““Once the criminal has served his time, he returns to his old neighborhood. There’s a good chance he’s been psychologically damaged by his time behind bars. His employment prospects have plummeted. While in prison, he’s lost many of his noncriminal friends and replaced them with fellow-criminal friends. And now he’s back, placing even more strain emotionally and financially on the home that he shattered by leaving in the first place. Incarceration creates collateral damage. In most cases, the harm done by imprisonment is smaller than the benefits; we’re still better off for putting people behind bars. But Clear’s point is that if you lock up too many people for too long, the collateral damage starts to outweigh the benefit.””
