The article says the doctor crouched behind his desk and “fetched” his gun. It doesn’t sound like it was on his person, but maybe in a desk drawer?
Since the man has a right to keep and bear arms, and since the situation proved for anyone why that is, I can’t see him violating anything more than a no-gun zone established by a hospital. I’m sure that’s backed up by law of some kind, but what if it’s a ‘no carry’ zone and not a ‘no gun’ zone?
My sense then is that he wasn’t armed, in the classic sense of the word. I’ve never heard the word “fetched” be used about one who took a gun out of a holster or a pocket.
I don’t know what the technicality would be, but this could be a technicality in favor of the doctor, if the gun really was in a desk drawer.
He's going to be fired, without a doubt.
On the other hand, keeping a gun in an unlocked desk drawer has its own legal hazards.....
