Mike Tyson and how to balance childhood safety

I have been posting away about the wisdom of the Free-Range Movement and how healthy it is to be less overbearing about safety. I have been working on being less of a helicopter parent and more of a relaxed parent, allowing my kids more freedom to explore the world. And then I read about Mike Tyson's tragedy with his 4-year-old baby...and I am right back where I started. How do parents strike the balance?
