Calling the police is should only be viewed as a nuclear option. Once you do, you surrender control of the situation, and the relationship will never be the same. I have never seen it work out positive for teens or parents. So, if the situation is desperate enough to nuke the family, then it might be the police need to be called, but you cannot expect the teenager, or whoever the family member is that calls, to be understanding or even forgive.
That is a good question, one with multiple answers. It may also well be that the police are the greater danger in these situations. Likewise, we have social workers and mental health professionals dealing with people all the time without police being by their side. Doubling the people who respond doubles the taxes that pay for them, so there’s that.
Yes, it would require funds, like defunding that part of police work to pay for social workers to answer these types of calls, as part of their case loads. For now, answering all crisis calls makes no sense, but I could see a transition possible to where they answer those crises involving someone in the case load. I know that takes money as case loads would have to be less to allow for this sort of response.
Or, there could be a response specialist on call for a region, to answer those under their case management.
