“As far as selling them as chattel slaves, to whom could they be sold?”
I’d bet interested in buying one. Other are too, I’m sure.
“Once sold, they would no longer incarcerated and subject to the 13th. so no private or corporate entity could legally own them. Any such sale would be void ab initio .”
Incorrect. The 13th Amendment specifically permits convicted criminals to either be enslaved or committed to involuntary servitude. Constitutionally the law can be set that the punishment for a crime is enslavement. There’s no requirement under the 13th that the criminal be incarcerated while enslaved.
“Sometimes frum Jews are convicted of commiting a crimes, You know this would apply to them too”
Do you favor abolishing the death penalty, life imprisonment and other long term imprisonment? Those can r’l affect Yidden too.
