Modifies provisions relating to unlawful use of weapons

HB 2266 replaces Missouri's current law on unlawful use of weapons with specific prohibitions. It bans carrying concealed weapons in restricted areas (like schools, churches, and government buildings), discharging firearms near occupied buildings, and possessing weapons while intoxicated. The bill exempts law enforcement officers, prison staff, and military personnel acting in official duties, even when carrying weapons in restricted locations. This clarifies what constitutes a violation but does not change existing penalty levels for the offense.
