If I was a cop I think I would have them leave it be. Or if its out ask them to clear it perhaps? Our ccw teacher said he always appreciates it when someone informs him they are carrying. No surprises makes everyone safer.

I would inform I think, especially if Im carrying on my hip. If you reach for your bill fold and his parter sees a gun on your hip... I would rather not have 40 sw bullet rattling around in my cranium.

Dads friend (ya one of those stories : p ) Said a state trooper almost put one in his head one day. Hes also law enforcement and was carrying a gun in his breifcase... with his ID... and forgot it was there. He reached over flipped the top up and heard a "Dont you Fing move" and had a gun to the side of his head.
