Good thing abortion isn't murder, and even if it were,
if according to the Supreme Court, police officers have no obligation to protect citizens, then the government has no business trying to protect a cluster of fetal cells in a woman's uterus.
Viability matters because you've picked date prior to viability to make it as hard as possible for a woman to get an abortion when even if she birthed the fetus 3 weeks later from your arbitrary date, it still wouldn't survive without major health issues.
You guys always rant and rave about getting the government out of your life except when it comes to forcing women to carry unwanted pregnancies to term, then all those "conservative" values go out the window.
