“…But the number of mass shootings the U.S. has experienced makes us an extreme outlier in these data. Indeed, Lankford's (2016) international research comes to a similar conclusion with a different sample-nations with high rates of firearm ownership are more at risk of public mass shootings.…”

“…We excluded any case that was coded as having a connection to gang or narcotic activity because one of our supplemental data sets excludes gang‐ or narcotic‐related events. Other studies that have examined mass shooting frequency have excluded gang and narcotic incidents, so we excluded these incidents to adhere to the current literature (Klarevas, ; Lankford, ). We also created a variable that indicated whether a shooting involved a domestic relationship because some laws restrict firearm access based on history of domestic violence.…”

Research Summary We used data from the FBI's Supplemental Homicide Reports and other publicly available databases to calculate state‐level annual incidence of fatal mass shootings for 1984–2017. Negative binomial regression models were used to estimate the associations between changes in key gun laws and fatal mass shootings. Handgun purchaser licensing laws and bans of large‐capacity magazines (LCMs) were associated with significant reductions in the incidence of fatal mass shootings. Other laws commonly advocated as solutions to mass shootings—comprehensive background checks, assault weapons bans, and de‐regulation of civilian concealed carry of firearms—were unrelated to fatal mass shootings. Policy Implications Our findings suggest that laws requiring firearm purchasers to be licensed through a background check process supported by fingerprints and laws banning LCMs are the most effective gun policies for reducing fatal mass shootings.

“…In line with previous scholars' definition of ''mass shootings'' as incidents that result in four or more victim fatalities, the same threshold was used for this study. Consistent with other research on public mass shooters (Blair and Schweit 2014;Kelly 2010;Lankford 2016b), this data set specifically excludes other types of mass murderers who appear psychologically and behaviorally distinct, such as those who are motivated by robbery, burglary, or gang violence or who solely attack in private places such as someone's home. To supplement these data, additional information on the behavior and characteristics of offenders was drawn from scholarly research, government reports, and media reports, all of which have been commonly used by researchers who study mass shooters in the past (Blair and Schweit 2014;Fox and Levin 1994;Huff-Corzine et al 2014;Kelly 2010;Langman 2018;Lankford 2016a).…”

As the threat of public mass shootings continues to be on the forefront of Americans' minds, it begs the question whether there are differences between young and older mass shooters. In general, earlier research suggests that young people are more likely than their older counterparts to commit crimes because of immaturity, lack of impulse control, rebelliousness, peer pressure, poor role models, and the influence of what they see on television or consume through other media content. When it comes to mass shooters, however, the answer to this question may depend on whether ''young'' offenders are defined using the legal age of adulthood or the scientific definition of when brain development typically reaches maturity. This study aims to determine whether significant differences exist between public mass shooters who were younger than or older than 18 years when they attacked, or younger than or older than 25 years when they attacked, by examining 88 offenders who struck in the United States from January 1982 to March 2018. Tests of statistical significance suggest that with both definitions, young mass shooters are more likely than older mass shooters to obtain their weapons illegally, attack at schools, have a reported history of animal abuse, and admit copying or being inspired by previous attackers. These results are interpreted in the context of previous scholarship, and recommendations are provided for future research.

Public Mass Shooters and Firearms: A Cross-National Study of 171 Countries

Abstract: The United States and other nations with high firearm ownership rates may be particularly susceptible to future public mass shootings, even if they are relatively peaceful or mentally healthy according to other national indicators.
