The IWC expressly allowed the Japanese to conduct their research, and they have never violated any law, except for whaling in a fake sanctuary.
In tonights show, yes, in the Faroes, between ireland and Greenland, they make it clear the hunt is legal, and noot for an endangered species.
But seeing it's Sea Shepherd I'm hoping for self prop-fouling, idiots in those stupid rubber boats get lost, someone started a drinking game. My old PC crashed and I lost the rules.
But if you follow the Whale Wars drinking game you'll be smashed about five minutes into the show.
The whales being hunted are not endangered.
