Teacher who survived polar bear mauling at zoo 'was depressed over job':

Rifles had already been issued to marksmen and Heiner Kloes, a zoo spokesman, said: "This woman's behaviour not only put her life in danger but also that of the staff who had to rescue her. "However, we do have guns and we would have been prepared to use them without hesitation if it was felt it was the only way to save the woman." ... On Monday it emerged that she is a teacher who had been driven to despair by her failure to find a job.
