Do you agree with the court that executing minors who commit capital crimes offends the “evolving standards of decency that mark a civilized society” and is thus cruel and unusual punishment?

Do you agree with the court that executing minors who commit capital crimes offends the “evolving standards of decency that mark a civilized society” and is thus cruel and unusual punishment?
