This bill aims to enhance the safety and security of service weapons used by Federal law enforcement officers. It directs the head of each civilian or military Federal law enforcement agency to establish requirements for the safe locking and storage of service firearms when they are not in use, and to provide the necessary equipment to comply with these standards. The legislation outlines minimum storage standards, including officers' responsibility to use devices like smart guns, trigger locks, or safes, and generally prohibits storing service firearms in vehicles except under specific circumstances. Any violation of these requirements will result in disciplinary action. Furthermore, agencies are mandated to report any loss or theft of service firearms to relevant State and local law enforcement, as well as to the Bureau of Alcohol, Tobacco, and Firearms and the Federal Bureau of Investigation. Finally, the bill requires agencies to provide training on safe storage practices to personnel assisting in law enforcement functions and to distribute written materials to officers detailing the statistical risks associated with keeping firearms at home, especially if easily accessible. Appropriations are authorized to carry out these provisions.
