Yes, that could be one possibility. That said, we have to consider another factor. You may find it strange for me to mention this, since our mission is to work with victims of violence, not the perpetrators.
When the police intervene, it tends to be unsettling for perpetrators of violence. This is no ordinary day for them. It is a good time to direct them to resources that can help. It's very important to do that, because it is impossible to put all perpetrators of violence in jail. It's not going to happen, unfortunately, because there are too many of them. In addition, the criteria for keeping a person in detention are not always met.
The police need to use the intervention to refer perpetrators of violence to help services. It has to be done quickly, and they should be subject to rigorous follow-up.
