I don't believe the gorilla meant any harm to the child but it had no way of knowing that a human baby can't be slung around as it would a young ape.I think even a chimpanzee is probably stronger than a grown man....as for the parents,if course no one can speak for them but they were probably just distracted in watching the animals.....but that is no excuse.I wish there had been a better solution, but even though Silver Back may have been protecting the 4yr. old the gorilla could easily kill the child without knowing it because of the Silver Back's strength. Gorilla 's are my favorite of the primate family. They were need to investigate the parents, and find out where and what they doing at the time the child ended up in the enclosure.
