"Over the last year, the American Civil Liberties Union has asked officials from hundreds of school districts around the country to make changes in their Internet screening systems to eliminate bias, said Anthony Rothert, a civil liberties lawyer based in St. Louis.
All have agreed to, he said, except Camdenton, which the A.C.L.U. sued last summer.
The lawsuit — believed to be the first of its kind — does not claim that this rural district of 4,200 students purchased the software with the intent of discriminating. Rather, it says, once there were complaints about the filter last year, school officials refused to replace it. An investigator for the A.C.L.U. has been able to figure out how the filter works, but not who developed it.
… Judge Laughrey noted that the URLBlacklist filter was even bad at doing its primary, legal job: blocking pornography. Tested on its ability to recognize 500 sexually explicit sites, it missed 30 percent of them. CIPAFilter, one of the leaders in the field, missed 3 percent.”
