Given the decision mentioned in this link:
Kenyan court outlaws piracy trials
It would appear that there is currently no legal system in place that will (practically not theoretically) allow for Somali pirates captured on the high seas to be prosecuted....
Does that mean they simply have to be turned loose, after no doubt being told that they are "very naughty boys" (and girls, to stay PC), if they are actually caught in the first place?
