Congressman Peter King (R-NY) has introduced a new law entitled the Camera Phone Predator Alert Act (H.R. 414). The proposed law would "require mobile phones containing digital cameras to make a sound when a photograph is taken." The Act makes the finding that "children and adolescents have been exploited by photographs taken in dressing rooms and public places with the use of a camera phone."
