Fame through surprise: How fame-seeking mass shooters diversify their attacks.

Mass shootings are becoming more frequent in the United States, as we routinely learn from the media about attempts that have been prevented or tragedies that destroyed entire communities. To date, there has been limited understanding of the modus operandi of mass shooters, especially those who seek fame through their attacks. Here, we explore whether the attacks of these fame-seeking mass shooters were more surprising than those of others and clarify the link between fame and surprise in mass shootings. We assembled a dataset of 189 mass shootings from 1966 to 2021, integrating data from multiple sources. We categorized the incidents in terms of the targeted population and shooting location. We measured "surprisal" (often known as "Shannon information content") with respect to these features, and we scored fame from Wikipedia traffic data-a commonly used metric of fame. Surprisal was significantly higher for fame-seeking mass shooters than non-fame-seeking ones. We also registered a significant positive correlation between fame and surprisal controlling for the number of casualties and injured victims. Not only do we uncover a link between fame-seeking behavior and surprise in the attacks but also we demonstrate an association between the fame of a mass shooting and its surprise.

Evaluating the impact of a street outreach intervention on participant involvement in gun violence.

The past several years have witnessed increased calls for community violence interventions (CVIs) that address firearm violence while centering local expertise and avoiding the criminal legal system. Currently, little evidence exists on CVI effectiveness at the individual level. This study presents an evaluation of the impact of a street outreach-based CVI [Chicago CRED (Create Real Economic Destiny)] on participant involvement in violence. We used a quasiexperimental design with a treatment sample of 324 men recruited by outreach staff from 2016 to 2021 and a balanced comparison sample of 2,500 men from a network of individuals arrested in CRED's service areas. We conducted a Bayesian survival analysis to evaluate CRED's effect on individual violence-related outcomes on three levels of treatment: All enrolled participants, a subsample that made it through the initial phase, and those who completed programming. The intervention had a strong favorable effect on the probability of arrest for a violent crime for those completing the program: After 24 mo, CRED alumni experienced an 11.3 percentage point increase in survival rates of arrest for a violent crime relative to their comparisons (or, stated differently, a 73.4% reduction in violent crime arrests). The other two treatment levels experienced nontrivial declines in arrests but did not reach statistical significance. No statistically significant reduction in victimization risk was detected for any of the treatment levels. Results demonstrate that completion of violence intervention programming reduces the likelihood of criminal legal involvement for participants, despite the numerous systemic and environmental factors that impede personal success.

Society for Maternal-Fetal Medicine Position Statement: Gun violence and pregnancy.

Position: The Society for Maternal-Fetal Medicine acknowledges gun violence as a public health crisis in the United States, with a substantial impact on pregnant and postpartum people. We recognize the urgent need for a robust, equitable, data-driven approach to mitigate the impact of access to firearms and accompanying violence on pregnant and postpartum individuals and communities. As such, the Society for Maternal-Fetal Medicine endorses the following policy principles.

National Burden of Injury and Deaths From Shootings by Police in the United States, 2015‒2020.

Objectives. To describe all-outcome injurious shootings by police and compare characteristics of fatal versus nonfatal injurious shootings nationally. Methods. From July 2021 to April 2023, we manually reviewed publicly available records on all 2015-2020 injurious shootings by US police, identified from Gun Violence Archive. We estimated injury frequency, case fatality rates, and relative odds of death by incident and victim characteristics. Results. A total of 1769 people were injured annually in shootings by police, 55% fatally. When a shooting injury occurred, odds of fatality were 46% higher following dispatched responses than police-initiated responses. Injuries associated with physically threatening or threat-making behaviors, behavioral health needs, and well-being checks were most frequently fatal. Relative to White victims, Black victims were overrepresented but had 35% lower odds of fatal injury when shot. Conclusions. This first multiyear, nationwide analysis of injurious shootings by US police suggests that injury disparities are underestimated by fatal shootings alone. Nonpolicing responses to social needs may prevent future injuries. Public Health Implications. We call for enhanced reporting systems, comprehensive evaluation of emerging reforms, and targeted investment in social services for equitable injury prevention.

Disadvantaged Neighborhoods Continue to Bear the Burden of Gun Violence.

