I don't think it was a weird sign, just an advisement that the mall doesn't want to allow firearms or weapons to be carried by civilians on its property. Although it's possible that the mall's policy is "no concealed carry, but open carry is OK," I tend to doubt it. The mall is more likely just not enforcing its policy thoroughly and just missed noticing you. And whoever drafted the sign text probably just didn't think or know about open carry, so they only specified "concealed" weapons. One way to find out would be to go to the mall and open carry again. Then stop by the security station and ask them if you're "OK." If the mall's policy is actually "no guns allowed," they will inform you of such and then you can tell them what your objections to that might be and that you won't shop there again, etc
That was the weird thing. Every other place I've seen would have a sign saying "no deadly weapons." The interesting thing is that the sign is actually illegal, because KRS 527.020 tells me that a concealed permit holder can legally carry concealed anywhere a person can carry unconcealed.
KRS 527.020 subsection 4:
Persons, except those specified in subsection (5) of this section, licensed to carry a
concealed deadly weapon pursuant to KRS 237.110 may carry a firearm or other
concealed deadly weapon on or about their persons at all times within the
Commonwealth of Kentucky, if the firearm or concealed deadly weapon is carried
in conformity with the requirements of that section. Unless otherwise specifically
provided by the Kentucky Revised Statutes or applicable federal law, no criminal
penalty shall attach to carrying a concealed firearm or other deadly weapon with a permit at any location at which an unconcealed firearm or other deadly weapon may be constitutionally carried.
No person or organization, public or private, shall
prohibit a person licensed to carry a concealed deadly weapon from possessing a
firearm, ammunition, or both, or other deadly weapon in his or her vehicle in
compliance with the provisions of KRS 237.110 and 237.115. Any attempt by a
person or organization, public or private, to violate the provisions of this subsection may be the subject of an action for appropriate relief or for damages in a Circuit Court or District Court of competent jurisdiction.
huh... I love uninformed business owners.
