To catch a predator shows us the investigations carried out using the hidden camera from Dateline NBC.

To Catch a Predator is an American reality television series that features hidden camera investigations by the television news magazine program Dateline NBC. It was devoted to impersonating underage people (generally ages 12 - 15) and detaining male adults who contacted them over the Internet for sexual liaisons. People were lured to meet with a decoy under the pretense of sexual contact and then confronted. Show host Chris Hansen clarified in an interview with NPR News that these subjects should be labeled as potential sexual predators, and not pedophiles. "Pedophiles have a very specific definition, people who are interested in prepubescent sex," he stated.—NBC
