Cops lives are nothing special. Maybe if you kill a child or a pregnant woman you should get extra jail time but, not a cop. Women, in general, do not die because of unwanted pregnancy. They are inconvenienced by unwanted pregnancy. If they have an abortion the inconvenience is only one of a few days.
Adoption is a viable alternative to abortion.
Thus the only real question is can a woman afford to give up 6-9 months of her life to avoid resorting to murder. Well, you know, it's actually very simple. You see, women live like 5 years longer than men. They've got the spare time. It would take 7-10 unwanted pregnancies and adoptions to force a woman to sacrifice so many years of her life that she would only have as much left over as men have in the first place.
