Whenever a law enforcement agency seizes or recovers a firearm that was unlawfully possessed, used for any unlawful purpose, recovered from the scene of a crime, is reasonably believed to have been used or associated with the commission of a crime, or is acquired by the agency as an abandoned or discarded firearm, the agency shall arrange for every such firearm that, in accordance with protocols promulgated by the Attorney General and superintendent, is determined to merit and be suitable for National Integrated Ballistics Identification Network data entry and examination to be test-fired as soon as may be practicable and the results of that test-firing be forthwith submitted to the National Integrated Ballistics Identification Network to determine whether the firearm is associated or related to a crime, criminal event, or any individual associated or related to a crime or criminal event or reasonably believed to be associated or related to a crime or criminal event.

Whenever a law enforcement agency recovers any spent shell casing at a crime scene or has reason to believe that the recovered spent shell casing is related to or associated with the commission of a crime or the unlawful discharge of a firearm, the agency shall, as soon as may be practicable, submit the ballistics information to the National Integrated Ballistics Identification Network.
