Gun Free Zones in Alcohol-Serving Establishments and Risk for Firearm Violence: A Cross-Sectional, Geospatial Study in Texas.

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 cross-sectional 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. The analysis focused on the difference in shooting incidents in and around establishments with and without firearm carrying prohibitions in 2021 and 2022. After adjusting for establishment type (bar/restaurant), alcohol sales volume, census tract level demographic factors, and the number of nearby restaurants and bars, results indicated that gun-prohibiting bars experienced significantly fewer shootings compared to those that allowed guns. Specifically, establishments that were gun-prohibited had 37% fewer shootings within 50 m than those that were gun-allowing, with a 95% confidence interval ranging from 60% fewer to 0.2% fewer. This association was more prominent in bars than in restaurants. The protective association with gun-prohibited status diminished with increased distance from the establishments; results were not significant at 100 m. Our study findings align with research suggesting that gun-free zones can reduce firearm violence. However, future studies using quasi-experimental designs that can better support causal inference are needed to support such a conclusion, as are studies exploring the efficacy of such policies in various settings and over longer periods.
