If you can’t mark the point at which there is a bright line between “no human life” and “human life”,
killing that life is gross criminal negligence.
There are those that claim the USSC has defined this bright line at 3 months. I’ve actually heard someone argue this - that one day prior, it is not a human life, and one day after it is. (Yet they didn’t support outlawing partial birth abortion - go figure)
Should a doctor report an apparent miscarraige to the police to be investigated as a possible homicide?
