Spell it out then.
Life begins at conception. Behavior of a mother leading to miscarriage is manslaughter. I believe those were your words?
You said it, not me.
Provide a definition or manslaughter and murder. "common sense" doesn't hold water. Write the statute for us, counsel.
Okay.
Drug abuse causing miscarriage = manslaughter
Willful abortion = murder
Got it sport. You can build from there with common sense.
