Modifies provisions relating to self-defense

This Missouri bill replaces the state's self-defense law with updated rules. It allows deadly force to protect against unlawful entry into a home, vehicle, business, or personal property, and removes the requirement to retreat in those locations. The law clarifies that force is justified when a person reasonably believes it's needed to prevent death, serious injury, or a forcible felony. It directly affects individuals claiming self-defense in criminal cases, shifting the burden of proof to the defendant in certain scenarios.
