Hidden-camera shows have been a staple of television since the early days of the medium. Some, such as "Candid Camera," played the format for its comedic value. "What Would You Do?" takes it in a different, more serious, direction. The show sets up real-life situations involving actors (usually in danger or in need of help) to see if people will stop to help the actors or if they will mind their own business while passing right by the actors in the scene. ABC News correspondent John Quinones reports on how people react in the situations.
