Life does begin at conception. I don't need a legal manual to tell me that. That is when the unique DNA is formed. But anyways.
No, I don't think a miscarriage needs to be investigated if abortions were outlawed. The main reason is this: The point of outlawing abortion is to prevent idiots from using abortion as a form of birth control. There was a Seattle study done for women who aborted. The conclusion was this: Less than 10% of abortions that were performed were because of what I would consider legit reasons for abortion. 90% is because "I didn't have the money", "Baby daddy left me", "I didn't want the responsibility", "I was too young." Etc etc etc.
The reason people want to make abortion illegal is to force people to use their brains before they go and create a baby in which needs to be destroyed. How many parents would be in jail if they killed their child at 3 years old for the exact same reasons above? Why is it that it's still a fetus somehow makes it ok? Because it's just a fetus? It's just stupidity.
I know when I have a sex, the result can be a baby. If I'm not prepared for that, I either 1) don't have sex, 2) use birth control. Option 3) abort should not even be on the list of items. if choice #2 was used, and resulted in a baby. Well! I guess I rolled the dice and lost. But again, abortion should not be an option. Time to man up.
If you can just get rid of your child because your partner broke up with you or left you should not be a reason to eliminate your child. And if I remember right, that was over 50% in the survey results. If we were talking about a dog that was adopted, it even sounds ridiculous, and that is a pet. "I gave away my dog to the humane society because my bf broke up with me."
I don't think most people who want to outlaw abortion care much about the 10%, they care about the 90%...
