Problem
1) Within a utilitarian framework, can the police be justified in arresting an innocent person to stop a major riot in which people are actively being harmed?
2) Why might a utilitarian say, yes, is it ok to commit an "injustice" such as punishing the wrong person deliberately?
3) How might a utilitarian argue that such a maneuver is really not such a good idea? What sort of consequences might unfold from arresting an innocent bystander?
