Five people are tied up on the tram tracks...and there’s a tram heading straight for them!

So you either actively choose to kill one person, or passively allow five people to be killed. What do you do?
The Oxford Times recently ran a story about a cyclist who became trapped under a car. A group of passers-by managed to lift the car off her before the paramedics arrived and are rightly praised in the article for their heroic actions.
