RJ:
The motto can be translated from the Latin as, "No one attacks me with impunity." It is of Scottish origin and is said to have first appeared on the coins of James VI of Scotland (James I of England). It was emblazoned on the flag of the Richmond Rifle Rangers in the American Revolutionary War, is used today by some British military units, and is the motto of the Order of the Thistle. It is also often associated with Police Memorial Day in the United States.

It is also the motto of the Montresor family in Poe's The Cask of Amontillado:
Here I knocked off the neck of a bottle which I drew from a long row of its fellows that lay upon the mould.
"Drink," I said, presenting him the wine.
He raised it to his lips with a leer. He paused and nodded to me familiarly, while his bells jingled.
"I drink," he said, "to the buried that repose around us."
"And I to your long life."
He again took my arm and we proceeded.
"These vaults," he said, are extensive."
"The Montresors," I replied, "were a great numerous family."
"I forget your arms."
"A huge human foot d'or, in a field azure; the foot crushes a serpent rampant whose fangs are imbedded in the heel."
"And the motto?"
"Nemo me impune lacessit."
"Good!" he said.
Ya gotta love Poe
