Killer whale attack!!!!!

I am sure that everyone has seen the killer whale attack in orlando, I am not really shocked. This animal killed another person also, so why would someone think they would not again. Animals are wild and that is just it. No matter how much you train an animal, there is always a chance for it to turn to natural intincts. It was playing, that is just it, something weighing that much does not have to put much effort into accidently hurting or killing something as small as a human. I was attacked by a horse, not really attacked, it was playing around and I was knocked unconsious, leaving me with a missing tooth and black eye. I was riding my horse bareback in the pasture when the other horse decided to play with one i was on. He charged and jumped on my horse hiting me with his head and knocking me out. Luckily my horse did not move and kept me on her back until I gained consiousness again. We should never let ourselves deal with animals and be put in a position where if we are not paying attention, we can get hurt or lose our lives. I don't think the whale should be put to sleep but it was raised sheltered and not for the wild, so it could never be released. It needs to just be put on dispayed and cared for for the rest of its life. No more showes where someone would put themselves in potential harms way. What are your views on the subject?
