Personally, I wouldn't be in favor of classifying that as a homicide, but would rather it be an aggravating factor attached to the crime of shooting the actual person.

There is a cost, morally and emotionally, to a fetus dying, but it's not a crime against the fetus but the mother.

The existence of a law written in a way I disagree with doesn't obligate me to agree with another one I disagree with.
