The United States is one of the few countries that will sentence juvenile criminals to life sentences without parole. According to a new Supreme Court ruling, though, it's an unconstitutional practice, unless the crime was murder. Reuters reports that approximately 111 inmates are serving such sentences, mostly in Florida. The ruling was made on a 5-4 vote. Here's a copy of the court's decision.
There are about 2,000 offenders doing life-without-parole for murders committed when they were juveniles.
