Totally random, but spent a summer on OJT on loan to the cadet program in Whitehorse filling in for a CIC. We had a 12 gauge with slugs when we were out in the bush in case we ran into a bear.
That seemed like overkill until I saw how big the bears were, and how thick the bush is, and can absolutely see stumbling into a bear at close range. I think something like that would be completely reasonable for RCMP in remote communities for animal control situations without having to go to some kind of 'scary tactical longarm'. Plus if you miss it's not going to go another 500 yards, which seems generally useful in a policing situation if you are around a town.
Don't see why a 12 gauge with slugs and a C7 for a carbine wouldn't be a reasonable all purpose combo for a patrol car, as that way you get stopping power if you need it for something like a bear (or engine block I guess) and a C7 for longer range and accuracy for a mass shooting type situation.
