Despite high rates of unintentional firearm injuries, and recognition by the National Rifle Association (NRA) that firearm education is important, it is often said that firearm injuries occur primarily among inexperienced users and that firearm safety comes with experience and training. To investigate this contention, we conducted a study in which we hypothesized that firearm use would decline during the dates of NRA meetings — which attract tens of thousands of members from across the United States, including firearm owners and owners of venues where firearms are used (e.g., firing ranges and hunting grounds) — and that firearm injuries would also decline even among experienced users.
