I say it depends on the circumstances. When I was at a small community college several years back, a deputy US Marshall came to my office to ask a few questions about someone there at the college. After we were finished talking, he stood up to leave and as he was going out the door of my office, I noticed his shirt had ridden up over the grip of his pistol; exposing the fact he was armed. I told him so; he thanked me, pulled the shirt back down, and that was that. Why was this particular circumstance the right time? Because people in civilian clothing in college buildings are not supposed to be carrying is why. If he had been made by anyone, either an "event" might have happened, or it was possible that his cover would have been blown. No one needed to know he was a Federal LEO; he if had wanted that known, he would not have come in old jeans and a casual t-shirt. In the case of what GED did, I wasn't there to evaluate the circumstances, and neither was anyone else here, but I think he is sufficiently experienced to make the call to tell or not, so I say he was okay in doing what he did.
