Sorry, I really thought I read in the Constitution something about life, I guess I was wrong. Oh, well.
The U.S. Constitution:
"We the People of the United States, in Order to...secure the Blessings of Liberty to...Posterity, do ordain and establish this Constitution for the United States of America." "No person shall be deprived of life without due process of law." "No State shall deprive any person of life without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution..."
