Just another emotional response. Someone dies so someone has to be punished for it. Sorry. No can do. Accidents are just that. Every accident is rooted in some negligence because by definition all accidents can be prevented. But holding people legally responsible and seeking to punish them is unacceptable. What if the kid fell out of the tree house?
If an individual's death is due directly to another's negligence, the negligent individual should be punished. It isn't an emotional response, but a logical one.
If a kid falls out of a tree house, it depends upon whose negligence caused the accident.
