They went to the hospitals where the injured women were. They went to the morgue where the dead women had been brought. They went to the abortion mills where the injuries took place. They took the abortionists to court and eventually to jail. Now, when a woman is injured or killed in an abortion, nothing happens unless her family sues.
Nobody investigates and tries to put the butcher behind bars.
Thanks to Roe v. Wade, women are on their own. Roe didn't protect them, it simply guaranteed that seedy abortionists could kill them without any risk to themselves. This has never harmed innocent citizens. Most incest takes place in bedrooms. The police go into those bedrooms, collect evidence, and put the perpetrators in jail.
