I dunno about this one. I'm not sure the authorities aren't right in this case.
If you do everything right - or even if you make a mistake and correct it - and then a bear gets you, the bigger risk is that the bear then decides humans are a prey item and seeks them out habitually because they are easy prey.... and people who do everything right habitually, start getting killed. Then you will see calls for reduction or elimination of bear populations - not great.
Maybe killing one Grizzly in these circumstances is the only realistic answer for the authorities: especially if they can do it quickly and ensure they get the right bear. Then everyone continues to enjoy that bit of wilderness - including all the other bears.
I'm not the biggest fan of humans in general and I think anyone walking to the North Pole shouldn't be armed, if a bear gets them tough cheese. But places people habitually go, and value partly because of the wildlife in them, require a balanced approach and I think this may be the best that can be done for both bears and people.
