Still, I hope someone grows some brains and decides against more 'business as usual.' I've not run across any other fatalities with the other 50+ killer whales in captivity, so having 3 associated with a single specimen really should be a clue. Just because most dogs are man's best friend doesn't mean you give a pit bull pardon after pardon after it attacks and kills someone. Seems to me human life is what is being devalued here.
Domesticated dogs aren't expected to kill people. This Killer whale, OTOH, was simply exhibiting his instinctual behavior. The trainer clearly was cognizant of the dangers of her profession and assumed the liability in choosing to work with wild and potentially dangerous animals.
The whale can't be held culpable for acting like a killer whale.
