I certainly don't have the right to kill someone inside that land who's there through no fault of her own, and if I do, it's not outside the government's jurisdiction because it happened inside what I own. It happened to someone I don't own, and that's the key issue. (Or, rather, I did it to someone I don't own, and would therefore deserve punishment.)
Do you or do you not have the right to expel the tresspasser (and to use lethal force if the intruder refuses to comply)? What is different when someone is tresspassing on your body?
And you still refuse to answer the question, Aaron. What is the penalty do you propose for this act of pre-mediated murder? Death? Be very careful with your answer, because, throughout history, juries have refused to convict women for infanticide. Never mind abortion.
