Still, it is an extremely unlikely, rare case. How many children are killed by car accidents vs. gorillas in a zoo?

I don't know if this is true. We haven't tried a gorilla cage but my infant can clear half a flight of stairs in 5 seconds.

A) it wasn't an infant, it was a toddler. Toddlers can be pretty quick B) the fence was not substantial, a toddler could easily walk through it (and did); then there was a couple feet of ground until the slope down to the moat. C) the mom had more than one child there. D) it's not socially acceptable to put leashes on children (except for the cutesy backpack ones, but that's not really going to help)

The gorilla enclosure was built to prevent the gorilla from getting out, not to prevent people from getting in.

You have obviously never taken a toddler to a public place. Try taking a toddler to a zoo, park, childrens museum, just about any play area...and see how quickly they dash from one area to another. Having 2 toddlers, it's easy to have one child go in a direction and the second in another. Unless you have reasonable cause for neglect, it's easy to be at a zoo, look at an animal for 10 seconds, and then see your child is suddenly 10 feet away from you. Anyone who says "what a horrible parent" does not have children.

I managed to die in about 15 seconds, while my mom bent to fasten the shoe for my little sis. I was standing right in front of her and when she bent down I just made a few steps forward, that was enough.
