I think the whole thing reminds me of hypes when people get killed by snakes.
It only happens once in a great while, and on the other hand dogs kill people about once a week. (I do have that statistic if anyone wants it).
But it was unintelligent move on the trainer and the park owners; since this animal has been involved in multiple deaths of other people, it should not be used to show, at all.
P.S. They're wild animals just like lions, tigers, and large constrictors, and should be treated as such and with the same respect. That's an important understanding of all keepers and trainers.
P.S.S. Orcas are not whales. Kinda bugs me. It's like calling a boa a python. Orcas are the largest species of the dolphin family.
