That’s correct, and then even above and beyond that the RCMP are very averse to give basically any useful at all.You're making an assumption that there is a difference. Not saying that it is the case here, but the media can make assumptions, speculations, draw straight line where they don't exist - the police cannot.
If the BC system is anything like Ontario, once the civilian investigative agency has invoked its mandate, the police are extremely limited as to what they can say.
IMHO, Calgary sets a very high standard for public engagement on stuff like this. I’ve seen some excellent pressers out of Winnipeg as well.
