Absolutely. We see it on Parliament Hill all the time.
In fact, when the Ottawa police, working in conjunction with a number of other police forces, cleared Wellington Street, the protesters set up legally on sidewalks further down the street and nobody bothered them. They were allowed to make their point. That's legitimate free speech. That's legitimate protest.
That's not what the situation on Wellington Street was or on the Ambassador Bridge or in Coutts, Alberta.
