The bill establishes gun-free and weapon-free zones around schools and public properties in New Jersey, amending N.J.S.2C:39-5 to classify the unlawful possession of a firearm on school grounds or within 1,000 feet of such properties as a third-degree crime, while possession of certain weapons in these zones is classified as a fourth-degree crime. It specifies that ignorance of being within these prohibited areas is not a valid defense and allows for the use of maps depicting the boundaries of these zones as prima facie evidence in prosecutions. The bill also defines "public property safety zones" to include day care centers, public housing facilities, public parks, and public buildings, with penalties for possessing firearms or certain weapons within 500 feet of these zones.

Additionally, the bill introduces new requirements for law enforcement and correctional personnel regarding firearms training and qualifications, mandating successful completion of a firearms training course and annual qualification for individuals such as county correctional police officers and campus police officers. It allows retired law enforcement officers who meet specific criteria to carry handguns under certain conditions, including submitting a written application to the Superintendent of State Police every two years. The bill emphasizes the importance of training and safety in handling firearms while establishing clear penalties for violations of the new regulations, thereby aiming to enhance public safety in sensitive areas frequented by children and the general public.
