In Virginia, mandatory arrest for the primary aggressor in a domestic violence situation became law in 1997. There are 25 years of additional data that could provide valuable insight. The question is are domestic violence services effective, and if so, are the effectives ones available locally? So, do you research, and then take a look at Virginia services. Approach this from the perspective that someone you know and care about may need them, so you need some specificity in what the service is and how to contact them. Feel free to contact the service and do a phone interview with a representative.
