As I expected, Munk summarized the situation. What we want to see happen to the culprit(s) would end up diminishing us.
For the last ten years, or thereabouts, I've wondered if we could buy, say, Devils Island and ship all state and federal persons given the death penalty there. Punishment - to be burned at the stake on the end of their natural lives, and then buried in a nameless welded foot square box of one inch thick stainless steel to be dropped into the Mariannas Trench.
Difference in this Death Penalty law would be after a 3 month appeal period the judge would sign and file the death warrant. Prisoner John Doe would be called into court, read the death warrant, and the judge would revolk his birth certificate and cause all copies to be destroyed. Then sign and file the irrevocable death certificate, ending his "life". No appeals could be filed. His existence legally terminated.
The executee would then be taken to the place where he'd spend the rest of his breathing days though already legally dead. A place of no return, a place of no name, just another numbered shadow of the uninterred dead.
End of rant.
