I didn't say that (black) bears can't kill a deer or moose, just that it probably happens WAY less than most people think. Why is it that bears love to hang out around dumps and other man mad garbage? Why is baiting one of the most successful methods of hunting them? Because they are opportunists that prefer to scavange than actually hunt. Sure they will kill something if the opportunity presents itself, but they typically kill WAY less than animals such as coyotes, wolves or mountain lions.
