Wow... Mostly speechless. How sadistic. If they can't hold the child responsible, I surely hope they go after compensation from the parents. Also how sad things are if this happened the other way too. Like if the zoo had barbed wire on the top of the fence, and they found that little hell-raiser stuck up there, how this would so quickly turn into the "zoo's fault" and they are to be held responsible.
Question though, by 7 or 8, I was pretty aware that I would be held accountable for my actions, and the main reason I didn't do stuff was because of the following consequences that would occur. So if children under 10, can't be held responsible for criminal actions, how in the world do they keep them under control down there? Throwing rocks at cars on the freeway, graffiti pretty much anything, etc, etc?
