I also agree with this. It seems like in the majority of cases at this point, the curfew does nothing but create unnecessary conflict. It almost creates an objective for protesters - to be serious about what they're protesting, they need to stay out after the curfew.
I think curfews do have a place when there's massive looting happening and the police need the streets clear so they can prevent it, but there hasn't been enough looting in several days to justify curfews.
