alt Hacker NewsI'm sorry but no, you should not get life in prison if your dog kills your baby without warning. In that horrible scenario, it's punishment enough that you've lost your baby and that your dog did it (and consequently you've also lost your dog). Not every tragedy is a human's fault.
Your reply only makes sense if we see the baby as property. If we see the baby as a full human who died because of another human's negligence, then suddenly the scenario becomes a lot more complicated.
Not life in prison complicated, but probably more than "he's been punished enough." complicated.
