For those of you who don't know the Sea Shepherd Conservation Society is an environmental activist group dedicated to the protection of sea life. They're most famous for their multiple campaigns against Japanese semi-legal whaling operations, and the television show about said campaigns. They're known to use active, radical and semi-illegal tactics in their anti-whaling operations including throwing butyric acid grenades on to whalers' decks, water cannons, poisoning the corpses of harpooned whales, ramming, and even placing limpet mines onto whaling vessels. Plenty of people praise them for their activist measures, and plenty of people call them "eco-terrorists" and pirates. Simple enough what do you think? Are they in the right or the wrong? Should either or both sides be arrested? And who was responsible for sinking the Ady Gil?
I personally think that in this case two wrongs make a right, when someone commits a crime and gets away with it people need to take the law into their own hands. I also consider the Shonan Maru's captain at fault for the sinking of the Ady Gil as the Sea Shepherd boat was idling when it was rammed.
