Arthur owns a property with a large back yard that is usually lit at night by bright floodlights. For months he has been asking local teenagers to stop using his yard as a 'short-cut' to the bus stop, but they continue to ignore him.

Arthur decides to install an in-ground swimming pool. Last Saturday night, after the pool contractor has spent the day excavating a large hole, Arthur decided not to switch on the floodlights. At 11 pm, one of the teenagers, Gerry, fell into the hole and suffered serious injuries.
