Reason has an essay up arguing that bad things may soon happen when ideologues seize on the science behind last-month's SCOTUS verdict, which ended the death penalty for people convicted as teens.

Already the immature teen brain argument has been used by legislators to impose various restrictions on teenage drivers, including limits on times they can drive, the number of passengers they can carry, and their use of mobile phones. That may appear reasonable; after all, teenagers do account disproportionately for traffic accidents.

Progressives who applauded the Supreme Court's decision with regard to imposing the death penalty might not be so happy when conservatives turn around and use that decision to justify imposing more parental consent laws on teenage women who are seeking an abortion. And will statutory rape lawsneed to be revised in light of the findings with regard to the immaturity of teenage brains? Furthermore, if teenagers aren't responsible for their actions with regard to violence, driving, or sex, how can they be expected to cast their ballots responsibly in elections? For that matter, how can teenagers responsibly sign up for military service? And surely the immaturity defense can be used by the tens of thousands of juveniles who are arrested each year for drug abuse offenses.

I think this is going to prove a real mess.
