I think that might explain it. 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. Since in any case they would have POLICE (a bilingual word) on them as well so it probably isn't an issue.

In the same way, the Canadian Forces jackets have either Canadian Forces or Forces canadiennes but not both.

Since you mentioned bilingual, the government used a rather smart workaround to make its web addresses bilingual. It seems most US government addresses are something.gov. In Canada the homepage is www.gc.ca. Perfectly bilingual: Government of Canada or Gouvernement du Canada.
