Actually I just read the article you posted in full MMM.

In it, it claims that

"Sea Shepherd Conservation Society acts in accordance with the U.N. World Charter for Nature. This charter provides for the enforcement of international conservation law by nation states, non-governmental organizations and individuals. Sea Shepherd Conservation Society is an anti-piracy organization and sinking pirate ships is sanctioned under international maritime law."

Those ships they sunk.. were apparently sanctioned by International Maritime law.

The Japanese ships of course are not pirates. But then again sea shepherd has not yet sunk any Japanese ships.
