Internet filters give librarians control in order to protect children from harmful material. What’s the objection?
The U.S. Supreme Court has acknowledged that the protection of minors is a compelling government interest. But, the Court has also ruled that protecting minors does not mean that the government has carte blanche to suppress the free-speech rights of adults and older minors. The problem with filters is that they block too much legitimate, constitutionally protected material. A federal court had ruled that less-restrictive alternatives to filtering exist, so that speech is not banned in such a broad swath. The Supreme Court, however, overturned that ruling.
