11. Age and Crime: London Data Farrington, Piquero, and Jennings (2013)

13. High rate offenders are a small fraction of total Offenders o Chronic trajectory groups are a small fraction of the total o Wolfgang: 6% of cohort accounted for 50% of arrests o Farrington: 8% of sample accounted for 53% of convictions o Pathways to Desistance: 2%-5% of sample accounted for 50% of self-reported offending

14. Frequency of Income Generating Offending in Pathway’s Study 200+ offenses from Age 15 to 22

15. Frequency of Income Generating Offending in Pathway’s Study 200+ offenses from Age 15 to 22 Can they be identified before the fact?

17. Crime Prevention and Imprisonment: Four Important Conclusions 1.American style incapacitation is an inefficient (and unjust) method of crime control 2.There is no evidence of a specific deterrent effect

18. Crime Prevention and Imprisonment: Four Important Conclusions There is no evidence of a specific deterrent effect “…compared to non-custodial sanctions, incarceration has a null or mildly criminogenic impact on future criminal involvement. We caution that this assessment is not sufficiently firm to guide policy, with the exception that it calls into question wild claims that imprisonment has strong specific deterrent effects.”

20. Crime Prevention and Imprisonment: Four Important Conclusions 1.American style incapacitation is an inefficient (and unjust) method of crime control 2.There is no evidence of a specific deterrent effect 3.The Incremental deterrent effect of long sentences is small

21. Certainty of Punishment & Deterrence Commit Crime Apprehension P(A) Conviction P(C|A) Imprisonment P(I|A &C)

22. Risk of Apprehension & Deterrence Commit Crime Apprehension P(A) Good evidence of a deterrent effect

23. Risk of Conviction & Deterrence Commit Crime Apprehension P(A) No evidence on whether there is a deterrent effect Conviction P(C|A)

24. Risk of Imprisonment & Deterrence Commit Crime Apprehension P(A) Evidence does not support a deterrent effect Conviction P(C|A) Imprisonment P(I|A &C)

25. Crime Prevention and Imprisonment: Four Important Conclusions 1.American style incapacitation is an inefficient (and unjust) method of crime control 2.There is no evidence of a specific deterrent effect 3.The Incremental deterrent effect of long sentences is small 4.The certainty of apprehension, not the severity of the ensuing consequences, is the most effective deterrent
