Does the US Supreme Court still allows the execution of juvenile offenders who have committed very serious crimes?

Answer:
No. The US Supreme Court declared the execution of convicts who had committed a capital offense while still a juvenile is unconstitutional in Roper v. Simmons, (2005). The decision applied retroactively to juveniles and adults sentenced to death for crimes they committed while under 18 years of age. Those who had not yet been executed had their sentences commuted to life in prison.
