Supreme Court Looking At Constitutionality Of Executing Young Killers

The Supreme Court is divided as it grapples with whether it's unconstitutionally cruel to execute 16 and 17 year old criminals.

The court has already barred execution of people under the age of 16, and during this morning's arguments, Justice Ruth Bader Ginsburg pointed out that American must be 18 to vote, sit on juries or to serve in the military.

Justice Anthony Kennedy said he's troubled by the cruelty of some murders committed by juveniles. Justice Kennedy said he doesn't want to get rid of a deterrent to such crimes, but noted the unrest of the world opposes executions of young killers.

Currently, there are 19 states that allow capital punishment for 16 and 17 year olds. Currently more than 70 juvenile murderers are on death row.
