NC for anonymity reasons. I'm not from the UK so not sure how this sort of thing would be handled here.
I was recently walking past a local park and saw something of a domestic scene. A man had parked near the entrance to the park and was standing with his door open. I heard him yell and shout angrily but could't make out what he was saying. As I walked closer I realised there was a woman with two children there. He yelled again "You knew how I was going to react. Now put my children in the car." She stood there silently and with a blank face, holding the children. The children (maybe 9 and 12 years?) also stood by her silently, no tears or yelling or trying to run to either parent. It seemed to me this was not the first time this had happened. (I have personal experience of domestic abuse and this was far too familiar to me, unfortunately).
The woman and children stood silently on the kerb, it seemed waiting for the man to give up and go away, and he got back in the car and closed the door. I continued walking and thought about asking if they needed help but didn't. I walked to a nearby corner to make sure she seemed safe. He yelled more and the woman and children got into the car. (From appearances she and yelling man were the parents). He drove away somewhat aggressively.
I didn't ring the police because i didn't want to put the woman/children in any danger. I also didn't ask if she and the chidren needed help, for the same reasons. I also noticed the man was not white and she was (I am also not white) and i do think twice about calling policed on non-white people. But the safety of the woman and children would be paramount I think but I was worried about making things worse for her, mostly.
But his voice has been haunting me and I worry for her and the children's safety. What would you do in this situation? Ring the police or non emergency police? Is there someone else to call? I did note the car registration plate number. Thank you.
