I do wonder how that is going to work in practice though. Who are people going to call when they get robbed, or when their child gets raped? Ghostbusters?
I already mentioned it, but there are other places that did this exact thing, with good results. So it's not something people have to go in blind. Just go ask the council in Camden, New Jersey how they did it.
https://www.citylab.com/equity/2018/01/what-happened-to-crime-in-camden/549542/The trick with Camden is that you scrap the department completely, then you create a new structure and put your selected people in charge. Remember the guy who knelt on Mr Floyd's neck was the
training officer for two of the other officers on that day. So you
have get rid of the old department and make your own new department, and you strictly control the training processes as well as implement a strict disciplinary process. The rots already set in, but if you make your own new organization then you can better control how that operates.
Then you drum deescalation into the new officers during mandatory training, as well as making them sign off that they clearly understand what they're supposed to do if another officer, any other officer, doesn't follow the protocols. The important thing here is that you put your own command and training structure in place, guys who have been hired on the express understanding of what outcomes are required. If you leave the existing command structure in there and try and reform it, what they'll do is sabotage everything with a wink and a nod that you're just supposed to ignore the deescalation training, because the pencil-pushers don't know how it is "on the streets" and that the department will cover for you no matter how you fuck up, then they put a neck-stomper in charge of training to show the rookies how things are meant to work.
