Comprehensive Study Notes on Crime and Criminal Justice
Core Components and Processes of Criminal Justice
The Three Core Components of the American Criminal Justice System (CJS):
Law Enforcement: Investigates legal violations and apprehends criminal suspects.
Courts: Adjudicates guilt or innocence and determines appropriate judicial sentencing.
Corrections: Manages punishment, rehabilitation, and post-conviction supervision of offenders.
The Formal Criminal Justice Process:
Functions as a multi-stage "assembly line" through which cases flow sequentially:
Initial contact
Investigation
Arrest
Custody
Charging
Grand jury / preliminary hearing
Arraignment
Bail
Plea bargaining
Trial
Sentencing
Corrections
The Informal Criminal Justice System:
Visualized using the "wedding cake" model to illustrate case processing differences.
Celebrated Cases: Represent a tiny fraction of cases that receive full formal processing and exhaustive legal scrutiny.
Low-Level Misdemeanors and Infractions: Constitute the vast majority of cases in the criminal justice system.
Informal settlement methods rely heavily on prosecutorial discretion and plea bargains rather than formal trials.
Perspectives on Criminal Justice
Crime Control Perspective:
Emphasizes harsh punishment and operational efficiency as a primary deterrent to crime.
Due Process Perspective:
Prioritizes individual constitutional protections and safeguards against state overreach.
Rehabilitation Perspective:
Views crime as an expression of social frustration and structural disadvantage.
Advocates for treating, counseling, and rehabilitating offenders.
Nonintervention / Restorative Perspective:
Seeks the least intrusive intervention methods possible.
Focuses on repairing community harm and restoring relationships.
Definitions and Conceptual Views of Crime
Consensus View:
Holds that criminal laws reflect the general agreement of society on which specific behaviors are harmful and prohibited.
Conflict View:
Posits that the law is a political tool wielded by those holding power to control the lower economic classes.
Interactionist View:
Asserts that moral entrepreneurs and social crusaders define crime based on evolving social values and moral standards.
Primary Metrics and Sources of Crime Data
Uniform Crime Report (UCR):
Compiled annually by the Federal Bureau of Investigation (FBI) from official police reports.
Categorizes offenses into two main divisions:
Part I Crimes: Violent and property crimes.
Part II Crimes: Less severe criminal offenses.
National Incident-Based Reporting System (NIBRS):
Functions as an upgraded system to the UCR.
Collects granular, detailed information on every single criminal incident reported.
National Crime Victimization Survey (NCVS):
A comprehensive phone and mail survey administered to track crime victims.
Uncovers the "dark figure of crime," which consists of criminal incidents that remain unreported to the police.
Self-Report Surveys:
Questionnaires given directly to target populations (such as juveniles) asking them to anonymously admit to illegal acts.
Crime Trajectories and Offender Patterns
Historical Crime Trajectories:
Crime rates spiked significantly from the 1960s through the late 1980s.
Overall crime metrics experienced a sustained long-term downward trend beginning in the 1990s.
Chronic Offenders:
A tiny subset of career criminals is responsible for a disproportionately massive volume of all serious violent crime.
Referenced in the landmark Wolfgang study as the "6%".
Theories of Crime Causation
Rational Choice / Classical Criminology:
Asserts that individuals logically weigh the potential costs and benefits before choosing to commit an offense.
Trait Theories:
Suggest that criminality is directly linked to abnormal biological or psychological traits.
Sociological Theories:
Attribute criminal behavior to structural environments, including poverty, social disorganization, and unequal access to conventional success.
Social Learning Theory:
Proposes that individuals learn and adopt criminal tendencies and techniques through close interactions with deviant peers.
Victimology and Victimization Theories
Victimology:
The scientific study of crime victims.
Victim Precipitation:
The extent to which a victim's active or passive behavior initiates or provokes the confrontation.
Lifestyle Theory:
Explains that crime risks escalate based on routine lifestyle choices, such as spending time in late-night environments or engaging in substance use.
Routine Activities Theory:
States that crime occurs at the specific intersection of three core elements:
A motivated offender
A suitable target
The absence of a capable guardian
