I am also in charge of the security at our building, and get 'the call' when the alarm goes off. Have had to meet officers there multiple times. The most recent, after I got my CHL.
It is worth noting, that I live 15 minutes away from my office. I have beaten the officers there _every time_ (probably half a dozen)
One time, I beat them there, and still waited another 30 minutes for them to arrive.
I did not notify them I was carrying, as they did not request my ID. I also was on property that I controlled, as the security representative of my company, so technically, I could have probably even open-carried, or exposed my handgun while walking through the building with the officers. I did not, however.
Had they requested my ID, I would have happily provided it and my CHL.
