The 13th (XIII) Amendment (1865) reads as follows:
Section 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.
Section 2. Congress shall have power to enforce this article by appropriate legislation.
This is in direct violation of Amendment VIII (1791) which states : Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.
In the land of the free there should be no exceptions made for slavery.
