RCMP not withstanding, the police are managed by the communities, if you consider a city council to be / represent the community. I know that here in Halifax, there was a Defund The Police™ study with a bunch of community input from the usual intersectional types. I took a read. It had a few good suggestions, but also some talk of seriously reducing the force size altogether. The problem that was not addressed is that last year we had a tit-for-tat killing spree between a couple of gangs in a predominantly black community that seriously spiked our murder rate. I don't know how defunding the cops would have helped that particular situation.
