I understand the thought behind this but in practice it is a bad idea. You put the social worker in dangerous situation by putting them on the frontline before the situation can be assessed. The social worker feels unsafe and needs to rely in the armed police. This dependency creates a bond and they become part of the thin blueline family. In the end you are back in the same situation. The other thing to consider is a social worker is many parent's worst nightmare. If they find the smallest issue during a police call your kids could be taken away. Many people are afraid to call the police because they will call a social worker. I see this policy affecting single poor mothers in a much worse way compared to now. The other issue is a social worker isn't a hostage / crisis manager. They are trained to do very different things.
