I agree with other active and retired LEO's who have posted. I work for one of the larger agencies in my state, and we do not perform inventories of locked/secured vehicles prior to towing. We only conduct an inventory when a vehicle is towed due to an arrest, a recovered stolen vehicle, or because of involvement in an accident that has disabled the vehicle. Also, I am not aware of any agency in my state firing all weapons to enter into a database. To the best of my knowledge, weapons are only fired by most agencies if they are seized from a criminal suspect or there is another strong reason to believe that the weapon was used in a crime. We will check recovered guns through NCIC and the ATF to determine if they are stolen, but we do not perform any forensic testing without a reason.
