The proposed bill, known as the Responsible Gun Ownership Act, establishes the crime of unlawful storage of a firearm in the state of Kansas. It defines unlawful storage as the act of storing or leaving a firearm unsecured, which could allow access by a minor. The bill outlines specific circumstances under which a firearm is considered unlawfully stored, including instances where a minor accesses the firearm, uses it to cause bodily harm, or uses it to inflict great bodily harm or death. Penalties for violations vary based on the severity of the incident, with a class C misdemeanor for unauthorized access, a severity level 9 felony for causing bodily harm, and a severity level 5 felony for causing great bodily harm or death.

Additionally, the bill provides certain defenses against violations of unlawful storage, such as if the firearm was inoperable, within the owner's immediate control, accessed by a minor who unlawfully entered the storage area, or used by a minor in lawful defense. The act defines "minor" as any person under 18 years of age and states that it will be part of the Kansas criminal code. The act will take effect upon publication in the statute book.
