The German navy is expected to take part in direct action against pirates who seize vessels off the Somali coast on an almost daily basis. The seafaring bandits are getting ever more bold in their attempts to squeeze massive ransoms out of shipowners.

That's because some experts say that only the police can arrest pirates. But others are adamant that international maritime law does permit decisive action to bring the bandits to heel.
