HB 2101 proposes to require the Texas Department of Public Safety to conduct a study on unreported gunshots detected using gunshot detection technology. The department is directed to contract with three municipal police departments, each located in a city with a population exceeding 500,000. The study aims to collect data on the number of unreported gunshots, investigate their intent, and determine any resulting criminal charges. Eligible municipal police departments must submit an application detailing geographic areas with high rates of unreported gunshots, their experience with gunshot detection technology, and a proposed five-member committee to assist with the study. The participating departments are required to submit findings by September 1, 2026, and the Department of Public Safety must provide a comprehensive report to the legislature by December 31, 2026. The bill has an expiration date of September 1, 2027.
