Moreover, we have very little evidence that longer sentences themselves do much to deter serious crimes. Monthly readers may be familiar with the late, great Mark Kleiman’s work in this area, summarized in his classic work, When Brute Force Fails: How to Have Less Crime and Less Punishment.

Keller recounts conversations with many people incarcerated during the early 1990s. These men and women committed murder or other serious crimes. They’re also not the same people they were 30 years ago.
