I think the laws should be different when comes aborting fetuses at are already dead, as opposed to fetuses that are still alive. I don’t think there needs to be any restrictions put on aborting dead fetuses.
That’s why a viability standard makes more sense than an arbitrary number of weeks–it’s medically flexible enough to cover a lot of scenarios (but still not all). Also, the life of the mother is a very serious consideration that’s far too frequently left out of the equation because people can be real shits.
