Modifies the offense of unlawful possession of a firearm to include any minor possessing a firearm on public property

This bill updates Missouri law to make it a felony for anyone under eighteen to possess a firearm on public property. The change applies to minors regardless of whether they have a prior criminal record, though it includes exceptions for hunting, school-sanctioned events, or when accompanied by an adult aged twenty-one or older. By adding this specific rule to the existing statute on unlawful firearm possession, the legislation directly targets youth carrying guns in public spaces while maintaining current penalties for other prohibited individuals.
