A fairly large statistical portion of domestic violence is female to male, and the stereotype of the wife-beater has certainly led to a lot of false prosecutions against men (falsely accused of being the aggressor) and situations that police ignored until a female assailant escalated to deadly force.

I used it because it's the standard placeholder of an unwitnessed violent crime in law enforcement discussions.

Perpetuating harmful stereotypes is not cool in any case. Sincere apologies. I lieu of editing, since the time's elapsed, have some karma :)
