The legalities for this gets interesting. In most jurisdictions it's perfectly legal to film a crime, but trying to profit off the footage without a model release is illegal. Which means sticking the video on some kind of sharing platform is fine, but trying to monetize it on Youtube or selling the footage to a distributor of some sort would be illegal without a signed release from the subjects in the video.
Getting back on topic, I'm not surprised. Toronto is my city and our local and Provincial leaders have badly bungled everything from the beginning. People have reached their breaking point and shit's starting to get ugly. I work part time in retail and we've seen some potentially ugly incidents. It's only going to get worse from here.
