Answer: None. Throw the doctor in jail for 2 years.
Yeah, that’s what I was thinking too. The woman has to live with herself for the rest of her life, the doctor gets whatever a murder charge carries in that state. That will dry up the supply of people who will do abortions pretty quickly.
You are willing to let an accomplice in a premeditated murder walk free?
The problem there is that you don't need a doctor to perform an abortion. For example in my state (IL) the last few yeas before abortions became illegal there were a were a number of womens' groups teaching how to perform “menstrual extractions”.
The only time a doctor needs become involved in a first trimester abortion is the unusual case where something goes wrong, in which case they are treated the complications of a botched abortion.
