we had several of those before we moved. I bought a scanner so we could listen and see just how close they were. One day an unmarked car pulled up to the house across the street so i got the scanner and heard a code 51 (IIRC) as backup came. I looked up <my city> police codes and found that a code 51 was stabbing. Later the police escorted the lady living there and her kids to pack what they could in a trash bag and leave and she had a big bandage on her neck. We got to talk to her, took her kids in our house so she could go pack her stuff and found out that her baby daddy had found them and stabbed her so she had to move to a new place.
