I don't believe minki whales are threatened now, at least any more than varieties of fish are. I'm just pointing to the outraged response to the killing of some whales compared to the "let them eat dogs, reindeer, anything they want - it's none of our business".
The problem with such whaling is that, while minkes aren't endangered today, the history of whaling demonstrates that prolonged hunting of whales means that they very possibly will be tomorrow.
The *only* reason minkes are hunted - they are one of the smallest of the balean whales - is that there simply aren't enough of the larger species left. They were hunted to the brink of extinction.
That said, there was some interesting research done a few years ago in Japan. A western researcher went there with a small, portable PCR set up and bought some commercially available whale meat.
He amplified DNA from the samples and sent it out of Japan to be sequenced.
Turned out the meat he had bought was from species (IIRC) such as right whales, fin whales and humpback whales - species that no one hunts (legally) and hasn't officially for something like 40 years.
Either the meat in question has been in the freezer for a bloody long time, or (far more likely) the embargoes on commercial whaling of endangered species are being ignored.
Oh, why PCR / synthesis of DNA? Well, if the researcher had sent whale meat out of Japan, he'd have breached CITES conventions.
By cloning the DNA, he was just sending manufactured products around - which is ok...
ETA: Oh btw - I didn't mean to imply he *only* bought whales that turned out to be endangered species. A lot of what he bought was minke and other species covered under the Japanese scientific whaling programme. But several samples were protected and very endangered species...
