It appears British shipwrecks and actual ships lost in war - 'war graves' which are protected by national laws (in this case the UK, Malaysia & Indonesia), as well as the United Nations international law, are being looted, for metal that is uncontaminated and is highly valuable and policing it might be hard to do.
Tomb raiding, grave robbing and shipwreck salvaging, has been going on for millennia, making the this task even more difficult.
