“my question is: can murdering doctors and mothers be brought to justice? “
Punitive laws can’t be made retroactive, and no one is arguing for that.
We have thousands of cases of mass murders and crimes against humanity. If the unborn are persons and MILLIONS of persons have died at the direct hand of their killers, should there be no responsibility to go around?
Ex post facto laws are specifically prohibited by the Constitution. And for me this has always been about stopping the butchery, not exacting vengeance.
