Horrible: Boy Mauled at Zoo - Can you Shoot?
As a father to be who seems to feel more ferociously protective by the day (at 7 months along) yes I would have intervened, as others have said even if that meant going into the pit myself.
The other sad part, to me, is they were just discussing on the news what they should do to the animals themselves. This is beyond horrible, I can't even imagine it, but the wild dogs did what wild dogs do, it wasn't a planned strike against humankind. There's a reason when we visit zoos that the animals are barricaded in rather than walking among us.
