With regard to the Chris / Rhianna story, those of us who have worked in the field of domestic violence intervention (which I did for almost eight years) see it as a fairly textbook example of a domestic violence episode: assault, report and medical intervention, review of case by prosecutors and possible charges, and later reconciliation between the abuser and the victim. And dropping restraining orders filed by the victim. And asking prosecutors or the court to drop a no contact order issued from a pending criminal case. This is far more common than a victim separating from her abuser and staying separated, especially victims in Rhianna's age group.
I think this is an important story to keep playing for awhile, because it at least sparks dialogs within families and within social groups as well as in the media at large. I did find it gratifying that (I think) MSNBC posted an online story stating, importantly, that strangulation ("choking") within the context of a domestic-violence event is a very good indicator of future homicidal violence. Strangulation has come under increasing scrutiny in the field of domestic violence intervention, and many states have now made it a felony to strangle an intimate partner regardless of the level of injury sustained.
Regarding "helping" intimate-partner beaters clean up their act . . . meh. The domestic abuser is of a very distinct personality type, and that personality type feels he is doing nothing wrong. Very gifted at presenting a meek, calm face to the world (as well as to the victim in the early stages of the relationship), the mask can come off in a second when the abuser is in the mood to control by whatever means necessary and whatever the abuser is in the mood for. And I have yet to see a successful treatment program for that.