INTRODUCTION: Gun violence is a pervasive and dynamic public health crisis causing substantial burden on communities and healthcare systems in the United States. Risk factor and outcome analyses are crucial to develop effective interventions. The aim of this study was to assess firearm injury in a diverse community setting as it relates to neighborhood socioeconomic disadvantage and changes over time following large-scale local interventions. METHODS: All county residents with firearm injury presenting to a Level 1 Trauma Center from January 2012 to December 2021 were retrospectively reviewed. Area Deprivation Index (ADI) was used to measure neighborhood socioeconomic disadvantage based on a nine-digit zip code at patients' home address. Injuries were also stratified by 5-year time periods, 2012-2016 and 2017-2021. Demographics and clinical data were analyzed including injury severity, hospital course, and discharge location. Data were compared by ADI quintile and between time periods using chi-squared, one-way analysis of variance, and Cochran-Armitage test. RESULTS: A total of 1044 injuries were evaluated. Patients were 93% male with mean age of 29 y (standard deviation 10.2) and were concentrated in the most disadvantaged neighborhoods (74% ADI Q5). Black or African American race was greater in the most disadvantaged ADI groups (76% versus 47%-66%; P <0.001). Percentage of total injuries in the most disadvantaged ADI group rose from 71% to 78% over time (P = 0.006). Mortality occurred in 154 (15%) patients overall, while most (71%) were discharged to home. Mortality declined from 18% to 11% over time (P <0.001). Medicaid utilization rose from 42% to 77% alongside a decrease in self-pay status from 44% to 4% (P <0.001). There were no clinically significant group differences in injury severity or clinical characteristics. CONCLUSIONS: Firearm injury remains concentrated in the most socioeconomically disadvantaged neighborhoods, and this disparity is increasing over time. Medicaid utilization rose and mortality decreased in this population over time. This research presents a method to inform and monitor local gun violence interventions using ADI to address public health equity.

Nearly 20 Years Since the Federal Ban: Can State-Level Assault Weapon Prohibitions Fill the Void? Comparative Analysis of Case Fatality and Assault Weapon Recovery in States With and Without an Assault Weapon Ban.

INTRODUCTION: Few states established assault weapon bans (AWBs) after the federal AWB expired. The effectiveness of state AWBs as well as neighboring state legislation, in reducing the local prevalence of assault weapons (AWs) or in reducing overall shooting lethality is unknown. METHODS: We queried the Gun Violence Archive (2014-2021) to identify US firearm injuries and fatalities. Shooting case fatality rates were compared among states with and without AWBs, as reported in the State Firearm Laws Database. Data on recovered firearms was obtained from the ATF Firearms Trace Database and used to estimate weapon prevalence. Recovered firearms were classified as AWs based on caliber (7.62 mm, 5.56 mm, 0.223 cal). We performed spatially weighted linear regression models, with fixed effects for state and year to assess the association between geographically clustered state legislation and firearm outcomes. RESULTS: From 2014 to 2021, the US shooting victim case fatality rate was 8.06% and did not differ among states with and without AWBs. The proportion of AWs to total firearms was 5.0% in states without an AWB and 6.0% in states with an AWB (mean difference [95% CI] = -0.8% [-1.6% to -0.2%], P = 0.03). Most recovered firearms in AWB states originated from non-AWB states. On adjusted models, there was no association between state-level AWB and firearm case fatality; however, adjacency to states with an AWB was associated with lower case fatality (P < 0.001). Clustered AWB states with shared borders had lower AW prevalence and fatality rates than the rest of the US. CONCLUSIONS: Isolated state AWBs are not inversely associated with shooting case fatality rates nor the prevalence of AWs, but AWBs among multiple neighboring states may be associated with both outcomes.

Firearm-Related Injuries and the US Opioid and Other Substance Use Epidemic: A Nationwide Evaluation of Emergency Department Encounters.

