A woman was allegedly raped on a suburban Philadelphia train last week while police said there were "a lot of people" around who "should have done something."
Must bystanders do anything if they witness an ongoing rape in Pennsylvania, United States?

There is no all-encompassing legal obligation in the United States that a bystander who sees an act of violence must intervene or call police. But there are exceptions to that idea, dubbed the no-duty rule. Many states have laws requiring intervention when the victim of an ongoing attack is a child. The relationship of the witness to the victim is also a factor in assessing criminal or civil liability: Bosses may have a duty to intervene on behalf of employees, teachers for students and spouses for spouses.
