Modifies provisions relating to additional protections to bear arms

HB 2660, titled the "Second Amendment Preservation Act," aims to protect Missouri residents' gun rights by prohibiting state officials from enforcing certain federal firearm laws it deems unconstitutional. It requires investigations into law enforcement officers who knowingly violate Second Amendment rights and creates legal avenues for citizens to seek court relief against such violations. The bill declares Missouri's opposition to federal gun regulations that restrict firearm ownership, possession, or use within the state, arguing these exceed federal constitutional authority. It directly affects state officials, law enforcement, and gun owners by establishing a framework for state-level resistance to federal gun policies.