INTRODUCTION: There has been a sharp climb in the Unites States' death rate among opioid and other substance abuse patients, as well as an increased prevalence in gun violence. We aimed to investigate the association between substance abuse and gun violence in a national sample of patients presenting to US emergency departments (EDs). METHODS: We queried the 2018-2019 Nationwide Emergency Department Sample for patients ≥18 years with substance abuse disorders (opioid and other) using International Classification of Diseases, 10th Revision, Clinical Modification codes. Within this sample, we analyzed characteristics and outcomes of patients with firearm-related injuries. The primary outcome was mortality; secondary outcomes were ED charges and length of stay. RESULTS: Among the 25.2 million substance use disorder (SUD) patients in our analysis, 35,306 (0.14%) had a firearm-related diagnosis. Compared to other SUD patients, firearm-SUD patients were younger (33.3 versus 44.7 years, P < 0.001), primarily male (88.6% versus 54.2%, P < 0.001), of lower-income status (0-25th percentile income: 56.4% versus 40.5%, P < 0.001), and more likely to be insured by Medicaid or self-pay (71.6% versus 53.2%, P < 0.001). Firearm-SUD patients had higher mortality (1.4% versus 0.4%, P < 0.001), longer lengths of stay (6.5 versus 4.9 days, P < 0.001), and higher ED charges ($9269 versus $5,164, P < 0.001). Firearm-SUD patients had a 60.3% rate of psychiatric diagnoses. Firearm-SUD patients had 5.5 times greater odds of mortality in adjusted analyses (adjusted odds ratio: 5.5, P < 0.001). CONCLUSIONS: Opioid-substance abuse patients with firearm injuries have higher mortality rates and costs among these groups, with limited discharge to postacute care resources. All these factors together point to the urgent need for improved screening and treatment for this vulnerable group of patients.

Urban Teen Perspectives on Gun Violence: a Mixed Methods Study.

We aimed to explore perspectives of teenagers on their exposure to gun violence (GV), their knowledge and attitudes towards firearm injury prevention (FIP) efforts, and how to counsel them about FIP. Teens from two single-sex Bronx Catholic high schools participated in videoconferencing focus groups. Participants completed an online survey collecting demographic information and Likert-scale scoring of attitudes towards GV. Quantitative data was analyzed with descriptive statistics. Focus group discussions were recorded and transcribed. Using Dedoose, two investigators independently coded data and achieved consensus using content analysis. Six focus groups (3 from each school, n = 28 participants) were held from October-November 2020. A total of 27 participants completed the survey. Eighty-one percent of respondents agreed "Doctors should talk to teens about gun safety." During focus groups, participants reported personal, community, and entertainment media exposure to GV. GV elicited many emotions, including fear and frustration. Teens identified factors contributing to GV that should be addressed, including poverty, racism, and mental illness. Most had not received prior FIP education and desired more information from trusted adults. They preferred discussions over written materials and information given over time. Teens were open to doctors counseling on FIP during healthcare visits and suggested including screening questions on surveys, conversations during healthcare maintenance visits, and classroom talks by physicians. Bronx teens are exposed to and distressed by community GV. They desired more FIP education, including physician counseling during healthcare visits. Next steps are to create and test FIP guidance for adolescents.

Community-Academic Partnership to Assess the Role of Physical Disinvestment on Firearm Violence in Toledo, OH.

Reversing physical disinvestment, e.g., by remediating abandoned buildings and vacant lots, is an evidence-based strategy to reduce urban firearm violence. However, adoption of this strategy has been inconsistent across US cities. Our community-academic partnership sought to support adoption in Toledo, OH, USA, by generating locally relevant analyses on physical disinvestment and firearm violence. We used a spatial case-control design with matching. Physical disinvestment measures were derived from a citywide parcel foot audit conducted by the Lucas County Land Bank in summer 2021. Firearm violence outcomes were incident-level shootings data from the Toledo Police Department from October 2021 through February 2023. Shooting locations were matched to controls 1:4 on poverty rate, roadway characteristics, and zoning type. Exposures were calculated by aggregating parcels within 5-min walking buffers of each case and control point. We tested multiple disinvestment measures, including a composite index. Models were logistic regressions that adjusted for the matching variables and for potential spatial autocorrelation. Our sample included N = 281 shooting locations and N = 1124 matched controls. A 1-unit increase in the disinvestment score, equal to approximately 1 additional disrepair condition for the average parcel within the walking buffer, was associated with 1.68 times (95% CI: 1.36, 2.07) higher odds of shooting incidence. Across all other measures, greater disinvestment was associated with higher odds of shooting incidence. Our finding of a strong association between physical disinvestment and firearm violence in Toledo can inform local action. Community-academic partnership could help increase adoption of violence prevention strategies focused on reversing physical disinvestment.

