Laws are set to protect kids and adults when dangerous instruments are involved. This applies to driving a car as well as to possession of guns. In Arizona, the law states that kids under the age of 18 are not allowed to carry guns (ARS 13-3111). This law also provides some exceptions where kids are allowed to have and use a gun under certain restricted conditions. For example, a kid can carry a gun if he or she is with a parent, grandparent, qualified hunter, safety instructor, or qualified firearms safety instructor as long as there is permission from a parent or guardian. When involved in lawful hunting or shooting events or marksmanship practice, kids between the ages of 14 and 18 are allowed to be in possession of a firearm (ARS 13-3111). Because there are many exceptions and details in this statute, you may want to read the law or consult a gun expert or lawyer before actually possessing a firearm.
Arizona Law (ARS 13-3101) says that a Deadly weapon is anything that is designed for lethal use, including a firearm.
It is against Arizona law to carry a firearm or any deadly weapon on a school campus (ARS 13-3102).
