I think it's best to maintain the Non-Violence Protest approach. More people are likely to come to your side with it, and if something does break, it's good to remind ourselves that heroes usually sprout from humble beginnings. We've already seen that this protest was planned well in advance, showing there is strong leadership amongst the people, and the peace and hope it's brought is way more infectious than BurnMurderLooting. The doomposting can wait.
Like it's been said, it's best to spend a night reading up on your Rights as a Canadian and to maintain a mindset of standing strong in the face of tyranny. Keep laughing, keep honking, and remember that this has shown a wellspring of support across the nation. You're not alone in wanting this to end, as shown in this thread, and I'm sure the police can't monitor every street in Ottawa. Fuel will flow, as will provisions and 1550 Polish Sausages.
