**FILE**The execution chamber at Oregon State Penitentiary, shown here in Salem, Ore., April 25, 1997, has been used to put Charles Moore and Douglas Wright to death, both by lethal injection. Oregon state legislators have a tricky task ahead of them–how to implement the U.S. Supreme Court’s ruling last year that mentally retarded people can’t be executed. The court left it up to states to deal with the details – including how to define mental retardation, and whether a judge or a jury makes the determination that a criminal who could face the death penalty is mentally retarded. None of the 27 people now on death row have been found to be mentally retarded. Nor were the only two convicts to be executed since voters reinstated capital punishment in 1984.
