From Engadget:
New York Representative Pete King is hoping that the US will soon have a law requiring that all cameraphones make a noise when they snap a picture as well. To that end, King has re-introduced the so-called “Camera Phone Predator Alert Act,” which was actually first introduced in 2007 but went nowhere at the time. The bill, as the name not-so-subtly suggests, aims to prevent folks from taking cameraphone pictures without others people’s knowledge by forcing the phones to make a sound that’s “audible within a reasonable radius” and not able to be disabled.

a recent survey of over a thousand teenagers and young adults (13 through 26) revealed that a fifth of the teens queried have posted a digital photo or video of themselves in their complete or partial birthday suits on the Internet. A third of the latter group have done the same.
