These are all great points; I really like the idea of tying the hiring of new cops to increased ability for the city to investigate existing ones.

I think the housing crisis and the homelessness crisis— though it may sound outrageous, the cheapest way to end homelessness is to provide people with free housing— can be solved in part by developing more high-density housing in close-in residential neighborhoods. There's a ton of development going on in these areas already, but a lot of what I see there is single-family homes being torn down and replaced with larger single-family homes! Seems like a multiplex here and there would help a lot.
