Root cause analysis

A woman is suing an American company after being attacked by a legless female mannequin in one of its stores. The incident happened a year ago as the woman shopped for a blouse. The only one in her size was on the mannequin and as a sales assistant removed the garment, the dummy's arm flew off and hit the woman in the head. She was treated at the scene by paramedics - and later took herself to hospital. Injuries from the incident: bleeding scalp, cracked molar (requiring a root canal) and recurring shoulder pain.

Of course, in retrospect, it’s easy to see that this was an accident waiting to happen - obviously the mannequin was legless but it wasn't 'armless (well, initially, anyway).
