Top Down approach Flashcards
what does the top down approach involve
- The creation of general typologies (types) of criminal behaviour and motivation (this was based on interviews with serial killers).
- Matching a particular type of criminal to the features of a particular crime.
focus on aspects of the criminal’s characteristics – this is why it is considered a top-down approach - helps police narrow down the range of potential subjects + prevent more crimes from occuring
how did the top down approach develop
- Used and developed in the US by the FBI
- FBI investigators interviewed 36 imprisoned serial killers - including Charles Manson and Ted Bundy
- From these interviews they gained insights into:
- What led to the offences in the first place
- What early signs there were
- What encouraged or inhibited their offences
- From these insights together with a thorough analysis of the crime details, and the intuition of experienced police officers, they created a classification system for various crimes
- In respect of murderers, the FBI distinguished between 2 types of offender
- Organised
- Disorganised
- The descriptions of these typologies allow accurate profiles to be compiled based on examination of the crime scene
what are the characteristics of organised murderers
- Above average intelligence, skilled
- Socially and sexually competent
- Living with a partner
- Mobile, usually uses own car
- Follows the crime reporting in the media
Their crimes: - Appear planned and controlled
- Include use of restraints
- Involve a weapon
- Involve the removal of evidence
what are the characteristics of disorganised murderers
- Average to below average intelligence, unskilled
- Socially and sexually incompetent
- Living alone near crime scene
- Little interest in the media coverage of the crime
Their crimes: - Spontaneous
- Little control
- Minimal use of restraints/body is often displayed in open view
- All evidence left at scene (blood, semen, fingerprints and weapon)
what is crime scene analysis
- the analysis of the crime scene that indicates the type of offender based on these typologies
- The classification can be used to determine the characteristics of the offender
- This approach means that not all crimes are suitable for profiling, such as destruction of property or murder during a robbery, as they do not reveal the personality of the offender.
what is the +ve AO3 point for the top down approach
Research Support: Shawcross
- The case of the serial killer Arthur Shawcross
- He carried out a number of murders in 1988/89
- The profile, based on 11 murders of women in New York State, was of:
- A lone male
- Aged at least 35
- With an unskilled job
- It suggested he would own a functional vehicle
- Have a police record
- And, importantly, would return to the crime scene to re-experience the pleasure of killing
- Based on this profile
- The police set-up surveillance around the body of the eleventh victim
- They caught Shawcross on a nearby bridge
He was:
- A 44 year old
- His job was to cut salads
- He owned an ex-police car
- He was on parole for earlier child murders
what are the -ve AO3 points for the top down approach
- approach has limited use
- oversimplified
- flawed methodology
expand on the -ve AO3 point: approach has limited use
- As with other profiling techniques it is limited to crimes which leave significant evidence and are multiple offences
- These crimes are rare. This also means that there are few examples of successful profiles
- When it is used, findings show that profiling rarely leads directly to the offender (Douglas, 1981)
- 15 out of 192 cases
- However, in 77% of cases it was cited as being helpful as it focused the investigation
expand on the -ve AO3 point: oversimplified
- Canter et al (2004) argued that there are no distinct subsets of characteristics such as organised and disorganised murderers
- He analysed 100 murders and found this dichotomy to be FALSE.
- Following this criticism, Holmes and Holmes (1998) reclassified murders into 5 categories:
- Disorganised ‘visionary killer’
- ‘Mission’
- ‘Hedonistic’
- ‘Lust’
- ‘Power/control killer’
- However, Canter (2004) criticised this revision further
- He reports that his above analysis showed that the features of the ‘power/control’ killings were found in over half the sample
- Therefore typical of most murders
- So not a distinct type
expand on the -ve AO3 point: flawed methodology
- Sample size for the initial interviews was small – 36
- Nor was it random
- An opportunity sample of serial killers was used
- These volunteers were known to be manipulative and so were probably unreliable sources
- The interviewers maintain that they had had prior thorough briefings on the crimes before the interviews
- Were able to detect any deception during the interview
- The interviews were not standardised
- The typologies were developed in an ‘intuitive’ and informal manner
- he classification was based on offenders who had been caught
These offenders may differ significantly from those who have remained ‘at large’
