Flutterby™! : Prison makes society less safe

Or, at least, prison doesn't make society any safer, and probably makes it less safe: Crime and Justice: a review of research — Custodial Sanctions and Reoffending: A Meta-Analytic Review https://doi.org/10.1086/715100

Every review has reached nearly the same conclusion: compared with noncustodial sanctions, custodial sanctions, including imprisonment, have no appreciable effect on reducing reoffending. The studies tend to show that placing offenders in custody has a slight criminogenic effect, although this association is not sufficiently robust to argue for its certainty.
