If you’re 17 years old and arrested for a crime, where you go depends mostly on what state you happen to live in. Although prosecutors and judges are usually able to pull teenagers out of the juvenile court system and charge them as adults if the crime is severe enough, nine states automatically classify 17-year-olds as adults. In North Carolina and New York, 16-year-olds always face adult courts.

But these states are the holdouts. In the last few years, Illinois, Massachusetts, New Hampshire, Mississippi, Rhode Island and Connecticut have raised the age of who is automatically considered an adult by the criminal justice system to 18. Plenty of policymakers still believe that certain individuals merit adult prison time no matter their age, but as a matter of blanket policy, lawmakers are increasingly setting the age of adult “criminal responsibility” at 18, citing the fact that adolescent brains are still developing at age 17 — and continue developing well into the 20s — and that these youths are particularly vulnerable to abuse in adult prisons.

Predictably, the justices were sharply divided about this important and new national restriction on capital punishment in America. Justice Anthony Kennedy, who wrote the majority opinion, cited the “susceptibility” of juveniles to “immature and irresponsible behavior.” Justice Antonin Scalia, in typically blunt tones, said in the leading dissent that the ruling made a “mockery” of the Court’s capital precedent.

Few people in U.S. know more about the Roper decision than Victor Streib, a professor of law at Ohio Northern University, who has devoted decades of his professional life to the study of capital punishment. Streib’s work was cited in Roper by Justice Kennedy, and over the past ten years, the academic has been no less diligent in watching the legacy of this important case develop, both at the Supreme Court and among lower federal and state courts.
