Perhaps I am being the Fun Detector here - but are we sugesting extra-judicial killing of pirates? This country, and indeed most in the Western World work on the proncipal of rule of law and independence of the judiciary. Let's not confuse a lack of action (cf UNCLOS III, 1982) with the need for a violent resolution.
These pirates are causing a considerable nuisance, I agree. However barbaric acts of violence - as hinted in the Russian recording - kis not, repeat, not the solution.
