when combined with other law enforcement data sets. This project demonstrated the critical importance of fusing firearms forensic evidence such as ballistics imaging with locally available information, such as arrest and incident data on a statewide basis. This study further demonstrated the value of ballistics imaging to connect, previously unconnected incidents, individuals, and weapons particularly when combined with other law enforcement data sets. It illustrated the critical need of information sharing across forensic, criminal intelligence (such as fusion and real time crime centers), and investigative entities across all levels of government – local, state, and federal - in supporting violent crime suppression efforts. The study is a mixed methods approach to policy analysis using both quantitative and qualitative analysis. The researchers’ analyzed ballistics imaging submissions over a multi-year period in addition to examining open source and agency documents that tracked many of the crime reduction projects the New Jersey State Police incorporated into their crime gun intelligence effort.

Surges in firearm sales after mass shootings have been well documented in the United States. This study presents three main findings regarding the impact of mass shootings on firearm demand and the moderating roles played by political and regulatory climates. First, mass shootings led to an immediate but temporary increase in gun sales. This effect continued for approximately 3–6 months after the incidents and was larger for shootings with a greater number of fatalities. Second, the association between mass shootings and gun sales was significant only under Democratic presidents. The party affiliation of the state legislature and state-level gun control did not moderate this association. Third, the increased firearm sales after mass shootings did not result in a higher level of firearm ownership. It appeared most purchases were made by current gun owners stockpiling additional firearms, thus indicating the fear of stricter gun control as a likely motivation. This study offers the following policy implications: (a) the public debates concerning gun violence could have the unintended consequence of raising gun demand among current owners, (b) the message of tightening gun control could increase the total stock of firearms in circulation, and (c) the regulations to prevent future mass shootings may be better addressed by the state government as a state-level regulation does not trigger demand response among potential consumers.
