Here's a good you for you. The link is to an article about a bear bagged by a hunter in Canada's Northwest Territory that is half grizzly and half polar bear, a mix that some experts had never expected to find in the wild.
They say without the DNA results the hunter was facing the possibility of a $1,000 fine and up to a year in jail for shooting a bear for which he had no permit. The hunter had paid $50,000 for guides and a permit to hunt polar bear. Without the DNA, he was going to be out a lot of money as well as well as loosing the trophy.
