Even if she was not the home owner wouldn't she have the same rights since she lives there. Just because they are not the owner doesnt mean they dont have a say in it. If someone is living at your house, wether it is a friend or relative you can't just say hey get out of my house and expect them to if they don't want to go. I had someone who was a guest at my house for a couple of days and one night they stepped over the line so I asked them to leave which they didn't so after calling the cops to remove them I was told since they had been there more than a day I would have to file an eviction notice because "they had a right to be there". Makes no sense to me at all. Then again this did happen in Commiefornia, maybe its different here.
I think if i was in Glock's shoes I would have done the same though.
