I'm not quite sure if this will even show up, being a new member, but anyways, I thought I'd make a less hostile reply, as you've asked a question.

The Duluth model has shaped public policy and lawmaking for a few decades now, painting the picture of domestic violence where men are the aggressors, and women the victims. Campaigns against domestic violence almost always portray a battered woman, and some shelters or support structures for victims outright refuse to help men, or redirect them to batterer's resources.

Does it not seem credible that this pervasive social policy would influence the behaviour ans reactions of individual police officers, even when they aren't obligated by policy to arrest the male?
