Ali al-Nimr was sentenced to beheading and crucifixion for participating in a protest at age 17. Raif Badawi was to receive a thousand lashes - a punishment sure to kill - for his blog posts. A Sri Lankan maid, whose name has not been released, was sentenced, on scant evidence, to death by stoning for adultery. These are just some of the people awaiting horrific punishment in Saudi Arabia for things most of the world would not consider serious crimes, or crimes at all. Saudi Arabia's justice system has gone into murderous overdrive. More than 150 people have been executed this year, the most since 1995. More than 50 people are reported to be scheduled for imminent execution on terrorist charges, though some are citizens whose only crime was protesting against the government. This wave of killing has prompted some to compare Saudi Arabia to the Islamic State: both follow Shariah law. Part of the problem is the lack of a penal code defining specific crimes and punishments, leaving judges complete discretion. That Saudi Arabia serves on the United Nations Human Rights Council makes this year's execution spree all the more egregious. It is shameful that the United States and other democracies that consider Saudi Arabia a valuable ally are so often silent in the face of such gruesome excesses.
