"Maybe the neighbours were sick of hearing the same shit every night, finally reported it, finally took all details and finally went to the media."
What is the point of conjecturing about it?Maybe the plates were thrown by her? The point is no-one knows what happened except the 2 people involved.
I'm sorry that you experienced an abusive relationship but, just because you did, doesn't mean this is DV.
I remember as a child my mum breaking every piece of crockery in the kitchen against the door. My dad didn't do anything to warrant it. My mum was just frustrated and lacks the ability to communicate effectively due to her childhood life. If that had been recorded I dread to think what the police would have thought about it.
