Environmental Criminology • Traditional Criminology studies the origins of the offender’s criminal propensity. • Environmental Criminology studies the other elements of the criminal event. • EC stresses the importance of: • • • decision making by offenders and others routine activities environment imposed constraints place imposed constraints situation imposed constraints • EC assumes that offenders and victims generally use time and space in a normal (not unique or pathological) way.

9/26/2020 Environmental Criminology • Concerned with Crime not Criminals • Focus on the Presence or Absence of Opportunities to Offend • The Distribution of Crime is a Function of the Distribution of Opportunities To Offend • Has Important Implications for Crime Prevention. 2

Crime Pattern Theory • Offenders travel like everyone else • They go no farther

Crime Pattern Theory • Offenders travel like everyone else • They go no farther than they need to • They find targets in their normal travels • They do not use unusual methods of travel • They try not to travel huge distances • They often do not make special efforts to find targets

9/26/2020 VIVA Value, Inertia, Visibility, Access • Value - The offender must either value the target for what they gain or value the effect they have on it. • Inertia - The size or weight of an item can effect how suitable it is. • Visibility - How visible a target is can affect its suitability. • Access - If a target is easy to get to, this increases its suitability. 9

9/26/2020 • Offenders can sometimes be controlled by other people: these people are know as handlers. • Targets and victims can sometimes be protected by other people: those people are known as guardians. • Places are usually controlled by someone: those people are known as managers 15

9/26/2020 Situational Crime Prevention • Too much emphasis on the origins of criminal disposition and not enough emphasis on the role of opportunity • Disposition are hard to change • Societal conditions are hard to change • Opportunities are easier to manipulate • The nature of criminal opportunities influence the amount, nature, and location of crime. 17

9/26/2020 Conclusion • Opportunity has been neglected in criminology • Personal and social variables

9/26/2020 Conclusion • Opportunity has been neglected in criminology • Personal and social variables are important but difficult for police to address • Crime is a product of interactions between people and their environment • Opportunity theory enhances prevention by focusing as much on targets and guardians as on the offender • Displacement rarely becomes a problem • Crime opportunity deals with one of the most important and controllable contributing factors of crime, which is the decision to commit crime 22

9/26/2020 The 80 -20 Rule Generally, a small number of things are responsible for a large proportion of outcomes. • For example, a small number of hurricanes account for a large amount of the overall damage. • Similarly, small numbers of offenders (20%) are responsible for a large number (80%) of the crimes; or, 20% of the victims may account for 80% of the victimizations; or, 20% of places are the locations for 80% of the crimes. • The percentages vary by the particular problem, but the rule is important because crime is highly concentrated on particular people, places, and things. 23

9/26/2020 Does the 80 -20 Rule Apply? • Repeat Offenders • Repeat Targets/Victims (Hot Products) • Repeat Places or Hot Spots (Risky Facilities) • Repeat Times – crimes may also be concentrated in time (e. g. , DWI on Friday nights). 24

9/26/2020 Rational Choice Theory • Decisions to offend are constrained by time, cognitive ability

9/26/2020 Rational Choice Theory • Decisions to offend are constrained by time, cognitive ability and information • “Perceptions” of the situation and of risks and rewards is more important that actual circumstances • Decisions vary by the different stages of the offense and among different offenders • Individuals who are not normally “criminals” may choose to offend based on the perceived risks and rewards • If offenders choose to commit crimes based on a number of factors, then those factors can be altered to discourage them from choosing to offend • Crime in many circumstances is not inevitable!! 25

9/26/2020 10 Principles of Crime Opportunity 1. Opportunities play a role in causing all crime, not just common property crime. 2. Crime opportunities are highly specific. 3. Crime opportunities are concentrated in time and space. 4. Crime opportunities depend on everyday movements of activity. 5. One crime produces the opportunities for another. 27

9/26/2020 10 Principles of Crime Opportunity 6. Some products offer more tempting crime opportunities. 7. Social and technological changes produce new crime opportunities. 8. Crime can be prevented by reducing opportunities. 9. Reducing opportunities does not usually displace crime. 10. Focused opportunity reduction can produce wider declines in crime. 28
