I think some of you are missing the forest through the trees. The question being posed here is: If we are going to argue that a fetus is a human, then why don't all laws/norms then apply to that human? The example given makes sense. If an infant dies in his or her parent's care, it will generally be investigated as to whether the parents were neglectful. If a miscarriage takes place, and we define the fetus as human, why don't we apply the same rules? Shouldn't the mother, at the very least, be forced to to take a blood alcohol test? If she is positive, should she be then charged with murder?
