Two virtual cigars and a tip of the hat to Charlene for getting the answer right: Our research has shown that 1970 is the likely date that the “Lex et Ordo” phrase was incorporated into the insignia. However, we were unable to confirm that with the Police Department. We have found very few other instances of the phrase in continued use on police insignias, and regard Traverse City’s as a historical relic.

Well done, Charlene!
