Now my interpretation. I am not law enforcement. I am not a lawyer. To my knowledge, Trigger Dr. is not currently a lawyer nor law enforcement either. But he apparently was some sort of law enforcement in the past, he claims. No offense - I claim to be a Navy Officer, but you don't know that to be a fact over the internet...
9.41.050 is titled "Carrying Weapons". It regulates carrying weapons, openly and concealed. Many people falsely assume that because vehicle carry is under 9.41.050 that vehicle carry is automatically considered concealed carry because the first section of 050 prohibits concealed carry by non-cpl's. That simply is not true because of the title of 050. Vehicle carry is completely a separate issue, not related to concealed carry.
(1)(a) and (b) of 050 applies to a person either inside a vehicle or not. So that forbids you from carrying a pistol, loaded or not, concealed upon your person either inside or outside a vehicle without a CPL.
(2)(a) Starts out by saying: "A person shall not carry or place a loaded pistol in any vehicle unless the person has a license to carry a concealed pistol and". SO... if the pistol is unloaded, in a vehicle, none of the further restrictions apply to that pistol, because you have not met the loaded criteria for the remaining restrictions to apply.
(3)(a) Does not apply to a pistol CARRIED or TRANSPORTED in a vehicle. If the law was going to apply to a pistol carried or transported in a vehicle, that is what it would say. But (3)(a) says "LEFT" in a vehicle. "LEFT" is the past tense of "LEAVE" which implies absence. Another indication of "LEFT" implying absence is found in (2)(a)..."(iii) the licensee is away from the vehicle and the pistol is locked within the vehicle and concealed from view from outside the vehicle."
So why does (3)(a) not mention "the person is away from the vehicle" like (2)(a) does? That is because (2)(a) is regulating the "CARRYING" of a pistol in a vehicle. (3)(a) is NOT regulating the carrying or transportation of a pistol in a vehicle, because you don't see the word carry or transport anywhere in (3)(a). You cannot apply (3)(a) requirements to the carrying of a pistol, because it is only regulating pistols "LEFT" in vehicles. When you leave a pistol in a vehicle, and you are not a CPL holder, that pistol must be concealed from view from outside the vehicle and locked within the vehicle, which merely means that the vehicle must be locked, at a minimum. It also means the pistol must be unloaded, because you couldn't place a loaded pistol in the vehicle in the first place. It does not regulate the carrying of a pistol.
Now, 9.41.060 is titled "EXCEPTIONS". It is not titled "REQUIREMENTS" or anything similar. It is titled "EXCEPTIONS". 060 provides for no REQUIRED method of carry by anyone. All it is saying is the 050 does not apply to pistols that are carried unloaded and cased. That's all. It does not REQUIRE carry by that method either inside or outside a vehicle. 060(9) prevents you from being cited for concealing a pistol by means of a proper case or wrapper because, in that instance, the pistol itself would not be in view.
SO, an unloaded pistol, carried openly, by a non-CPL holder in a vehicle violates no statutes: Not 050(1) because it is not carried upon the person in a concealed manner, Not 050(2) because it is not loaded, and not 050(3) because it is being carried and not "left", and not 060(9) because 060(9) is not a requirement, it is an exception. A statement that all provisions of 9.41.050 apply to concealed pistols and therefore vehicle carry is considered concealed carry is false because the title of 050 is "CARRYING FIREARMS" and applies to all methods of carry, concealed and open.
Notice that I feel I have supported my position by citing applicable laws. I would appreciate any statement such as "A pistol in a vehicle is considered concealed" to be backed up either by statute or by a citation of case law precedence.
