"8- 6- 1. USE AND POSSESSION OF FIREARMS.
It shall be unlawful for any person, other than a law enforcement officer engaged in the performance of his official duties, to use, or possess with intent to use in any area within the confines of the city limits, whether public or private, any gun, revolver, or firearm of any kind or nature, or air gun, or sling shot, or rubber flipper, or bow and arrow of any other such type instrument designed to propel or throw missiles, unless upon a place specifically designed exclusively for the use of any such type instrument."
"8- 6- 3. UNLAWFUL WEAPONS.
It shall be unlawful for any person except a peace officer, to carry any brass knuckles, firearms, daggers, stiletto, nunchaku stick, or any other instrument or object capable of causing death or serious bodily injury concealed upon his person.
It shall be unlawful for any person, except a peace officer, to carry concealed on his person, any dangerous weapon with the intent or the purpose to use the same to harm, maim, or injure another person, animal, or thing. For the purpose of this subsection:
(A) Dangerous weapon shall mean any item that, in the manner of its use or intended use, is capable of causing death or serious bodily injury; and
(B) In construing whether or not an object or thing not commonly known as a dangerous weapon is a dangerous weapon, the character of the wound produced, if any; and the manner in which the instrument, object, or thing was used or intended to be used, are factors which the court shall take into account in deciding the question."
It looks to me like those folks up in Park City have not heard of State Preemption.
They have illegal laws.
