I think he's saying that if you don't any ID on you, if you get stopped, LE will take a dim view of you having a readily accessable gun.
I got lucky once in this situation.
I had taken my pistol to a friend's farm so he could try it out (as well as another friend who brought a pistol or two, our buddy wanted to try some things before buying). It ended up snowing while we were there and I had a 30 minute or so (normal) drive home in the falling snow on backroads (was out in Horneytown).
Well, stupid me, I was distracted and forgot the gun in the car.
Next morning I leave for work...left wallet at home.
Got pulled a mile or so from home, I think registration was out, nothing serious.
State Trooper comes up, I reach for a wallet that isnt there. So here I am trying to prove who I am.
As he's running the plate against the info I'd given him it dawns on me - gun in car.
Concealed. It was in it's case in a small bag in the front floor boards. Along with my recently-completed CCP information...but no CCP yet, hadnt filed yet. I think, if I remember right, it'd only been a week since I'd taken the course.
So now my arm is waving out the window, trying to get his attention. He comes up, I keep my hands on the steering wheel and inform that there is a pistol in the car and, pretty much, run through this whole story right quick.
Pretty cool, he just asked exactly where it was, how it was stored etc, I explained, he retrieved until stop was over.
Told me to turn around, go get my ID, put my pistol away, and have a good day.
Nice guy that understood I simply had a brainfart and left my ID at home and had forgotten pistol in car due to the winter weather.
