  1. Introduction to Criminal Justice Chapter 1

  2. Intro to Criminal Justice • What is a crime? • What is a criminal? • Have crimes changed? • Who decides what a crime is? • Do we have more or less crimes today than 20 years ago?

  3. Intro to Criminal Justice • Crime: Conduct in violation of the criminal laws of a state, the federal government, or a local jurisdiction, for which there is no legally acceptable justification or excuse.

  4. Crime Models • Consensus Model • Conflict Model • Integrated Crime Model

  5. Consensus Model • Assumes that as people gather together to form a society, its members will informally come to a basic agreement with regard to shared norms and values. • Assumes, to a certain extent, that a diverse group of people can have similar morals.

  6. Conflict model Assumes that different segments of society, separated by social class, income, age and race, will inevitably have different norms and value systems and struggle with each other to control society. What is deemed criminal activity is determined by whichever group happens to be holding power at the time.

  7. Integrated Definition of Crime • Takes into account both consensus and conflict models. • Defines crime as any action or activity which includes: • Acts punishable by criminal law, as determined by the majority of society, or a powerful minority. • Is an offense against society as a whole. • Prosecuted by public officials. • Punishable by statutorily defined sanctions.

  8. Crime vs. Deviance • Deviance is behavior which goes against norms established by society. • Deviance is subjective. • Deviant acts are crimes only when a majority accepts that those acts should be punished. • Not all crimes are considered particularly deviant. • Criminal law defines acts the legislature has decided are so unacceptable, they must be prevented.

  9. Types of Crimes • Classified by seriousness • Six general categories • Crimes against persons (violence) • Property crimes • Public order crimes • White collar crimes • Organized crimes • High-tech crimes

  10. Violent Crimes • Crimes against persons • Four categories • Murder • Sexual Assault • Assault and Battery • Robbery

  22. Purpose of Criminal Justice System • “Criminal Justice system ‘protects individuals and the community.’” • 1967 President’s Commission on Law Enforcement and Administration of Justice • Three general goals described: • Control crime • Prevent crime • Provide and maintain justice

  23. Structure of Criminal Justice System • Federalism requires that government powers are shared by the national (federal) government and the states. • Division of powers allows states to exercise their inherent police powers. • Most criminal justice employees work for local systems.

  24. Structure of the Criminal Justice System • Three parts of the Criminal Justice System: • Law Enforcement • The Courts • Corrections

  25. Structure of Law Enforcement • Local Law Enforcement • Includes counties and cities • Chief enforcement officer in county is Sheriff • Most local officers employed by cities and towns

  26. Local Law Enforcement Duties • Investigate crimes • Prevent crimes (also known as deterrence) • Apprehend criminals • Participate in court proceedings • “Keep the peace”

  27. State Law Enforcement • Two general types of state agencies • State police • Highway patrols or state patrols • Other state agencies with specific purposes---Fire Marshal, DCI, DNR, DPS

  28. Federal Law Enforcement • Agencies with specific jurisdiction and purpose • FBI, DEA, Secret Service, Alcohol, Tobacco and Firearms

  29. Structure of the Courts • Two independent court systems • Federal system • State system (50 states and D. C.) • Both determine guilt or innocence of criminal defendants • Both have trial (lower) courts, courts of appeals, supreme court

  30. State Courts • Magistrate – hears less serious misdemeanors and small claims cases • Associate District Court Judge – hears OWI’s, misdemeanors, and civil cases • District Court Judge – hears more serious criminal cases and larger civil cases. • Court of Appeals/State Supreme Court Judges– hear appeals.

  31. Courts and Prosecution • The City Attorney can prosecute for a city (usually ordinance violation) • The County Attorney prosecutes state cases. • The United States Attorney prosecutes federal cases.

  32. Structure of Corrections • Offenders may be sentenced to: • Probation • Community-based facility or program • Jail or prison • Fine (along with other alternative above)

  33. Definitions of Sentencing Dispositions • Probation: Allows offender to return to community under supervision • Community-based program: Includes halfway houses, residential centers, home confinement, electronic monitoring • Incarceration: In local jail (short term) or prison (longer term, more serious crimes) • Fine: Financial penalty; could be imposed along with other sentence

  34. Judicial Employees • Federal 61,894 • State 164,051 2.6:1 • Local 267,972 4.3:1 • Total 493,917

  35. Number of Law Enforcement Officers • Federal 105,933 • State 156,607 1.5:1 • Local 856,396 8.1:1 • Most come from agencies with less than ten officers. Total 1,118,936

  36. Corrections Employees • Federal 34, 776 • State 463,586 13.3:1 • Local 249,888 7.1:1 Total 748,250

  37. Formal Criminal Justice Process • A series of routine operations whose success is gauged by likelihood of passing a criminal case along to “successful conclusion”

  38. Criminal Justice Process • Strives for order and discipline throughout the procedures by which the system meets the expectations of society • Does not function so smoothly as a system in reality • Actually is a balance between the formal and informal processes

  39. Informal Criminal Justice Process • Each step in process is a result of individual decisions made by those who work in the system. • Discretion: Using authority to choose between and among alternative courses of action. • The criminal justice system uses discretion to alleviate pressures.

  40. “Wedding Cake” Model of Criminal Justice • Discretion comes to bear depending on importance of case--- • Top layer---A few celebrity type cases • 2nd layer---”Higher profile” felonies • 3rd layer---”Ordinary” felonies • 4th layer---Misdemeanors

  41. Question? --- Small Groups • Should professional discretion be allowed in the criminal justice system? What are the pros and cons of discretion exercised by police, judges, prosecutors, probation officers?

  42. New Age Values in Criminal Justice • Crime control model • Most important function of criminal justice system is to punish and repress criminal conduct • Law enforcement must control criminal activity • Controlling crime is at least difficult, and probably impossible • Examples of this approach: airport searches, hidden video cameras, officers searching your valuables or back pack in subway.

  43. Values of Criminal Justice System • Due Process Model • Protect rights of accused through legal constraints on police, courts and corrections • It should be difficult to prove guilt • Assumes absolute efficiency in crime control is achieved only if power of state is absolute

  44. Which model prevails? • 1950’s, 1960’s was a “due process revolution” • Expanded rights of the accused • Severe limits on police powers • 1970’s, 1980’s was “get tough on crime” era • Slowed down the due process revolution • Restored some freedoms to police

  45. Impact of Terrorism • Terrorism became a central issue in criminal justice after 9/11/01 • New laws strengthened ability of federal law enforcement agencies to investigate and incarcerate suspects • Dramatic shift to crime control model

  46. Gang Violence • 30,000 street gangs of 800,000 members in U. S. • Gang homicides increased beginning in about 2000 • Gang violence increased partly due to illegal drug trade and use of firearms • 43 known gangs in Des Moines alone.

  47. Gang Related Crime • Previously focused on “super groups”---Bloods, Crips, Latin Kings, Gangster Disciples • Mara Salvatrucha (MS-13) attracting national attention • Roots in El Salvador in 1980’s • Up to 10,000 members in 33 states • Gang’s presence is driving up crime rates in cities like L. A. and Chicago

  48. Combating Gang Crime • Move to increase the “cost” of crime • 4 states---persons involved in gang related murders may be executed • Anti-loitering laws (Not normally a crime) • Use “immigration hammer” to detain and deport gang members
