Jonathan, you just beat me to it. Justice Kennedy devotes an entire section of his opinion to examining how out of step U.S. death penalty practice is with the rest of the world. Thus, the “international” constitution once again rears its ugly head. It is no longer our right as Americans to define our own standards. Instead, we need to look to the U.N. Convention on the Rights of a Child to decide whether the State of Missouri can execute a seventeen-year old for the premeditated and cold hearted murder of random victim (who was tied, duct taped and thrown off a bridge, just for kicks). To be clear, this isn’t a question about the propriety of the death penalty. I’m perfectly happy to leave that to the individual states. It is a question of whether we should let 5 justices, who rely in part on international standards, to decide. Where’s Mark Levin when you need him?
