Look up the police department motto in a city where you used to live and report back.
I'm wondering how many alternatives to “To serve and protect” there are.
Simply finding the department's home page should do it.
For instance, St. Louis goes with “Service, Integrity, Leadership and Fair Treatment To All.”
The police department in Erie, Pennsylvania, opts for “To protect and serve.”
In Flagstaff, Arizona, it's “Service at a Higher Elevation.”
In Sault Ste. Marie, Ontario, it's “Committed to Excellence in Our Commiunity.”
There must have been some issues in Binghamton, N.Y. That department's motto is “Restoring the Pride.”
But self-esteem appears to be in good supply in Cheyenne, Wyoming, where the police slogan is “Protecting the Legend.”
