If a woman in Mexico conceives a child and comes across into the United States and gives birth, that child is a U.S. citizen. So if you look at it the legal way, we have always treated birth as the determining moment. I think there are women who say, I want to decide as early as I can about getting an abortion, and I think they should. I think the only instance where abortion later in the pregnancy is reasonable is a situation like genetic defects, where you don't actually know until you get the testing done. So I think there are some instances where a woman cannot decide as early as she should, but early on it's easier, cheaper, better . . .
Statistics show that an early abortion is much safer than carrying a pregnancy to term.
But both, ultimately, are safe. Your decision shouldn't be made solely on medical consequences either way. But people who try to say abortion is unsafe, well, that's just not true. Justice Sandra Day O'Connor has commented that Roe is at war with itself. What I think she was really trying to say was that the legal doctrine was on a collision course with medical science.
