Offender Profiling: Top-Down Approach

Offender profiling attempts to develop a set of characteristics of people that commit a specific crime. There are two main methods: a top-down and a bottom-up approach.

Purpose of offender profiling

  • The purpose of offender profiling is to help police in catching the offender.
  • The police can look at the profile and focus their resources and time on specific types of individuals.
  • The first type of offender profiling is the ‘top-down’ approach.

Top-down approach

  • The FBI first developed the top-down approach.
  • They examined and interviewed people who had committed heinous crimes such as serial killing or rape murders to develop a general description of people who commit these types of crimes.
  • The FBI interviewed 36 of these convicted individuals.
  • They were categorised into two groups: organised and disorganised.

Organised criminals

    • Intelligent
    • Socially and sexually competent
    • Did not live alone
    • Planned their attacks.

Disorganised criminals

  • On the other hand, disorganised criminals were classified as those who were
    • Not as intelligent
    • Socially and sexually incompetent
    • Lived alone
    • Were spontaneous in their attacks.

Strengths

  • Using information gathered from these interviews, FBI investigators were able to examine new crime scenes with insight into the behaviour of the individual.
  • The Netflix show Mindhunters portrays the early days of FBI criminal profiling.
Illustrative background for Limitations Illustrative background for Limitations  ?? "content

Limitations

  • A disadvantage of this approach is the fact that the crime is self-reported, which means the research lacks validity.
  • As well, the sample is completely restricted to these 36 convicted felons, this means their findings cannot be generalised to the public.

Bottom-Up Approach

Offender profiling attempts to develop a set of characteristics of those that commit a specific crime. There are two main methods: a top-down and a bottom-up approach.

  • The second type of offender profiling is the ‘bottom-up’ approach.
  • This is the type used by British investigators.
  • The approach was developed by David Canter (1994).

Geographical profiling

  • Canter developed geographical profiling which involves gathering information from the crime scene and developing a profile of the criminal from there.
  • It uses investigative psychology which applies psychological theories and research to criminal investigations.

Individual focus

  • It is described as ‘bottom-up’ as the focus is on the individual person committing the crime and the unique circumstances in which the crime took place.
  • A fictional example would the television show Criminal Minds which takes into account the circumstances of the crime to develop a profile.

Top-Down & Bottom-Up Approaches

Each type of profile looks at a different set of factors.

Bottom-up approach

  • The bottom-up approach uses geographical profiling developed by David Canter (1994).
  • There are five characteristics that should be in the profile.

Five characteristics

  1. Personal characteristics
    • E.g. personality traits.
  2. Criminal history
    • Are they likely to have committed previous crimes or related crimes?
  3. Residential location
    • Circle theory states that if you draw a circle around all of the locations of the crime scenes, the offender is likely to live in the middle.
