Fatal tiger attack

Horrible story and a parent's worst nightmare - an innocuous trip to the zoo turns deadly, on Christmas day no less. The first thing I thought was "BIG lawsuit," but now it sounds like the boys may have taunted the tiger or even helped it get out, though probably inadvertently (not surprisingly, they're not talking). The San Francisco zoo, and many others no doubt, will be installing security cameras. What a sad commentary. And of course this raises larger issues about keeping predators in cages and expecting them to suppress their natural instincts (when clearly they do not).
