Of America's 50 states, 28 (more than half) prohibit executing those who were younger than 18 at the time of their arrest (1).
In Atkins v. Virginia, the Court also said there was an international consensus against executing the retarded since most nations refuse to do it. As Stevens put is, "Within the world community, the imposition of the death penalty for crimes committed by mentally retarded offenders is overwhelmingly disapproved."
Is the same true of executing juveniles? Absolutely. The world has more than 190 nations. Since 1979, only five of those nations have executed juveniles: Rwanda, Pakistan, Barbados, Bangladesh, and the U.S.A. (2).
Pakistan recently agreed to stop (3). They are stepping forward in human rights and fairness for children and teenagers, while the U.S. Supreme Court keeps America's legs shackled.
Yet another reason given for not executing the retarded: while the death penalty is often accepted and supported as a deterrent to crime, it cannot deter those who lack the mental capacity to understand the risk they run by breaking the law.
Shouldn't the government use this same reasoning for youth? Think of all the times we've heard a law-maker defend some new age-restriction by telling us, "Kids all think they're invulnerable. Kids think bad things can only happen to other people." If this is true, no penalty can deter youth from breaking the law since youth will assume they're invulnerable to capture and punishment. Therefore, executing youth is pointless; and to kill someone pointlessly is cruel. If, on the other hand, it is not true that youth "all think they're invulnerable," then politicians should admit it is a lie and should stop using this lie to justify everything from age-restrictions on driving to age-restrictions on tobacco.
The Supreme Court further declared we must stop executing the retarded because "their impairments can jeopardize the reliability and fairness of capital proceedings against mentally retarded defendants." In other words, the retarded have a hard time defending themselves and getting a fair trial. What about youth? Can teenagers get a fair trial? Juveniles are not even allowed a jury of their peers. And given America's current political climate of hostility against youth, it's hard for old jurors to judge young defendants fairly *.
Despite all these parallels, the Supreme Court banned executing the retarded by a 6-3 vote; but the same Court refused to even hear arguments against executing youth. To their credit, Justices Stevens, Breyer, Ginsburg, and Souter voted to hear the case. But they were outnumbered by the rest. The remaining five included O'Connor and Kennedy, who had voted to protect the retarded from execution, but who now voted to turn a deaf ear to the pleas of the young.
