"What does that prove?"

Fraid I've lost track of what "that" is, Raedwulf, and of who asked the question. But anyone who thinks CP helps save people from being murdered is not looking at the evidence.

Most developed countries don't resort to CP; no developed countries apart from (some of) the US executes people for crimes they carried out when aged 17 or less. Yet most (I would say all, but haven't time to check right now) developed countries also have lower murder rates than the US, lower levels of violent and gun-related crime and lower levels of crime by minors.

From this I rashly conclude that CP serves no deterrant purpose. OK, maybe it does give friends and relatives of the victims a short-lived, gratuitous buzz, but that's little to show for a punishment that kills the innocent and degrades us all.
