Here Wikipedia on the Capital Hill Autonomous Zone. That was the easiest way I could find to explain it. This was, basically, started by a bunch of marchers over the death of George Floyd. So far there have been only two shootings and one deadly. The people that live there are being constantly harassed and fear for their lives. The police cannot go there without danger, and they actually stopped an ambulance trying to save one of the shooting victims. My daughter, and a friend, bicycled there yesterday - they do not plan on going back. It is, apparently, a "olly olly oxen free" sort of place where the children get to act out and, pretty much, do what they damned please. Currently it seems their goal is to shoot one another. It covers a whole 6 blocks which includes one park. When its finally all over I have no idea what its going to cost to clean it up but its not gonna be cheap. There are also people that live there who are starting to sue Seattle. The Seattle mayor, just turned this area over to the marchers who, in turn, has turned it into pure chaos. Capitol Hill Autonomous Zone is, basically, what happens when nobody is really in charge but many that think they are in charge.
Eventually its gonna have to get shut down and cleaned up. I think the problem is doing that without killing people. Its a really great example of how to take a cause (BLM and justice) and turn it to mud, piss a LOT of people off, lose direction, and possibly get us all another 4 more years of Trump. It is, in other words, A shame......
They tried to start another one in Portland, Ore and were immediately shut down. The difference is that the Seattle mayor seems to spend a LOT of time wringing her hands whilst the Portland mayor didn't screw around.
I don't think there is much else to say about this one. You can google it and there are a LOT of replies. If nothing else it is somewhat educational.
