I'm no expert but i'd imagine that IF these pirates are as clever as it's being made out they are, that much oil on a ship that big? First thing i'd do is booby trap the whole ship... Which i'd imagine would make a fukkin big mess of the indian ocean. Dont get me wrong i'm also pretty sure the SAS or US equivelent are already sat waiting to go, but if they can negotiate there way out of it, that probably the bast way too go.
