Proposes a constitutional amendment relating to firearms

This bill proposes a constitutional amendment to Missouri that protects an individual's right to possess and carry firearms for self-defense and to aid civil authorities. It establishes that restrictions on these rights must meet the strict legal standard of "strict scrutiny" and explicitly exempts convicted violent felons and individuals deemed dangerous due to mental health issues. The amendment allows counties, the city of St. Louis, and the city of Kansas City to create their own local rules regarding firearm possession, carrying, and transfer, provided these rules include specific limits on permit fees, validity periods, and penalties. Additionally, the proposed law grants exemptions for law enforcement, judges, and licensed security guards from local regulations and permits local authorities to use state background check systems for their permits.
