I heard this story on the radio yesterday. A woman caught her boyfriend in flagrante with another woman in the back of a BMW. She was so enraged by this that she took a baseball bat to the car, wrecking the lights, windows and sunroof etc. The understandably alarmed occupants called the police who arrived and apart from stopping her doing what she was doing, took no action against her whatsover as no crime had been committed. Why? Because in her anger it slipped her mind that the car was hers.
