CNET reports US Rep. Pete King introduced a bill in the House of Representatives to ban camera phones from having a silent mode when taking a picture. The bill is named the "Camera Phone Predator Alert Act", King argues the ban is necessary to prevent exploitation:
The Camera Phone Predator Alert Act (H.R. 414) would "require any mobile phone containing a digital camera to sound a tone whenever a photograph is taken." What's more, the bill would prohibit such handsets from being equipped with a means of disabling or silencing the tone. Enforcement would be through the Consumer Product Safety Commission.
The text of the bill is short and King's office has not released any public statements. Yet, the reasoning behind the legislation is clear. The text states that "Congress finds that children and adolescents have been exploited by photographs taken in dressing rooms and public places with the use of a camera phone."
