Why Don't We Hang Pirates Anymore?

Great question:

In March 2006, the U.S. Navy took 11 pirates prisoner, six of whom were injured. Not wanting to set a precedent for trying pirates in U.S. courts, the State Department turned to Kenya to do the job. The injured spent weeks aboard the USS Nassau, enjoying First World medical care.

All this legal exquisiteness stands in contrast to what was once a more robust attitude. Pirates, said Cicero, were hostis humani generis -- enemies of the human race -- to be dealt with accordingly by their captors. Tellingly, Cicero's notion of piracy vanished in the Middle Ages; its recovery traces the recovery of the West itself.

By the 18th century, pirates knew exactly where they stood in relation to the law. A legal dictionary of the day spelled it out: "A piracy attempted on the Ocean, if the Pirates are overcome, the Takers may immediately inflict a Punishment by hanging them up at the Main-yard End; though this is understood where no legal judgment may be obtained."

Severe as the penalty may now seem (albeit necessary, since captured pirates were too dangerous to keep aboard on lengthy sea voyages), it succeeded in mostly eliminating piracy by the late 19th century -- a civilizational achievement no less great than the elimination of smallpox a century later.

Today, by contrast, a Navy captain who takes captured pirates aboard his state-of-the-art warship will have a brig in which to keep them securely detained, and instantaneous communications through which he can obtain higher guidance and observe the rule of law.

Stephens' has a great close:

Piracy, of course, is hardly the only form of barbarism at work today: There are the suicide bombers on Israeli buses, the stonings of Iranian women, and so on. But piracy is certainly the most primordial of them, and our collective inability to deal with it says much about how far we've regressed in the pursuit of what is mistakenly thought of as a more humane policy. A society that erases the memory of how it overcame barbarism in the past inevitably loses sight of the meaning of civilization, and the means of sustaining it.
