What do we do with pirates?

Somali pirates have killed four Americans and our armed forces have captured about 15 of them alive. Now what?

This isn't a difficult case. It's obvious piracy. It's obvious murder. And there are fifteen people who are complicit. Who did what doesn't much matter.

What we should do with them now is a problem. What we will do is doubtless bring them back to this country, give them respectable trials, and lock them up for decades at public expense.

This is not the way piracy has traditionally been dealt with on the high seas, and the 15 pirates should accidentally fall overboard. It would send a healthy message to their comrades in Somalia.
