But the court decision exempted full term babies from any limits of killing at the federal level?
Babies are in some special zone where their being killed by local government is completely outside of any federal consideration?
The rest it leaves to the states, or to the people.
Those who push federal power over the states try to show somewhere in the Constitution, where the Constitution grants the power to the Federal government.
Federal power has grown far beyond the constraints of the Constitution.
You could try argue abortion is murder, without due process under the 14th Amendment. You could argue most abortions are of "babies of color".
The problem is moral and cultural, not legal.
