5. Humberto Leal Garcia

SOURCE

Garcia was a Mexican national who entered the U.S. and raped and killed a minor girl in 1994. When he was arrested, his lawyers claim that police never told Garcia that he could have contacted the Mexican consulate, since he was a citizen of Mexico. Police said that Garcia never told them he was from Mexico. Though the Supreme Court found that Garcia’s rights had been violated based on international law, the court had no jurisdiction or power to compel a state to abide by international law, and as a result Garcia was put to death via lethal injection in 2011.
