"The flood of Webcams and their use by young people has created a law enforcement challenge, officials said, impeding efforts to find predators online. In the old days, police and federal agents would pose online as teenagers and arrest the adults who attempted to entice them into sexual situations. But now, law enforcement officials involved in such online impersonations said, it is common for an adult to demand that a teenager turn on a Webcam after the first few minutes of conversation. Police cannot use real children to lure wrongdoers, and they cannot broadcast underage pornographic images. That has left law enforcement officials having to make excuses for why they do not have a Webcam."
