“Only three countries - Iran, Saudi Arabia, and Sudan - are known to have executed an individual since the beginning of 2009 for a crime committed before age 18, Human Rights Watch said today. In advance of the World Day Against the Death Penalty, October 10, Human Rights Watch called on the three countries to immediately end the practice.”

By outlawing the juvenile death penalty in the United States, Roper v. Simmons established a legal consensus and reflected an evolving standard of decency nationwide. Following the decision to affirm the juvenile death penalty in Stanford v. Kentucky, individual states began outlawing the practice one by one and rendering it obsolete. Readressing capital punishment and reaching a changed outcome demonstrated the overcoming of the barrier between states and the federal government. While capital punishment for minors remains a controversial subject nationwide, Roper v. Simmons ultimately had major effects globally and domestically.
