According to this article David Cameron is considering creating a specific offence of domestic violence ( as opposed to common assault, abh, gbh etc) which takes into account the controlling and abusive pattern of dv.
I think it is potentially a good idea as Dv is not just violence but the violence is the main thing that is prosecuted. However it would have to involve the police and other criminal justice agencies being properly trained in how to recognise and deal with Dv cases and all the complexities involved. What do people think, is it a good idea?