Situational and Victim Correlates of Increased Case Fatality Rates in Los Angeles Shootings, 2005-2021.

The gun assault case fatality rate measures the fraction of shooting victims who die from their wounds. Considerable debate has surrounded whether gun assault case fatality rates have changed over time and what factors may be involved. We use crime event data from Los Angeles to examine the victim and situational correlates of gun assault case fatality rates over time. We estimated log binomial regression models for the probability of death in each year from 2005 to 2021, conditioned on situational and victim characteristics of the crime. Case fatality rates increased by around 1.3% per year between 2005 and 2021 from around 15.9 to 19.7%. Baseline case fatality rates differed systematically by most situational and victim but followed similar temporal trends. Only victim age significantly covaried with the temporal trend in case fatality rates. An individual shot in Los Angeles in 2021 was 23.7% more likely to die than the equivalent victim in 2005. The steady increase in case fatality rates suggests that there were around 394 excess fatalities over what would have occurred if case fatality rates remained at the 2005 level. Increases in the average age of victims over time may contribute to the general temporal trend. We hypothesize that older victims are more likely to be shot indoors where lethal close-range wounds are more likely.

Emergency Preparedness Drills for Active and Mass Shootings in Schools.

PURPOSE OF REVIEW: There is widespread use of emergency preparedness drills in public K-12 schools across the US, but considerable variability exists in the types of protocols used and how these practices are conducted. This review examines research into both "lockdown drills" and "active shooter drills" as it relates to their impact on participants across different outcomes and evaluations of their procedural integrity. RECENT FINDINGS: A number of studies on lockdown drills yielded largely consistent findings about their impacts, whereas findings related to the effects of active shooter drills are less uniform. The research also demonstrated that lockdown drills, though not active shooter drills, can help participants build skill mastery to be able to successfully deploy the procedure. Differences in how drills impact participants and whether they cultivate skill mastery are largely attributable to the type of drill being conducted. This review suggests that employing clearly defined drill procedures incorporating best practices, coupled with instructional training, can help schools prepare for emergencies without creating trauma for participants.

Public health framing of firearm violence on local television news in Philadelphia, PA, USA: a quantitative content analysis.

BACKGROUND: Firearm violence is an intensifying public health problem in the United States. News reports shape the way the public and policy makers understand and respond to health threats, including firearm violence. To better understand how firearm violence is communicated to the public, we aimed to determine the extent to which firearm violence is framed as a public health problem on television news and to measure harmful news content as identified by firearm-injured people. METHODS: This is a quantitative content analysis of Philadelphia local television news stories about firearm violence using a database of 7,497 clips. We compiled a stratified sample of clips aired on two randomly selected days/month from January-June 2021 from the database (n = 192 clips). We created a codebook to measure public health frame elements and to assign a harmful content score for each story and then coded the clips. Characteristics of stories containing episodic frames that focus on single shooting events were compared to clips with thematic frames that include broader social context for violence. RESULTS: Most clips employed episodic frames (79.2%), presented law enforcement officials as primary narrators (50.5%), and included police imagery (79.2%). A total of 433 firearm-injured people were mentioned, with a mean of 2.8 individuals shot included in each story. Most of the firearm-injured people featured in the clips (67.4%) had no personal information presented apart from age and/or gender. The majority of clips (84.4%) contained at least one harmful content element. The mean harmful content score/clip was 2.6. Public health frame elements, including epidemiologic context, root causes, public health narrators and visuals, and solutions were missing from most clips. Thematic stories contained significantly more public health frame elements and less harmful content compared to episodic stories. CONCLUSIONS: Local television news produces limited public health coverage of firearm violence, and harmful content is common. This reporting likely compounds trauma experienced by firearm-injured people and could impede support for effective public health responses to firearm violence. Journalists should work to minimize harmful news content and adopt a public health approach to reporting on firearm violence.

Fatal Firearm Violence Among American Indians and Alaska Natives.

