I don’t answer the door at 2:30am. Heck, I’m not likely to answer after :009m on autumnal or winter nights. Simple too dark outside to see who it is and no, I don’t want to turn on the light and let them know there is someone home.
Someone knocking and yelling to call the police? Yes, I’ll call the police and then wait & watch. Still not opening the door though, no matter how much knocking is going on.
2:30am is also just post bar scene closing time.
I think there is information missing from this story. Most folks I know would not even open the door, so what really happened?
White neighborhood. Black “female yout” at the door at 02:00 hours. Could be “friends” hiding out of sight. Reasonable to assume.
