"We have tremendous respect for law enforcement, and we thank the Office for bringing this to our attention. We will be sure to reinforce store training regarding our firearm policy with specific regard to uniformed law enforcement," [my emphasis]
I didn't see any quotation of any policy, but just comments that Kay's had posted online somewhere, this being one of them. It sounds like they may have (or change to) a policy allowing uniformed officers to bring in weapons. It sounds like they are showing some special accommodation for some government agents.
