The US Supreme Court has ruled that Congress can force public libraries to install and use porn filters on library computers. “Congress passed the law, the Children’s Internet Protection Act, in 2000, but it did not take effect pending the legal challenge by public libraries and civil liberties groups, which argued that any filter also inadvertently blocks access to other, noncontroversial sites, as some studies have shown. But in a 6-3 ruling, the court said the law did not violate the First Amendment guaranteeing free speech because libraries will have the capability to disable the filters for any adult patron who may ask.”
