What else could they have done at that point but to take the gorilla down? It was unfortunate that the gorilla had to die, but a kid is a kid.
Now the police are investigating the parents to see if there's a way that they can charge them with anything so they can make some money off of it.
It's easy to sit in an easy chair and denigrate the parents, as if they weren't watching the boy, but anyone who has ever raised kids can attest to... the little buggers are fast and mischevious. This still could have happened even with supervision.
Like I said, just an unfortunate incident.
The only ones really looking bad over this, are those who cry for the gorilla, as if it was more valuable than the child.
