Still say, cut the power and water, enforce the blockade preventing anyone to enter / re-enter. When they come out, arrest them and prosecute them.
But, this is Seattle, so they will wring their hands and let CRAP wallow in their filth, drugs, and violence. Let them shoot get other and don’t worry about it.
Exactly what I’ve said from day 1.
Surround with overwhelming military.
Shut off all utilities and phone.
Nobody in, nobody out.
As they try to leave, arrest every damn one of them. Posted that first day I think. Still think so.
Let the National Guard drive up on each of the streets that cross into the zone and emplace MUMVEEs with machine guns on them, Then move in infantry with M-16s and make obvious preparations to move in. Announce over bullhorns and on TV that there will be one open street for exit, open for 4 hours. Then all units move into the zone ahead of the police who are empowered to arrest and hold anyone they meet.
