Which supreme court decision declared "life without parole" cruel and unusual punishment for juveniles?

Miller v. Alabama, 567 U.S. 460 (2012), was a United States Supreme Court case in which the Court held that mandatory sentences of life without the possibility of parole are unconstitutional for juvenile offenders.

i do believe   by (keeping an organized record of all sources he or she referenced)good luck.

explanation:

chavez's example shows that nonviolent protest can work well. it shows that one nonviolent man can stop a mob, which proves chavez's point and persuades people to protest nonviolently.
