Counsel Them Early
More people will report men who show early signs of being abusive towards women if all that the reported man was required to do was to attend a counselling session discreetly. In the session there could be men and women who are not reported but are volunteering to make the community safer. Women learning self defense and also why reporting early can help.
I think interventions like counselling have cut down on drunk driving and so on but why this idea is different is tht it combines potential abusers with volunteers and potential victims. Not sure if this approach will work or whether it has been tried before. Just because something has not been tried before does not mean it should not be tried.
