More than three thousand individuals are behind the prison today without parole. Evade of parole is based on the crimes committed while they are juveniles. Seven states permit such type of law. The only country that applies life without parole before the age 18 is United States. Under Eighth Amendment, U.S Supreme Court decided to sentence individual to death for Roper v. Simmons in 2005. U.S Supreme Court decided to grasp the unconstitutional to sentence individual fewer than 18 for non-homicide cases. The above decision is made when Graham v. Florida apply with Roper v. Simmons reasoning to carry. Court sustains that obligatory sentence of life without parole for offense under 18 violates Eighth Amendment's prohibition. The actions of life sentence without parole haven’t convict non-homicidal offense. In 2010 U.S Supreme Court authorize the sentence that youth who haven’t commit murder to life without parole is not in accordance with a political constitution. Justice Anthony Kennedy originates the conclusion that the Eighth Amendment’s prohibitions against unusual and cruel punishment haven’t imposed parole possibility for juveniles under the age of 18th.
