✔ Most behaviours are universally identified as unacceptable - murder, rape, theft
✘ Still cult variations e.g. French crime of passion may lead to more lenient sentence for

Crime Survey for England and Wales

and analysis of crime details/scenes creating behavioural categories Favoured by FBI
(American approach)
○ Based on police exp and case studies, not psych theory
○ Suitable for extreme/unusual crimes e.g. murder/rape/ritualistic crimes
○ Behavioural Science Unit began researching family bg, personalities, crime and motives of
serial killers in 70s
○ Interviewed 36 imprisoned serial killers
○ Insight gained, analysis of crime details, with police experience, create classification
system for various crimes e.g. organised or disorganised?

collected
2. Decision process models; decisions about data & organised into patterns: Murder type
(mass, spree, serial), time factors (short/long time, night day?) and location (crime scene
same as murder scene?)
3. Crime Assessment; crime organised or disorganised.
4. Criminal Profile; Constructed included hypotheses about likely bg, habits, belief, used to
decide strategy of catching & how they will be interviewed.
5. Crime Assessment; writte
Evaluate the top-down approach - correct answer-✘ Only applies to certain crimes
✘ can measure usefulness of approach by seeing how close profile is to actual offender,
Alison, based on outdated models of personality
✘ Canter claimed evid doesn't supp disorganised offender, analysed 39 aspects of serial
killings by 100 US killers, showed no clear division between org and disorg, found org
subsets and lil evid for disor
✘ Too simplistic (Grover Godwin)
