What Works in Sentencing? Evidence from the United States Cassia Spohn School of Criminology and Criminal Justice Arizona State University
Two Questions • Have the dramatic increases in the number of persons imprisoned in the U.S. led to a reduction in crime? • Have the sentencing reforms (e.g., mandatory minimum sentences and sentencing guidelines) implemented over the past several decades produced the predicted instrumental effects?
What Caused the Imprisonment Boom? • Increase in crime • Problem: both violent and property crime rates declined as imprisonment rate increased • Increase in likelihood of imprisonment given arrest* • Increase in length of time served*
Did Changes in Sentencing Policy and Practice Reduce Crime? • Targeting dangerous, high-rate offenders can reduce crime through incapacitation • But, increasing the severity of sentences has had little, if any, deterrent effect on crime
The Deterrent Effect of Mandatory Minimum Sentences • Evidence suggests that they have little (if any) effect on crime • Evidence also suggests that • MMs are frequently circumvented or manipulated by prosecutors, judges, juries • Factors that predict use of MMs are not racially neutral • Practitioners often believe that MMs are unjust
Sentencing Guidelines and Unwarranted Disparity • Three decades of research suggests that disparities based on gender and race/ethnicity have not been eliminated • Large gender disparities • Smaller, but still significant, disparities based on race and ethnicity
Conclusion • Evidence that punitive approach does not work to improve public safety, reduce crime • Evidence that drug courts and diversion programs do work • Policymakers disillusioned with punitive policies • Attorney General Holder’s “Smart on Crime Initiative”
