Here's hoping it sustains itself for a while.
I'm not passing judgment yet since the days are young and the political bias on the ground is thick in both directions. But it is definitely not "by all accounts".
But my personal bias on the table is that yeah, trading police that were imperfectly constrained by the system for new police utterly and entirely unconstrained by the system is probably not going to go well. The real "fun" will start when Raz's faction pisses off enough people to form a violent counterfaction and you get a gang war, so give it a bit. It takes time for these things to develop. Let the honeymoon wear off and have this place showing a functioning system for, oh, say, at least a month before declaring victory. Not that you declared victory, I'm just saying, I recommend against getting too invested in this.
It's not as if "a place that has no police" is some shocking new experiment that has never been run before; you've got plenty of places you can look out in the world to see what happens next. It's not a difficult-to-predict progression.
Aside, intentionally or unintentionally, calling a group of predominantly black people "thugs" is a common dog whistle.
That was just the beginning of the confrontation. If you watch the full video the group then followed and hassled the tagger for several minutes before the tagger was hit in the face and had their glasses broken (and their smartphone was stolen from them). Someone also threatened to blow the taggers brains out.
