I like to think that I don't live in a country ruled by a King but rather in a community of citizens who have collectively agreed on a way of doing things. This includes the right to express dissent against other citizens to whom we have delegated certain decision-making responsibilities. A permit isn't about seeking permission; it's about ensuring an orderly process so that things don't devolve into chaos and bouncy castles.
At the time, I think we were also in stage 2 lockdown(which should have been enough to stop it), so the people bearing the brunt of these actions, whatever you want to label it as, were not the ones making those decisions. Our elected officials don't live inside Parliament Hill.
