The detector has stopped detecting and started holding the room up badly. Its trays are jammed sideways, the chair has climbed the wall rather than seat anyone, and the queue barrier enters at shin height because courtesy was always structural theatre. The yellow rail does the actual bracing. Orange straps, ugly plates and tired bolts keep every force visible. Security has not failed here. It has been emptied of purpose and left blocking the people it was built to sort.
