Wow! That is incredibly stupid. When it comes to the predictability of animals, and more so reptiles which aren't known for having complex thinking, it's like playing Russian roulette. Just ask Roy how predictable animals are? Or ask the family of the guy that used to live with the bears? You only get one chance to be wrong when it comes to these creatures. She and her family are lucky this time wasn't it.
Oh and one more thing. Here is irrefutable evidence that a college degree doesn't equate to intelligence and if I were the zoo, I wouldn't hire her for fear of liability.
