I think you underestimate how salty the protesters are, and how limp-wristed the mayor is. I'd bet my next paycheck the BLM faction will swarm in as soon as the cops move the line, establish a new zone that doesn't include the police precinct, and keep up an annoying protest against the building itself.
The difference will be in its cohesion. Antifa established the original zone, but they've been kicked out. Warlord Raz and the JBGC ran security, but they're hiding after they executed those two teenage black boys. The militant factions are either gone or scared, and in the last 4 days I've only seen BLM, residents, and gawkers in the area or protesting on the line. And they're already parroting the predictable talking point: "CHOP isn't an
area, it's an
idea".
So the new zone will be a pathetic drawn out protest, to save face. They
have to claim they're still defying the city, because they didn't get their big demands met. So they'll probably just set up a handful of tents, form a line outside the precinct building, and keep things up until the cops get another excuse to sweep in and clear them out.
The variables here are the cops' willingness to fight, and the July 4th weekend. Morale in SPD is low, but they did just get a "victory" by taking the precinct back. If the cops become more willing to push out any tent city as soon as they spring up, CHAZ 2.0 will dissolve fast. All they'd need for cover is an order from the mayor, "no temporary structures may be put up for more than 24 hours".
But a long weekend starts tomorrow (people get Friday off since the holiday is on Saturday). People will have more time to go down and protest, it will be very hot, and fireworks will be in play. People still want to protest, and now they'll have more free time to do it, right when the objects of their hatred are standing in the open, "occupying" a symbolic place.
TL;DR Keep an eye on Seattle this weekend. It may be the perfect storm for another big street fight. The fate of CHAZ 2.0 will be decided by Monday.
