We all knew it was just a short term political show to get the Feds to drop their defenses.
OSP was not part of the leftist political game there. The state police have to respond when requested and they did. This is a pretty big blow to Portland because the troopers were far more effective than Portland PD who have been totally neutered.
Now you have a decreased Fed presence, no state police, and emboldened anarchists who know they face little chance of consequences.
It will get worse now and the anarchists have already started moving out of the city center.
