In the UK, every year, over 100 women and 30 men are murdered due to domestic abuse and the average is 35 assaults before the police are called. (Some people never call the police).
And what about all those neighbours who pretend to be deaf or turn a blind eye to someone's suffering?
My stepcousin was killed by her partner in Australia. She had four young children and the youngest has no memories of her mum thanks to that pathetic excuse for a human being. (I'll never, ever, forget that phone call from my aunty).
