"Should Juvenile Criminals Be Sentenced Like Adults?"

The title of this post is the headline of this lengthy piece in The Daily Beast; it considers not just the hot constitutional topic of juve LWOP sentences, but the broader policy and practical issues involved in adult sentencing of juvenile offenders. The piece's subheading highlights the main case that is the focal point of the article: "Sean Shevlino was 16 when he robbed some local businesses. Sentenced as an adult, he’s serving 10 years. Is that better for anyone?".  Here are some excerpts fromt he piece:

Increasingly, social scientists, law-enforcement authorities, lawyers, and judges are questioning the wisdom of charging juveniles as adults. It is only in the last few years that the law has begun to recognize what science has long known: that adolescent brain development takes more time than previously thought.

"While some teenagers can be astonishingly mature and others inconceivably childish, middle adolescence—roughly, ages 14 to 18—might be the worst time in a person’s life for rational decision making, says Laurence Steinberg, an adolescent psychologist at Temple University. Research has repeatedly shown that during these years, pleasure centers are at full throttle, and foresight is lacking, particularly in young men.

“Among all American boys, about 75 percent violate the law at some point,” Steinberg says. “For some it might be as minor as possession of marijuana and for others it could be as serious as armed robbery, but in either case they’re breaking the law. The question we ask is why some stop and others don’t. Our sense is most stop because they just grow up.”

During pre- and early-adolescence, the brain becomes more efficient and logical, and dopamine activity increases. Things like sex, drugs, and adrenaline thrills feel really good, and when teens are in groups they are even more likely to go for the thrill. But as teens approach adulthood, the pathways between the brain’s CEO and the limbic system—the emotional center—increase substantially, allowing for greater impulse control. According to some studies, brain development is not complete until the mid-20s....

[S]ince 2005, several states have raised the adult criminal bar to age 18, either for some or all offenses. A state task force in North Carolina, one of two states where the age of criminal responsibility is 16, has recommended that for minor crimes, teens under 18 remain in the juvenile system.

The benefits of keeping juveniles out of the adult system are also financial. If the age were raised to 18 for misdemeanors and nonviolent felonies, North Carolina would net $52.3 million a year over the long run, according to an analysis by the Vera Institute of Justice.
