Do these people not own guns?
I'm fairly sure that if I saw, with both of my own two eyes, a bear inside my house, the first thing I would be doing) unless the bear was actively charging at me at that very momment) would be trying to put my hands on a gun - and preferably the biggest one I owned.
I do not think I would head downstairs after it bearhanded (no pun intended but it sure is a good one) and then pick up a baseball bat and start waling away at it.
But then I've never experienced anything like that. Maybe seeing a bear inside your house causes your brain, as well as other stuff, to run down your leg.
