Background: Gun-related homicide remains a persistent public health crisis in the United States, with over 48,000 firearm-related deaths reported in 2022, including 19,651 homicides and 27,032 suicides. Despite frequent calls for tighter gun control, firearm access alone does not explain the complexity of violence. Objective: This commentary aims to unpack the socioeconomic, psychological, and biological drivers of gun-related homicide and propose integrative, evidence-based solutions that extend beyond legislative reform. Methods: We synthesized data from peer-reviewed literature, national crime and health databases (e.g., Centers for Disease Control and Prevention and Federal Bureau of Investigation), and international reports. We examined patterns related to poverty, trauma, male aggression, neurobiology, and firearm acquisition, as well as cross-national comparisons with countries like Switzerland and Mexico. Findings: Young males, particularly those aged 10–29, accounted for 50% of homicide offenders in 2022. African Americans experienced homicide rates of 23.1 per 100,000, ten times the rate among Whites. Up to 56% of incarcerated men report childhood physical trauma, and over 40% of those in prison exhibit symptoms of serious mental illness. While firearm legislation varies widely, analysis reveals that over 90% of crime guns are acquired illegally or through informal sources. International comparisons show that poverty and weak rule of law, more than gun laws alone, correlate with elevated homicide rates. Conclusions: Reducing gun violence sustainably requires a multifaceted approach. Authors advocate for investments in trauma-informed mental health care, focused deterrence programs, early childhood interventions, and improved enforcement against illegal gun trafficking. A public health strategy that integrates social reform with targeted regulation holds the greatest promise for long-term change. Full article

Public mass shootings pose a critical safety challenge in the U.S. This study investigates how media framing relates to public online engagement, focusing on gun regulation, mental health, and individual and political accountability across five major TV networks: ABC, CNN, Fox News, MSNBC, and NBC. Using a mixed-methods approach, the research analyzes 678 news reports and 7605 audience comments. Findings reveal significant differences in audience engagement based on framing, and in key variables show audiences taking opposite positions to their news network’s narratives. ABC, CNN, and NBC’s thematic framing, highlighting systemic failures, elicits more balanced responses, whereas Fox News and MSNBC’s episodic framing, emphasizing individual or political accountability, correlates with polarized reactions. This research extends media framing theories by showing how episodic framing reduces support for systemic reforms, emphasizing personal responsibility. The study offers crucial insights for scholars, policymakers, and journalists on media’s role in shaping public discourse on gun violence. Full article

Although the U.S. makes up only 5% of the global population, it accounts for approximately 31% of public mass shootings. Gun violence and mass shootings not only result in loss of life and injury but also inflict lasting psychological trauma, cause property damage, and lead to significant economic losses. We recently developed and published an embedded system prototype for detecting gunshots in an indoor environment. The proposed device can be attached to the walls or ceilings of schools, offices, clubs, places of worship, etc., similar to smoke detectors or night lights, and they can notify the first responders as soon as a gunshot is fired. The proposed system will help to stop the shooter early and the injured people can be taken to the hospital quickly, thus more lives can be saved. In this project, a new custom dataset of blank gunshot sounds is recorded, and a deep learning model using both time and frequency domain features is trained to classify gunshot and non-gunshot sounds with 99% accuracy. The previously developed system suffered from several security and privacy vulnerabilities. In this research, those vulnerabilities are addressed by implementing secure Message Queuing Telemetry Transport (MQTT) communication protocols for IoT systems, better authentication methods, Wi-Fi provisioning without Bluetooth, and over-the-air (OTA) firmware update features. The prototype is implemented in a Raspberry Pi Zero 2W embedded system platform and successfully tested with blank gunshots and possible false alarms. Full article
