There are a few basic laws out of that 400 page book that every LEO should know. I don't expect one to have everyone of them memorized but the basics are necessary. Things such as possession of a BB gun or that concealed permits including reciprical permits exist should be a basic knowledge. I don't really expect him to know the details of what states qualify but know that some do and check to see if they do. As my college professors used to tell us that we can't possibly know everything they tried to teach us but we should know how to find the information when we needed to.As for knowing the law, the academies don't teach everything there is to know about firearms law and most officers really aren't that knowledgeable in that area. In my state there is a 400 pg book published just on the firearms laws for LEOs . . . very few LEOs ever read it or try to understand it. I worked for the PD for 17 years as a Reserve PO, qualified with fellow officers and know how ignorant they are on the gun laws here. I've had our chief ask me about the gun laws. I'm aware of a situation where someone was arrested for "possession of a BB gun without a license" . . . there is no such thing in this state and no requirement for any license for BB guns.Please, what state are you in so I can avoid it or at least not carry in it. As with the fellow from NC if I get stopped I plan to tell the officer that I have a gun but have no intention of using it unless I have to. If the meer fact that I am legally carrying a gun causes a felony stop and that kind of fear out of a police officer then something needs to change. I don't know where you are talking about but I have never seen or heard of such of a reaction from any LEO around here and to make comments like that does the officers around here a disservice that they do not act like that.If you announce that you are carrying in my state, expect a felony stop! Many POs don't even know that citizens can carry a gun legally here and their reaction is likely to be predictable and unpleasant.
