Which leads, further, to one piece of radical common sense: since prison plays at best a small role in stopping even violent crime, very few people, rich or poor, should be in prison for a nonviolent crime. Neither the streets nor the society is made safer by having marijuana users or peddlers locked up, let alone with the horrific sentences now dispensed so easily. For that matter, no social good is served by having the embezzler or the Ponzi schemer locked in a cage for the rest of his life, rather than having him bankrupt and doing community service in the South Bronx for the next decade or two. Would we actually have more fraud and looting of shareholder value if the perpetrators knew that they would lose their bank accounts and their reputation, and have to do community service seven days a week for five years? It seems likely that anyone for whom those sanctions aren’t sufficient is someone for whom no sanctions are ever going to be sufficient. Zimring’s research shows clearly that, if crime drops on the street, criminals coming out of prison stop committing crimes. What matters is the incidence of crime in the world, and the continuity of a culture of crime, not some “lesson learned” in prison.
