It is certainly very gruesome and profoundly sad, but I'm not sure it stands the test of malice. I think if I were in charge, abortion would be considered manslaughter. Far more for the doctor than the mother, because he does it just to turn a profit. I presume nearly all women who do it do so because they feel that they have no other choice. Maybe the doctor saw obgyn as his only real choice given his talents.
LAw ought to be consistent and based on the action.
Murder is already illegal and, if the laws regulating abortion conflict, then the courts will have to sort it out. All you need is a judge who will apply existing law to the 'murder' of a 'pre-born' person. Simple and legal. If you are not prepared to treat abortion as 'murder' then stop calling it that. It is certainly very gruesome and profoundly sad, but I'm not sure it stands the test of malice.
