• In mid-2025, a substantial minority of American adults endorse authoritarian views.

• Strong or very strong agreement that civil war was coming and that it was needed were both uncommon and did not increase from 2023 to 2024 (6.5% and 3.6%, respectively, in 2024; 5.7% and 3.8%, respectively, in 2023).

To understand how the implementation and enforcement of universal background check (UBC) laws may influence the use of background checks during private party firearm transfers in the USA.

Following the Supreme Court’s decision in New York State Rifle & Pistol Association, Inc. v. Bruen, which ruled a New York concealed-carry permitting requirement unconstitutional, laws restricting the public carrying of firearms in “sensitive places,” like college campuses, have received increasing attention. However, there is little evidence for whether permissive campus carry policies increase firearm violence or, via deterrence, reduce general crime on campus.

• Many highest-risk dealers consistently sold crime guns across multiple years.
• Our machine learning models accurately identified many high-risk firearms dealers and outperformed simpler prediction approaches.

• Using machine learning with detailed purchase and recovery records could efficiently identify high-risk retailers for targeted enforcement to disrupt the flow of crime guns.
• Opportunities for policy and enforcement action based on our findings include targeting enforcement on the smal

In 2022, a nationally representative longitudinal survey in the USA found concerningly high prevalences of support for and personal willingness to engage in political violence, but those prevalences decreased in 2023. This study examines changes in those prevalences from 2023 to 2024, an election year in the USA.

BACKGROUND

Firearm violence is a major public health problem in the United States, yet most states lack a mechanism to temporarily remove firearms from individuals who are at high and imminent risk of harming themselves or others and are not otherwise prohibited. Extreme risk protection order (ERPO) laws are intended to close this gap. The current study examines the passage of California’s gun violence restraining order (GVRO) bill using Kingdon’s multiple streams framework.

METHODS

The COVID-19 pandemic and resulting social and economic disruptions may be associated with increased risk for reported domestic violence (DV) and firearm-involved DV (FDV). This study examines trends in DV, FDV, and the proportion of DV incidents that involved firearms (FDV/DV) in five large US cities before and during the coronavirus pandemic.

To date, there have been no peer-reviewed studies in the United States estimating the impact of gun-free zone policies in alcohol-serving establishments on rates of firearm violence in and around such establishments. In this study, we utilized a crossectional design to estimate the impact of Texas’s 51% alcohol law, which prohibits the carrying of firearms in establishments that generate over half of their revenue from alcohol sales.
