Depends... What he was arrested for was blocking shark finning in protected guatemalan waters by trespassing costa rican fishers. He tries to stop whaling in the antarctic sea. They patrol and assist the navy in galapagos. They try to make sure no lives are threatened, instead they are the ones who get rammed by the japanese. They are trying to block the dolphin slaughter in Taiji.
Personally I support him. At least he has the guts to stand up for what's right.
