These stories are always out there. I dated a girl who was 5'10 and I'm 5'11, during our breakup it got sideways one night. Started out with just arguing, then she began to get physical, punch after punch. I finally made it outside, a buddy of mine was meeting me at her house and showed up she swung on him hitting him in the mouth. I turned around picked her up and put her on the ground. Welp next thing you know her Mom has called the cops, two cars showed up and I was about 5 minutes from a trip to jail. Thank goodness my friend was there and the girl said it is not his fault or guess what I'm guilty of potential DV.
I don't judge CB because it was one time, my occurrence was one time. To label someone for one offense which didn't lead to an arrest is foolish IMO.
