It is hereby declared as a matter of legislative determination that in order to promote and protect the health, safety and welfare of the public, it is necessary and in the public interest to provide a system of identifying persons who are not qualified to acquire or possess firearms, firearm ammunition, stun guns, and tasers within the State of Illinois by the establishment of a system of Firearm Owner's Identification Cards, thereby establishing a practical and workable system by which law enforcement authorities will be afforded an opportunity to identify those persons who are prohibited by Section 24-3.1 of the Criminal Code of 2012, from acquiring or possessing firearms and firearm ammunition and who are prohibited by this Act from acquiring stun guns and tasers.
