I was at the KDMC emergency room a month ago after a car crash. My car was destroyed, and I was carrying at the time. I was injured, so I turned my weapon over to one of the Boyd County deputies. He had to ask the ambo guy what to do with it. The paramedic locked it in a safe in the ambo, the. Turned it over to KDMC security ahem they dropped me at he ER. I thought, 'Great, that will be a hassle to get back.' After a CT scan and x-ray,they sent me on my way, and I simply signed for my weapon and they gave it back.
I have had some experiences with KDMC security that were not so positive, and they tend to act like they are cops, and be pretty smug. Pretty decent his time, though.
As far as the sign goes, the is one just like at at my bank in Grayson. I have used it as an example of false claims about CCDW laws in my classes.
