If it was involving the suspected terrorist currently on trial in LA the raid you saw took place in Montreal. My guess, is that the jackets come in either English, French, or both

That's what I figured, except that the raid, almost six months ago now, was definitely in Ottawa. I never got to see the fronts of the jackets, which undoubtedly had the delightfully bilingual "police" on them, but I guess that you don't want people having to stop and decipher two sets of letters on somebody's jacket in the middle of a crisis situation!
