Until someone can show me where murder is incorporated in the list of things the founders tasked the fed. gov with taking care of you lose!
Either the plain words of the Constitution have meaning or they don't.
The protection of those accused of crimes, even capital crimes, are laid out. If we would not propose to deprive even a heinous criminal of their life without first finding them guilty of that crime, with the protections of the accused inherent in the Rights set forth in the Bill of Rights, what evidence is put forth that a child, within its mother's womb, as yet incapable of any crime, should be subject to Capital Punishment. Ironically, many of those who call for the summary judgement of death upon these innocents, would quail at the thought of executing even the most vicious duly convicted murderer.
Fifth Amendment:
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.
Don't know where a baby falls in that, but it sure seems to me the Founders and other folks of that age held life dear.
Of the unalienable Rights we are endowed with by our Creator, Life was mentioned first, followed by Liberty and the Pursuit of Happiness. That order indicates a primacy of that Right to Life, above all others, first and foremost, and without which all others are moot.
In the absence of evidence proving beyond a reasonable doubt that a developing baby had committed some crime worthy of their execution, I can see no Constitutional protection for the practice of aborting the developing child at any stage of development, and decidedly none for the execution of a baby which had been born, be that done by commission or omission (of care).
