Justice Kennedy does it again. The uber-legislator rules for the liberals on the Court that the death penalty is unconstitutitional for murderers who happen to be under 18, with this reasoning: “When a juvenile offender commits a heinous crime, the state can exact forfeiture of some of the most basic liberties, but the state cannot extinguish his life and his potential to attain a mature understanding of his own humanity.” “A mature understanding of his own humanity?” Someone want to explain that one to me? For those of you who follow these things, perhaps it just means “the right to . . . .define one’s place in the universe.” Oh, I give up.
