My neighbor, in Baltimore city, had someone break down their door and enter into the house. When the unarmed homeowner told the individual to leave, the individual proceeded to attack my neighbor (older man) and aggressively beat them to the point of hospitalization. It went from nothing to life or death in an instant. When the cops showed up, they almost shot my neighbor (as he was delusional after the beating) but thankfully someone was outside and screamed that he lived there. They ultimately caught the guy hours later and because he was drunk/high, only misdemeanor chargers and was out by the next day.

If someone breaks into your house, they should be categorically viewed as an existential threat, especially given age, size, and strength disparity.

You have ZERO idea of someone's intention or capability when they break into your house, especially at night and especially if you are a woman.
