For those of you not familiar with the mother in question, there were actually 2 assailants at her house that night. She had a protective order against one of them. She was on the phone with 9-1-1, asking if it was ok for her to shoot them. The operator basically told her the he couldn't authorize her to use deadly force, but if they got in and she felt like she was in imminent danger (which she DEFINITELY was) then to do what she had to do. She shot the first guy through the door, and they both took off (IIRC).
Separately, a local military wife put up a post on FB yesterday. She was explaining how she was up with her 6 mo old daughter at about 4 am, playing and watching TV. Suddenly, it sounded like there was someone trying to get into her front door. Her husband is out for an FTX for 2 weeks, so she is by herself. It turned out to be the wind, but she said the moral of the story is: They need to buy a gun! Even she realized a knife is probably worthless against an intruder, especially if he has a gun or even just a knife. I wish more people thought like that!
ETA: I was off a bit on the details. He's a link to a story about it:
