farmer's petrol tank had been regularly robbed by local youths in the early hours of the morning. The farmer had complained to the police, but the thefts continued. Deciding to take the law into his own hands, the farmer lay in wait to catch the thieves. A car drove up with its headlights out, and a person started to fill the tank. The farmer fired a shot to immobilise the car, but hit the passenger crouched on the front seat. Will the passenger be successful in a suit against the farmer in negligence?
