NPR's Larry Abramson reports the library system in Loudoun County, Virgina is facing a court mandate to drop its internet filtering policy. Civillibertarians say Virginia's filtering system blocks people's right to freespeech. Supporters of the system agree it may not be perfect but say they havea responsibility to protect children from pornography. So far, Loundoun Countyis the only system facing legal action. Other libraries are watching to seehow they can better equip their libraries and avoid similar problems.
