So... Are you saying "Shoot all the journos"? Because I'm with you if you are... A bit of the old "What the eye don't see... etc"... would work just fine in that part of the world...
Or we could trade them for the hostages. The rich media tycoons can afford the ransoms and journo gets his story on release. The only proviso would be that the pirates have to keep them for 10 years first.....
