Freak accidents

As usual, I've been listening to the radio, and I've heard quite a bit about the airplane that slid off the runway in Chicago and killed a kid. Now a bunch of activists are demanding that airports implement "buffer zones" so that something like this won't ever happen again. Ok, I know that it's unfortunate that this kid died and that this whole thing happened, but it was a freak accident. They happen. If you tried to act on every freak accident so that it never happens again, the world would just be insane!
