Are you not aware of Conners law? That was passed by Congress and signed by Bush. It states that a fetus is a child (ie human being) from the time of conception. It makes killing a fetus (a child in the womb) a crime. Scott Peterson was convicted of double homicide.
No, I knew that many states had laws allowing murder prosecutions like that though. Obviously, though, the laws must be written to be useless in terms of challenging abortion statutes, or this wouldn’t be an issue.
