....The rush to try more and more children as adults began in the 1980s when the country was gripped by hysteria about an adolescent crime wave that never materialized. Joe Sullivan, the petitioner in Sullivan v. Florida, was sentenced to life without parole in 1989 — when he was just 13 — after a questionable sexual battery conviction. His two older accomplices testified against the younger, mentally impaired boy. They received short sentences, one of them as a juvenile.

The case of Terrance Graham has similar contours. A learning disabled child — born to crack-addicted parents — Mr. Graham was on probation in connection with a burglary committed when he was 16 when he participated in a home invasion. He, too, had older accomplices. He was never convicted of the actual crime but was given life without parole for violating the conditions of his probation.

These were two very troubled children in need of adult supervision and perhaps even time behind bars. But it is insupportable to conclude, as the courts did, that children who committed crimes when they were so young were beyond rehabilitation. The laws under which they were convicted violate current human rights standards and the Constitution.
