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

This bill updates the law on unlawful firearm possession to explicitly make it a crime for anyone under eighteen to have a gun on public property. The change applies to minors who are alone with a firearm in public areas, though they are exempt if accompanied by an adult aged twenty-one or older or if the gun is used for specific activities like hunting or school events. Possession of a firearm under these new rules is classified as a class D felony, with stricter penalties for those with prior dangerous felony convictions. The law also clarifies that this restriction does not apply to antique firearms.
