Omestic Violence and Criminal Justice System

The title of the essay is optional. I would like the essay to be about Domestic Violence specifically the criminal justice response to domestic violence. for example how has the criminal justice system impoved in relation to domestic violence victims in the recent years? or to what extent did the Domestic Violence, Crime and Victims Act 2004 improve the protection of victims involved in domestic violence, or could there be alternatives to the 2004 Act or even an analysis of the advantages of domestic violence becoming a new and seperate criminal offence in order to provide greater protection to victims suffering from domestic violence
