Ohhhh for Christ's sake here we go with that gun grab BS again. Every time the CC worshipers get their panties in a wad they make this ignorant and wild claim. Now that it has clearly been disproved, then someone decides to claim that it will suddenly become the norm. Hogwash!
And having to show need is a argument used by anti gunners. There is no need to show need, CC is not protected under 2A because it is NOT bearing arms. The only time OC can be unrestricted is when OC IS restricted, and restricting OC IS unconstitutional. That is what we should be fighting for, the constitutional carry of firearms openly, ya know "bear arms shall not be infringed".
Is CC more convenient, yes sometimes, sometimes not. But it clearly is not covered. Technically anyone can carry concealed as long as they do it properly and are not involved in any behavior that creates RAS. The Courts have just recently ruled this is the case in NC. I believe the case is Black V State. The problem is, most of the time it is really very hard to properly conceal, unless carrying a mouse gun. And if most people who can discern you are carrying even though there is a piece of cloth over your weapon, where is the need?
