The "Law-Enforcement Innovate to De-Escalate Act of 2025" aims to modernize federal firearms laws by exempting certain less-than-lethal projectile devices from existing restrictions under Title 18, United States Code. This initiative acknowledges technological advancements in less-lethal weapons designed for de-escalation purposes. The bill defines these devices as those not designed to expel conventional ammunition or high-velocity projectiles, and not readily convertible to lethal firearms. Specifically, they must be intended for use in a manner not likely to cause death or serious bodily injury, and cannot accept ammunition feeding devices loaded through a pistol grip or commonly used in semiautomatic firearms. To ensure clarity, the Attorney General must determine if a device meets this definition within 90 days of a request.
