Veritas, why is it that when a bear charges people in Anchorage folks like you always seem to consider it aggressive, but when people shoot a bear it's usually considered to be a defensive act? I'd say some (actually most) bear attacks are defensive and some (actually most, in my experience) human attacks are aggressive.  And there's a difference between hurting numerous people in one defensive attack vs. hurting numerous people in a series of defensive attacks.  Bear #2 would be much more problematic and should indeed be killed.
