IMO wrong. Domestic abuse will continue as long as women are willing to live with bad men. Men don't generally change, and the signs will be there at the beginning.
Some women, IMO, are so desperate to get married that they will marry anyone that asks no matter how bad he is, then they complain when he behaves in the way he always did.
My ex married a bad man that she knew was bad. When I asked her why she married him if she knew he was a violent drunkard, she replied that "she thought she could change him"! She didn't leave him till after he traumatised the two children that they had together.
BTW, cops are not social workers.
