In Seinfeld: The Finale (#9.22) the four observe a robbery and do nothing. They are arrested for violating a Good Samaritan Law.Good Samaritan Laws are often confused with a duty to rescue. In the U.S., there is generally no duty to rescue. Good Samaritan Laws refer, instead, to "protecting from blame those who choose to aid others who are injured or ill. They are intended to reduce bystanders' hesitation to assist, for fear of being sued or prosecuted for unintentional injury."http://en.wikipedia.org/wiki/Good_Samaritan_lawhttp://en.wikipedia.org/wiki/Duty_to_rescueThe gang is arrested in Massachusetts - see Massachusetts exception in Duty to Rescue link. This law creates a duty to report, but not a duty to aid. Chapter 268, section 40 provides "Whoever knows that another person is a victim of aggravated rape, murder, manslaughter or armed robbery and is at the scene of said crime shall, to the extent that said person can do so without danger or peril to himself or others, report said crime to an appropriate law enforcement official as soon as reasonably practicable." "These laws are also referred to as Good Samaritan laws, despite their difference from laws of the same name that protect individuals that try to help another person. These laws are rarely applied, and are generally ignored by citizens and lawmakers." --Wikipedia.Larry David said, on the Season 9 DVD featurette "The Last Lap," that the germ of the idea for the Finale came from a law he heard about in France. Clearly, the philosophical and legal concepts of a duty to rescue someone to whom you have no special relationship vary around the world. This is a very interesting area of philosophy and law; however, the Finale does not portray an accurate representation of U.S. law, in particular because a police officer was on the scene the entire time.
