Dang. That wouldn't be a fun way to go at all. Bears are scary, scary animals if one ever got mad--in terms of strength and killing ability a bear is actually much more dangerous than any of the predatory wild cats out there. Reading the link Spf provided, it looks like they were watching this bear not knowing that it's cub was around, bear felt threatened and attacked based on its instincts.
