Yes, that's the point: enforcement practices have changed from what I thought to be the case.
A CBC article includes this: "It came to this, largely, because this is the way that police agencies have been moving for the last 10 years," he said. "A strategy of containment and hoping the protests fizzle out enough that they can then be dealt with. So this has been very textbook."
So my thinking was old-school. Obviously we can't have distinct standards based on skin colour or political or religious affiliations. So I suppose the next question is, how do people want authorities to respond to civil disobedience now that we've had a taste of it from all across the political spectrum these past couple of years, plus examples from other countries?
