The security guy likely doesn't give two craps about what the law is, nor does he know. He sees a gun, and he says "get out." That's it's own issue. It does NOT mean "The hospital bans guns." That is a separate issue that you guys are inferring from what the guard did.
False. Both of the lead security guys are former LEO. One was a trooper for over 30 years and the other worked for HCSD for over 20.
