GRC = Gendarmerie royale du Canada

Merci. One thing that struck my mischievous mind was why the jackets of the Mounties in question did not follow the usual slavishly ubiqituous devotion to bilingualism I have come to expect of things Canadian. The jackets only had GRC on them, not RCMP, and the police in question were in Ottawa. Enlightenment, s'il vous plait?
