I would hazard the guess; given the rampant corruption within all Institutions of the Philippines, that this incident has less to do with maintaining territorial integrity and far more to good old fashioned extortion. - Meaning that Freelancing Coastguards extort "fines" from Fishing Boats and turn nasty when refused. Its not he first time that I have heard the Philippines Coast Guard and Piracy mentioned in an unflattering way, in the same sentence. Its not the first time that a Taiwanese Fisherman has died in a hail of automatic fire from them either. Will China exploit this incident in pursuit of its claims? You betcha!
