I knew the regulation 670-1 covered it, I just wanted some clarification from others if I was right or wrong. He hid his badge in his breast pocket, however the retracting cord and clip were visible outside his pocket, affixed to the flap. According to the AR he was wrong. When I tried to correct him, he said "show me in black and white". When I presented this to him, he said that the security badge was not on display and the clip was perfectly fine on display.
