idk that the chief is the problem. It's the union. The chief is relatively new (2017).
He's the first black police chief in Minneapolis.
I really don't know what tools are at anyone's disposal, but the MPD has long legacy and people are sick of it.
I'm sure not everyone agrees, but this is the sentiment in possibly the poshest part of what you might consider downtown, aka my neighborhood (Mill District is up there too): https://twitter.com/ModistBrewing/status/1266219334352994304
