To all freepers who do not believe the zoo is at fault:
If the tiger had mauled and killed an innocent family, you all would be singing a different tune.
I don’t think it’s as simple or straightforward as you make it out to be.
Suppose I have a 9 year old guard dog with signs posted: Keep Out and Beware of Dog. The dog is trained and has never left the yard. He’s only hurt one person. A few years ago he bit a small child who unwittingly pushed him and grabbed his food bowl while he was eating. The child recovered OK and, since this was the only bad incident, we didn’t euthanize the dog.
Now suppose some young men, perhaps drunk, stand outside my fence, in the dark, with a slingshot. They begin taunting the dog and pelting him with rocks. Some hit the dog, some hit the house. The dog becomes more and more agitated, snarling viciously at them through the fence. But they take no heed and continue yelling and pelting him.
So. If the dog jumps the fence and attacks them, who is at fault? Obviously, I would second guess my decision not to put the dog away earlier. But, really, what kind of idiot slings rocks at a viciously provoked animal? I would blame them more than myself.
The tigers had all been content and fine in that pit for 67 years. It took motivation for that tiger to jump out, and the punks with slingshots provided the motivation. Had it been my kid, I wouldn't blame anyone else, but my own kid.
I'd expect the zoo to dig a deeper pit, and nothing else. When you taunt and torment animals in a cage, or on a chain and they break loose and bite you, it's 100% your own damn fault.
