The book stipulates that providing free housing would reduce crime committed by people who are unhoused. It also advocates for free health care for people and social workers for people who suffer from mental illness. Some will refuse treatment, as we already know. But not all. The book does not say that crime will end. It does make ten (I think) excellent points as a chapter each about failures of policing to address social problems. And it has damning statistics to back up the claims.

It's ridiculous that the richest nation in human history refuses to spend money on people in need other than for the purposes of enforcement. Doing so is counterproductive and wastes more money than just helping people. That's my take.
