Establishes the "Anti-Red Flag Gun Seizure Act"

HB 459 prohibits Missouri state and local agencies from enforcing any "red flag law" that would seize firearms from citizens without a court trial. It blocks the use of federal funds to support such enforcement and bans law enforcement from complying with federal or state orders requiring firearm seizures. The bill directly affects Missouri residents who might face such seizures and state agencies responsible for law enforcement. Violating the law could trigger $50,000 penalties per incident and allow affected citizens to sue for damages.
