In summary, the book describes: how the concept of justice reinvestment developed and how its usage differs between countries; what a place-based approach means and why the Australian model is so unique in its approach; how measuring outcomes, as always, is fraught with complexities, but how the approach used is also such an important determinant of understanding what does and doesn’t work; and how marginalised and socially disadvantaged groups — those usually affected by policies that lead to mass incarceration — may or may not benefit from a place-based approach to justice reinvestment.
