It would probably need support from police/ex-police to be truly effective. One of my in-laws was with the highway patrol for over a decade and it's interesting how it changes someone when they're around crime all the time. It does something to the human psyche to be around violent or dishonest people all the time so it might be very difficult to find cops/excops to help reforms because most have probably had their outlook of people/society permanently changed, often for the worse.
