Modifies the offense of unlawful possession of a firearm

HB 2138 redefines when firearm possession becomes unlawful by adding three specific circumstances: (1) having a felony conviction (state, federal, or other state), (2) being a fugitive, habitually intoxicated/drugged, or mentally incompetent, or (3) being under 18 on public property. It includes an exception for those who completed hunter education, and exempts antique firearms from these rules. The bill changes penalties: unlawful possession is a class C felony by default, but becomes a class B felony if the person has a prior dangerous felony conviction or prior unlawful possession. This bill applies directly to individuals meeting these defined conditions, not to the general public.
