What do you think about Shamu, the killer whales, and the occurrence of injuries and deaths?

I’ve been hearing a lot about Shamu, killer whales, and the people they’ve killed. It’s on tv, the internet, etc. I was wondering, do you think it’s safe for these trainers to swim with whales, that have good potential, but hurt human beings by nature and instincts? I see that Shamu is a great example for young kids when they learn about whales, or sea life. Shamu is a sweet whale, but do you think that for the future, we should still be able to swim with these “killer“whales?
