Order

Latin ordo — row, arrangement, rank. From Proto-Indo-European roots meaning to put in order. Military rank, religious orders, social hierarchy, and the injunction to 'restore order' all descend from the same root: arrangement by rank.

'Law and order' as a political phrase dates to the Nixon era and has been reliably deployed since to signal tough-on-crime politics. 'Order' implies there was order before, that disorder is an intrusion, and that restoration is the goal — all contestable assumptions.
