31
Q

an investigative technique for identifying the major personality and behavioural characteristics of an individual based upon an analysis of the crimes
he or she has committed
- most commonly used in cases involving violent serial crimes

54
Q

Purposes of criminal profiling

A
  • to help set traps to flush out an offender
  • to determine whether a threatening not should be taken seriously
  • to give advice on how best to interrogate a suspect
  • to tell prosecutors how to break down defendants in cross-examination
55
Q

information contained within criminal profile

A
  • personality characteristics
  • behavioural characteristics
  • demographic characteristics
    to help profilers determine the offenders:
  • sex
  • age
  • race
  • level of intelligence
  • educational history
  • hobbies
  • family background
  • criminal history
  • employment status
56
Q

history of criminal profiling

A

development of criminal profiling program at the FBI in the 1970s - first time that training was provided in how to construct criminal profiles

57
Q

investigative psychology

A
  • founder: David Canter
  • the origins of this field can be traced back to Canter’s involvement in the John Duffy (a.k.a railway rapist) rape/murder case. Drew on knowledge of human behaviour that he had gained as an academic psychologist, especially in the area of environmental psychology - spend the last 20 years developing the field of profiling into a scientific practice.
58
Q

Violent Crime Linkage Analysis System (ViCLAS)

A

was developed by the RCMP to collect and analyze information on serious crimes across Canada

  • one of the RCMPS most significant advances
  • developed in part, to prevent linkage blindness
  • an electronic booklet that police officers fill out , question supposed to capture critical information on crimes of serious nature (homicides, sexual assaults, missing persons) booklet contains more than 100 questions about the offender’s behaviour, the victim and any available forensic information
59
Q

Linkage blindness

A

An inability on the part of the police to link geographically dispersed serial crimes committed by the same offender because of the lack of information sharing among police agencies

60
Q

Deductive Criminal profiling

A

profiling the background characteristics of an unknown offender based on evidence left at the crime scene by that particular offender
- this method relies largely on logical reasoning

61
Q

Inductive criminal profiling

A

profiling the background characteristics of an unknown offender based on what we know about other solved cases
- this method is based on the premise that “if certain crimes committed by different people are similar, then the offenders must also share some common personality traits.”

62
Q

Organized disorganized model

A

a profiling model used by the FBI that assumes the crime scenes and backgrounds of serial offenders can be categorized as organized and disorganized

63
Q

organized crime scene behaviours

A

reflect a well planned and controlled crime

64
Q

disorganized behaviours

A
  • low intelligence
  • unskilled occupation
  • sexually inadequate

67
Q

validity of criminal profiling

A
  • majority of Canadian police they survived felt that profiling is a valuable investigative tool that can help to solve cases and further an investigator’s understanding of the case. however these officers also recognized the limitations of profiling, indicating that it shouldn’t be used as evidence in court for all types of crime, and that it does have the potential to seriously mislead an investigation
68
Q

geographical profiling

A

an investigative technique that uses crime scene locations to predict the most likely area where an offender resides
- basic assumption is that most serial killers do not travel far from home to commit their crimes and therefore it should be possible to make a reasonably accurate prediction about where an offender lives

69
Q

yorkshire ripper in England

A
  • one of the first cases in which geographic profiling techniques were used
  • team constructed a geographic profile , they plotted the 17 murders onto a map and calculated the centre of gravity for the points. centre of gravity fall near where the suspects was eventually found
70
Q

geographic profiling systems

A

computer system that use the mathematical models of offender spatial behaviour to make predictions about where unknown serial offenders are likely to reside

71
Q

criticisms of criminal profiling

A
  • major criticism centres on the lack of a strong theoretical base underlying the approach
  • second criticism relates to the lack of empirical support for certain profiling assumptions
  • third is that profiles may contain ambiguous information, thus leading to issues when police are asked to interpret the profile
  • a forth criticism is that professionally trained profiler may be no better than any other individual at constructing accurate profiles
72
Q

elimination lineup

A

lineup procedure for children that first asks them to pick out the person who looks most like the culprit from the photos displayed. next, children are asked whether the most similar person selected is in fact the culprit
