Well, no s**t!! If a potential killer KNOWS they are going to get him, it will deter him. This "not a deterent" myth was made up by anti-death penalty jerks who simply asked a bunch of prisoners if the threat of the death penalty would have stopped them from committing the crime(s) for which they were imprisoned.
This is truly Clintonian!! If your kid is a murderer, shift the discussion to something else. It speaks volumes about the kid's guilt that the only thing they could find was the prosecuter's tie.

You beat me to it. That stuck out like a sore thumb.
