On February 24th a killer whale named Tilikum killed a Sea World whale trainer. The whale grabbed Dawn Brancheau, a longtime employee at Sea World, by her pony-tail and dragged her under the water. The whale kept her in his grasp for up to thirty minutes. Tilikum is a thirty year old killer whale and has a history of violence against trainers. The employees at Sea World and were instructed to not be in the water with Tilikum. Evidently, they should have taken more precautions when working with this particular whale.
This is no rarity that a wild animal who is held in captivity attacks a person. This brings up the question, should large animals be kept in captivity and be trained to perform in shows? Tilikum is not the only example of animals who perform in shows attack their trainer. In addition to killer whales, tigers or other large jungle cats have attacked people on stage while performing in magic shows or circuses. Animals attacking their trainers seems to be a growing problem. I believe these animals should not be forced to perform in front of crowds but instead should be slowly released back into the wild once they have gained the ability to survive in the wild.
