I blame my parents. Because they weren't "helecoptoring" and watching me every second of every day, an innocent dog had to be put down. Had they been watching me as I sold chocolate bars for Little League, they would have prevented me from walking into a garage where a man was working on his car with his doberman chained beside him. Unfortunately, because my neglectful parents weren't around and because the man had his back to me and didn't notice what I was about to do, I entered the garage and the guard-trained dog sought to "protect" its master and ended up biting me, and for that they ended up putting the dog down.
Seriously, this has been taken way out of proportion. Yes, maybe the mom could have paid more attention to her children, but then again there hasn't been a parent alive that hasn't paid constant attention to a kid, and the kid ends up getting hurt. Parents are always bemoaning the fact that they turned their back for 1 second, and their little one goes running off somewhere. And yes, maybe the zoo could have built better enclosures to prevent people from accidentally entering an animal exhibit, but again they've had so many visitors prior to this without something like this happening, so it appears that the zoo had thought their enclosures were pretty impenetrable esp. for their average visitor.
It was a terrible accident. It is sad that an animal had to die in order to protect a human. But when you consider the number of people killed this weekend alone, this story pales in comparison as something important and newsworthy.
