2-6 Criminology from Theory to Practice

This chapter is the only one dedicated primarily to criminological theory, with subsequent chapters focusing on practical and legal aspects of the criminal justice system.
Topics covered in later chapters will include:
- The methods law enforcement agencies use to combat crime.
- How the court system determines guilt or innocence.
- Punishment processes for those found guilty.
Criminology's significance in the criminal justice system:
- Professor James Alan Fox from Northeastern University emphasizes the importance of engaging the public and policymakers with criminological knowledge, beyond just scholarly writing.
Evidence-Based Practices in Law Enforcement:
- Police have adopted strategies that lead to positive results in crime reduction.
- Focused Deterrence: A strategy aimed at reducing gang violence by:
  - Bringing known gang members into contact with police and social services.
  - Communicating a dual message:
    - Continuing criminal activity will result in swift, harsh punishment.
    - Ceasing criminal activity offers access to help with education, drug and alcohol treatment, and housing.
- Success of Focused Deterrence:
  - Notable outcomes include:
    - A 63% reduction in youth homicides in Boston.
    - A 35% decrease in murders involving active gang members in Cincinnati.

2-6a Criminology and the Chronic Offender

Learning Objective 9: Explain the theory of the chronic offender and its importance for the criminal justice system.

Overview:The theory of the chronic offender is critical in understanding crime patterns and informing strategies within the criminal justice system. It is based on the research from "Delinquency in a Birth Cohort" (1972) by Marvin Wolfgang, Robert Figlio, and Thorsten Sellin.

Key Findings:

This seminal study revealed that a surprisingly small subset of juvenile offenders (only 6 percent) was responsible for a significant proportion of violent crimes among nearly 10,000 young males.
- Statistics Identifying Chronic Offenders:
  - 71% of murders
  - 82% of robberies
  - 69% of aggravated assaults
  - 73% of rapes

Implications for Criminal Justice:

The concept of the chronic offender underscores repeat criminal behavior and highlights the need for targeted interventions.
Ongoing research supports the existence of this "chronic 6 percent" phenomenon, confirming its relevance in crime analysis.
Law enforcement and district attorneys have utilized these findings to develop strategies aimed at apprehending and prosecuting repeat offenders.

Strategic Responses:

Formation of specialized career criminal units by local police agencies to tackle the issue of repeat offenders effectively.
The establishment of habitual offender laws, which impose stricter sentencing guidelines for individuals with repeated offenses. These laws have gained popularity among legislators as a response to the chronic offender problem.

Conclusion

The theory of the chronic offender offers vital insights for crime reduction strategies within the criminal justice system, advocating for proactive measures directed at a small, consistent group of offenders who disproportionately contribute to crime rates. Understanding and addressing the needs and behaviors of these offenders is essential for creating effective law enforcement policies and enhancing public safety.
