The article states laconically that “Seattle police are still responding to 911 calls in the area.” Have they sent officers into the area on regular business with no trouble? By regular business, I mean that a call that would’ve gotten two officers normally gets that now, not having to send in a squad of officers in riot gear just to answer a burglary call.
What does “only residents are allowed in” mean? By the protesters or the police?
Can fire engines and ambulances respond to calls? Is the mail being delivered and picked up regularly? Are the utilities operating, and can utility crews work in the area? Is trash & recycling being picked up?
If there’s no significant threat to people or property, and the answers to my first question and my last set of questions are all “yes”, I don’t see what there is to do, other than negotiation or discussion, so long as those circumstances continue. IMHO, it would be a waste of resources and an unnecessary escalation to impose authority merely for the sake of imposing it.
