Virginia's 2012 HB 1 sought to define personhood as beginning at conception:
§ 1. The life of each human being begins at conception.
§ 2. Unborn children have protectable interests in life, health, and well-being.
§ 3. The natural parents of unborn children have protectable interests in the life, health, and well-being of their unborn child.
§ 4. The laws of this Commonwealth shall be interpreted and construed to acknowledge on behalf of the unborn child at every stage of development all the rights, privileges, and immunities available to other persons, citizens, and residents of this Commonwealth, subject only to the Constitution of the United States and decisional interpretations thereof by the United States Supreme Court and specific provisions to the contrary in the statutes and constitution of this Commonwealth.
§ 5. As used in this section, the term "unborn children" or "unborn child" shall include any unborn child or children or the offspring of human beings from the moment of conception until birth at every stage of biological development

If this bill had become law, what would some of its effects have been? Would it have made a woman who got an abortion not specifically protected under Roe v. Wade criminally liable for murder? What other interesting consequences might it have had?
