I think you've demonstrated the issue, which is that we do tend to think there is the defence domain and there is the security and safety domain. What we're trying to say is that we need to bring these together. We cannot work in isolation anymore.
I would suggest you look at the Marine Security Operation Centres as the model. To help with the NORAD maritime warning function, members of the military, RCMP and Coast Guard, etc., share information. They use a common lexicon so they do not prejudice court cases, but then they have a common operating picture. All agencies and the military know what they're looking for. Then they can share things like surveillance time, which is very precious. It doesn't make sense to have DND looking for just one thing when they could also be looking for safety and security issues.
