Officer-Involved Shootings and Concealed Carry Weapons Permitting Laws: Analysis of Gun Violence Archive Data, 2014–2020

By Mitchell L Doucette, Julie A Ward, Alex D McCourt, Daniel Webster, Cassandra K Crifasi

About 1,000 civilians are killed every year by a law enforcement officer in the USA, more than 90% by firearms. Most civilians who are shot are armed with firearms. Higher rates of officer involved shootings (OIS) are positively associated with state-level firearm ownership. Laws relaxing restrictions on civilians carrying concealed firearms (CCW) have been associated with increased violent crime. This study examines associations between CCW laws and OIS. We accessed counts of fatal and nonfatal OIS from the Gun Violence Archive (GVA) from 2014–2020 and calculated rates using population estimates. We conducted legal research to identify passage years of CCW laws. We used augmented synthetic control models with fixed effects to estimate the effect of Permitless CCW law adoption on OIS over fourteen biannual semesters. We calculated an inverse variance weighted average of the overall effect. On average, Permitless CCW adopting states saw a 12.9% increase in the OIS victimization rate or an additional 4 OIS victimizations per year, compared to what would have happened had law  adoption not occurred. Lax laws regulating civilian carrying of concealed firearms were associated with higher incidence of OIS. The increase in concealed gun carrying frequency associated with these laws may influence the perceived threat of danger faced by law enforcement. This could contribute to higher rates of OIS.

The Emergence of 3D-Printed Firearms: An Analysis of Media and Law Enforcement Reports

By Stefan Schaufelbühl , Nicolas Florquin , Denis Werner , Olivier Delémont

3D-printed firearms, an emerging category of privately made firearms (PMF) produced beyond government control, have become increasingly prevalent due to technological advancements. They are now emerging as a cost-effective and reliable alternative to conventional firearms. Raised to public awareness following the 2013 release of the 3D-printed Liberator, these firearms are now more commonly encountered by police forces. This article analyses various reports involving 3D-printed firearms, reflecting the increasing encounters by law enforcement agencies. It examines 186 cases involving 3D-printed firearms, primarily from North America, Europe, and Oceania, highlighting a significant rise in incidents since 2021. These incidents include seizures, illicit uses, and online sales, with the firearms typically being hybrid models, Parts Kit Completions/Conversions (PKC), or firearm components such as auto sears. The study underscores the use of affordable equipment and materials for production, emphasizing the accessibility and potential risks of these firearms.

Violent Extremism: A handbook of risk assessment and management

By Caroline Logan, Randy Borum, and Paul Gill

Violent extremism has galvanized public fear and attention. Driven by their concerns, the public has pushed for law enforcement and mental health systems to prevent attacks rather than just respond to them after they occur. The prevention process requires guidance for practitioners and policymakers on how best to identify people who may be at risk, to understand and assess the nature and function of the harm they may cause, and to manage them to mitigate or prevent harm. Violent Extremism provides such guidance.

Over 10 chapters, prepared by leading experts, this handbook illuminates the nature of violent extremism and the evolution of prevention-driven practice. Authors draw on the literature and their experience to explain which factors might increase (risk factors) or decrease (protective factors) risk, how those factors might operate, and how practitioners can prepare risk formulations and scenario plans that inform risk management strategies to prevent violent extremist harm.

Each chapter is crafted to support thoughtful, evidence-based practice that is transparent, accountable and ultimately defensible. Written for an international audience, the volume will be of interest to law enforcement and mental health professionals, criminal justice and security personnel, as well as criminologists, policymakers and researchers.

Transphobic discourse and moral panic convergence: A content analysis of my hate mail

By Michelle Sydes, Lorelei Hine, Angela Higginson, James McEwan, Laura Dugan, Lorraine Mazerolle

Background: Criminal justice agencies are well positioned to help prevent the radicalisation of individuals and groups, stop those radicalised from engaging in violence, and reduce the likelihood of terrorist attacks. This Evidence and Gap Map

(EGM) presents the existing evidence and gaps in the evaluation research. Objectives: To identify the existing evidence that considers the effectiveness of criminal justice interventions in preventing radicalisation, violent extremism and terrorism.

Search Methods: We conducted a comprehensive search of the academic and grey literature to locate relevant studies for the EGM. Our search locations included the Global Policing Database (GPD), eight electronic platforms encompassing over 20 academic databases, five trial registries and over 30 government and nongovernment websites. The systematic search was carried out between 8 June 2022 and 1 August 2022.

Selection Criteria: We captured criminal justice interventions published between January 2002 and December 2021 that aimed to prevent radicalisation, violent extremism, and/or terrorism. Criminal justice agencies were broadly defined to include police, courts, and corrections (both custodial and community). Eligible populations included criminal justice practitioners, places, communities or family members, victims, or individuals/groups who are radicalised or at risk of becoming radicalised. Our map includes systematic reviews, randomised controlled trials, and strong quasi‐experimental studies. We placed no limits on study outcomes, language, or geographic location.

Data Collection and Analysis: Our screening approach differed slightly for the different sources, but all documents were assessed in the systematic review software program DistillerSR on the same final eligibility criteria. Once included, we extracted information from studies using a standardised form that allowed us to collect key data for our EGM. Eligible systematic reviews were assessed for risk of bias using the AMSTAR 2 critical appraisal tool.
