After a good while of uneventful partying and chilling, the local PD showed up and made things miserable for everybody. Started with a single tear gas round that (allegedly) came from a police vehicle which then sped away. Soon after, the riot police showed up, all geared up for the apocalypse. They formed a line and demanded that everyone disperse or there would be arrests "and/or other actions" taken.
People didn't take to this so well, and they started getting angry and loud. That's where the stream picks up.
There were (allegedly) some out-of-towners there who had it in mind to start a ruckus so they could get to looting, and they seized this opportunity to start. The looting happened for a pretty tense 5-10 minutes, followed shortly by protesters lining up to block the entrance to the storefronts. There's some interviews with them in the stream.
Things wound down after that, AFAIK.
