She was 28 weeks (6.5 months) pregnant. The survival rate for babies born at at 28 weeks is 80%. ( source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1117667/ ). This wasn't a fetus, this was a fully formed baby.
I fully support right to choose, but this wasn't abortion...it was murder followed by coverup. Everyone getting riled up over the social justice of this has plenty of things to be riled up over these days, but this isn't one of those things.
At what point do you think it's unethical? Or do you have no line that can't be crossed. At 28 weeks, it's a fully formed baby that can survive outside the womb with an 80% survival rate....that's way past any reasonable and ethical line.