There is a dearth of population-based studies regarding firearm-related deaths and years of potential life lost among American Indians and Alaska Natives (AI/AN). Using the Centers for Disease Control and Prevention's (CDC) We Based Injury Statistics Query and Reporting System (WISQARS) data for the three most recent years (2018-2020), we analyzed the demographic characteristics of AI/ANs who succumbed to firearm violence. AI/ANs averaged almost 500 firearm-related deaths per year. The majority of these deaths were observed among individuals 20-39 years of age (53%), males (84.4%), and in the West (55.3%). A plurality of these firearm-related deaths were suicides (48.9%) followed by homicides (43.5%). During the 3-year study period, the age-adjusted firearm death rate increased almost 5 times the growth of the AI/AN population. Also, a staggering 67,050 years of potential life were lost before the age of 80 years (YPLL80) during this period. Firearm suicides were responsible for the largest proportion of YPLL80s (48.5%). Traditional legal interventions [e.g., child access prevention (CAP) laws and extreme risk protection orders (ERPO)], if expanded to more states could potentially help reduce AI/AN firearm mortality. None of the 10 states with the highest firearm mortality of AI/AN have ERPOs and 8 of the 10 do not have CAP laws. Also, a renewed focus on cultural continuity and indigenous protective factors is essential to ameliorate the level of firearm violence in AI/ANs.

Firearm Mortality of Non-Hispanic Black Americans by Law Enforcement, 2011-2020.

Law enforcement officers in the U.S. are more likely to use lethal force against non-Hispanic Black citizens than on their non-Hispanic White counterparts. The purpose of this study was to assess estimates of the national prevalence of fatal firearm violence by law enforcement officers (LEOs) against non-Hispanic Black Americans. The Web-Based Injury Statistics Query and Reporting System (WISQARS) from the Centers for Disease Control and Prevention (CDC) were analyzed using descriptive statistics and joinpoint regression from 2011 to 2020. During the decade (2011-2020) LEOs fatally shot 5,073 citizens and 1,170 were non-Hispanic Black (23%). The vast majority (96%) were males and two-thirds (66%) of those killed were ages 20-39 years. The region with the highest number of LEO fatal shootings was the Western U.S. Firearm deaths of non-Hispanic Blacks were the dominant (82%) method of LEO-induced deaths. Non-Hispanic Black Americans experience LEO firearm-related injuries and deaths at a much higher rate than their non-Hispanic White counterparts. In the context of the racial disparities among people who die following LEO-related gunshot wounds, changes to police training systems and an examination of implicit biases among LEOs should be investigated as the next step in reducing the use of lethal force practices.

The echo chamber effect on social media.

Social media may limit the exposure to diverse perspectives and favor the formation of groups of like-minded users framing and reinforcing a shared narrative, that is, echo chambers. However, the interaction paradigms among users and feed algorithms greatly vary across social media platforms. This paper explores the key differences between the main social media platforms and how they are likely to influence information spreading and echo chambers' formation. We perform a comparative analysis of more than 100 million pieces of content concerning several controversial topics (e.g., gun control, vaccination, abortion) from Gab, Facebook, Reddit, and Twitter. We quantify echo chambers over social media by two main ingredients: 1) homophily in the interaction networks and 2) bias in the information diffusion toward like-minded peers. Our results show that the aggregation of users in homophilic clusters dominate online interactions on Facebook and Twitter. We conclude the paper by directly comparing news consumption on Facebook and Reddit, finding higher segregation on Facebook.

An Academic-Community Partnership to Address Gun Violence in the Roseland Neighborhood of Chicago.

BACKGROUND AND OBJECTIVES: Gun violence is the leading cause of death for youth. This study examined an academic-community partnership to address gun violence through a strength-based approach called Asset-Based Community Development. METHODS: We used a case study design. Participants were Black youth who encounter frequent gun violence (average age = 16.7 years; 72% male). Our partnership involved survey development/completion and semistructured discussions. We also interviewed community stakeholders to collect data on local assets. We interpreted data through a communitywide forum to guide social action to address gun violence. RESULTS: The majority of youth (76%) witnessed neighborhood violence in the last year. The top youth concerns related to gun violence included poverty, guns, and gangs. Community stakeholders saw local people and local organizations as primary community assets. A community forum to interpret these data led to social action in the form of an environmental strategy-cleaning up an unused commercial building for the development of a youth tech center. The majority of youth participants (89.5%) agreed or strongly agreed that they had a voice in the research process. CONCLUSION: Participatory research that takes an asset-based approach can enable relevant inquiry that engages youth and guides social action to address gun violence.

