On the point of the Court's Roper decision: I watched one television commentary on the case in which the host had one person defending the opinion on the ground that people should not be subjected to capital punishment for crimes they commit when they are younger than eighteen, and the other person attacked the opinion on the ground that a jury should be able to decide that a person, despite the fact he was under eighteen, given the crime, given the person involved, should be subjected to capital punishment. And it struck me how irrelevant it was, how much the point had been missed. The question wasn't whether the call was right or wrong. The important question was who [i. e., the Courts or Congress] should make the call.
