San Fran Tiger Story - Taunting?

Those who know me, know I love animals. I really like big cats, but come on - they are wild animals. When I first heard of the San Fran story, I was shocked, but in the back of my mind wondered if something was fishy here. I mean, why did this animal get out and go crazy? I had my suspisions, now confirmed by THIS STORY. Not that I want to see people die, but come on - what do you expect when taunting a wild animal.