"We been dying, and you got me on a call helping you stay alive": Black and Latinx youth organizers' experiences of racism in gun violence prevention organizations.

This study explored Black and Latinx youth organizers' experiences of racism within national gun violence prevention organizing spaces. Interview data were analyzed from 17 Black and/or Latinx youth (Mage = 20.17, 47% women) across the United States who organized against gun violence. The findings identified three forms of racism that Black and Latinx organizers experienced in national organizations: (1) being tokenized for their racial identities and experiences without having real decision making power; (2) feeling a burden to educate their white peers about the structural causes of gun violence and how to improve organizing spaces for other youth of color; and (3) being silenced in their racially conscious organizing efforts to address the structural causes of gun violence in their communities. This research highlights how Black and Latinx youth gun violence prevention organizers contend both with structural racism in their everyday lives and racism in organizing spaces.

Patterns in pro-gun beliefs and weapon carrying behaviors in rural White adolescent.

Weapon carrying among White rural populations is understudied although evidence suggests that rural White boys have high rates of carriage. This study delineated patterns of weapon use and pro-gun beliefs using a latent class analysis on a sample of 32,916 White rural adolescents. Five groups were identified (i.e., Low Gun Risk, Naïve, Social Contagion, Independent, Unsupervised) using pro-gun beliefs, peer risk factors, and weapon carrying items. Multinomial logistic regression analyses revealed that identifying as male, age, housing instability, and victimization consistently differentiated group membership between different classes. These results suggest that rural White adolescents vary in their belief systems about guns and weapon carrying behavior and that this heterogeneity can be differentiated by lived experiences of these adolescents.

Surveillance of Gun-Related Conversations on Twitter.

Gun violence in the USA is a documented public health crisis. Publicly accessible data from Twitter posts can be used to rapidly capture and describe the public's recent conversations about guns. Because these gun-related conversations change rapidly, it is important to provide regularly updated information on them. Twitter posts containing gun-related terms were obtained from January 1, 2022 to June 30, 2022. To understand topics of gun-related tweets (N = 449,492), topic modeling was performed with Top2Vec. Gun ownership control, concern about gun safety and its impact on children and schools, and the Second Amendment were major areas of the gun-related discourse on Twitter. Several identified topics in this study were a consequence of the study period, including "Discourse on Capitol Riots," and "Wartime and Military Use of Guns," with the latter topic containing conversations about the Russia-Ukraine War. Conversations around the influence of the National Rifle Association (NRA) on gun policies and pro-gun ownership perspectives were also part of the public discourse. The intersection between alcohol, substance use, and gun use was infrequently observed. Findings suggest that gun-related conversations in social media such as Twitter can inform public health researchers.

Community exposure to gun homicide and adolescents' educational aspirations.

INTRODUCTION: Witnessing violence and violent victimization have detrimental effects on adolescents' emotional functioning and ability to envision and plan for their futures. However, research is limited on the impact of violence that occurs in adolescents' communities-whether or not it was witnessed or experienced firsthand. This paper investigated the associations between community exposure to gun homicide and adolescents' high school and college graduation aspirations. METHODS: We analyzed data from the Future of Families and Child Wellbeing Study (N = 3031), a cohort study of children born 1998-2000 in 20 large US cities, merged with incident-level data on deadly gun violence from the Gun Violence Archive (2014-2017). Outcomes were reported by adolescents (girls and boys) during wave 6 (2014-2017) of the study, conducted when the children were 15 years of age. We employed ordinary least squares regression, ordered logistic regression, and multilevel stratification to examine the average and heterogeneous impacts of community exposure to gun homicide on adolescents' educational aspirations. RESULTS: Community exposure to gun homicide was associated with reduced high school graduation aspirations, particularly among adolescents with the lowest risk of exposure to gun homicide. Gun homicide exposure was also associated with increased college graduation aspirations; this association was concentrated among adolescents with moderate-high risk of exposure. CONCLUSIONS: Given the importance of education for job opportunities and the better health that accompanies education and occupational attainment, preventing early exposure to gun violence and providing institutional supports to help adolescents facing adversity realize their goals is essential to their long-term health and success.
