The Fort Vancouver Regional Library District in So WA which has libraries in four counties refused to filter all computers for years until the voters got to them through their pocketbooks.
A few years ago we voted down a bond measure twice and it finally got their attention. All computers are filtered for adults and children now and the bond measure was passed. The ACLU and the ALA can go pound sand on their lawsuits, SCOTUS has ruled that filtering is permissable.
