We shouldn't be surprised that a few idiots impede traffic, break a window, or overturn a car. One does not encourage or excuse such acts by anticipating them and planning restraint; a few louts in a crowd do not justify sweeping or pre-emptive arrests.
Let me also say that there will be peaceful protesters who will worry about this legislation being used to facilitate the use of facial identification technology, not just to catalogue criminal acts—things that are already criminal under the Criminal Code—but also to track participation in political protests and the expression of dissent.
I worry that if it becomes law, this legislation will seek to deter important acts of political expression. That is something that I think all the members of this committee should consider carefully.
