Chapter 10.58 DISCHARGING FIREARMS
It is unlawful to discharge within the city limits any pistol, firearm, airgun, musket or instrument of any kind, character or description, which throws a bullet or missile for any distance by means of the elastic force of air, or any explosive substance except in a regularly licensed shooting gallery or range or in accordance with the provisions of a permit authorized by the city council and issued by the chief of police. In granting such a permit the city council shall impose such conditions in connection therewith as are reasonably necessary to protect the health and safety of persons and property. (Prior code § 19-35)
Better not get caught in Jack-in-the-Box while shooting the wrapper off of your straw with a healthy puff of air or you'll go away for "Discharging Firearms".
