You're kidding, right? When did you become a cavilling lawyer?
No. The same interpretation of the constitution that says abortion is an unjust allowance of a deprivation of human life without due process would necessarily also apply to perceived self-defense, because individual citizens are not judge, jury, and executioner.
The law is not morality. Don't confuse the two. It doesn't mean morality should not shape the law, but the law is not morality.
I am all in favor of using the power of the law to end abortion. Were I a mayor, for example, I would use the local Dept. of Licenses and Inspections to shutdown and bulldoze every abortion clinic in the city limits as a menace to human health and the safety of the residents of the city. I would order local abortionists arrested for murder charges and thrown them in jail without bail. I would work for zoning changes to forbid abortion clinics within the city limits.
But I am not in favor of further misinterpreting the constitution.
The fact is, pro-lifers are far too focused on bad solutions to the abortion problem like judicial activism, and totally remiss in using the powers they have at hand to address the problem.
There is also a political consideration. The highest abortion rates are in CA, NY, NJ, DC, MA, RI, CT, MD, IL, WA, OR, etc. If abortion were back to being a state issue, the liberals could go happily on murdering themselves and throttling their future, while conservatives could forbid abortion in our part of the country. While I am morally opposed to abortion, even for liberals, I support liberal political and demographic suicide. Its fairly certain that even criminalizing abortion is not gonig to do anything to end it in those states listed above.
