It is to make sure the woman is fully aware of the consequences.
What a load of crap. This is coming from me, a person who was faced with the possibility of abortion three times. First time, I was pregnant with my twins when they found cancer...and it was too risky to proceed with the pregnancy as I needed to start treatment asap. I refused and kept my babies (one survived)...but I nearly died. Second, gang rape...they found 4 semen samples so there were at least four men but could have been more...I was left to die, which I almost did...and as a result, I was pregnant...I chose to keep the baby but I had every damn right to that abortion. And the third was recently...I just finished treatment with cancer (again) when I discovered I was pregnant - and the doctor urged me to abort because it would, not could but would, kill me...and the chances of the child surviving much longer was null...yet I refused. Sadly the baby's heartbeat stopped and they extracted the body.
So...yeah, there are special circumstances, and no one has a damn right to force me to look at a songram, law or not. This law is SICK.
