Agreed. The other useful proposition I've heard is to make an inventory of all the things we use the police for that really aren't supposed to be a part of their jobs (such as mental health crisis response where there isn't a danger of harm to others), and create separate departments to deal with those. Then you can slowly transition to a point where the police are just doing police things, instead of being the catch-all for all the stuff nobody else wants.

Eugene, Oregon has been running a program called CAHOOTS for several years now, and Portland is starting to mimic it. It's basically a team of mental health professionals who roam the city responding to mental health issues that don't require an armed response. It seems to be working pretty well for them, and I think the model could be expanded.
