[10.31.11] Roe v. Wade

Facts/details
1) Some say that anti-abortion laws were previously established to "discourage illicit sexual conduct."
2) One of the reasons why abortion is limited to only the first trimester is because the mortality rates are lower or just as low as childbirth. (So the states consider women's health, too.)
3) The right of privacy, although not explicitly noted in the Constitution, covers a woman's personal choice whether she wants to get an abortion or not.
4) However, the right of privacy is not absolute. An example of this would be getting vaccines.
5) The state also considers a woman's mental health when an abortion is concerned.
6) One has to consider people might believe "life" begins at different time (eg birth or conception).
7) Some consider conception to be at the point where "the fetus becomes 'viable,' that is, potentially able to live outside the mother's womb, albeit with artificial aid."
8) A state (or the government?) is required to preserve and protect the health of a pregnant woman, "whether she be a resident of the State or a nonresident." (Relations between states)
9) A state will also consider a fetus' life after viability when setting when an abortion is allowed.
10) The Texas Penal Code said that abortions were only allowed when the mother's life is in danger, but it isn't legit. One of the reasons is because abortion during the first trimester may be less dangerous than normal childbirth.

Questions
1) How would one distinguish from a private choice and one that is not?
2) This is a biased question - but how would a zygote not have life?
3) How will "point of conception" be established?
4) Will there possibly be a reversal of Roe v. Wade in the future?
5) Will abortion be a point that companies and others consider when hiring? (Eg the West Wing episode) Would this be legal?
