NO, but it is certainly within the constitutions of some (most, all?) of the states.
No person shall be...... deprived of life, liberty, or property, without due process of law.
So you're telling me you think this DOESN'T COVER a child still in the womb? Even one in the late third trimester?More specifically, you're telling me that a woman can get a partial birth abortion 2 weeks before her delivery date, and the US COogress CANNOT pass a law against this (again, see amendment 5 above)?
Also, you still haven't reconciled the problem with your argument that YOU raised. One mailman (or other federal employee) kills another mailman (or other fed employee) inside a post office, or other area not governed by state law. Do you think it is unconstitutional for Congress to outlaw this murder?
