behavioural and analytical tool that is intended to help investigators accurately predict and profile the characteristics of unknown criminals
the top-down approach
profilers start with a pre-established typology and work down in order to assign offenders to one of two categories based on witness accounts and evidence from the crime scene
organised offender
an offender who shows evidence of planning, targets the victim and tends to be socially and sexually competent with higher than average intelligence
disorganised offender
offender who shows little evidence of planning, leaves clues and tends to be socially and sexually incompetent with lower than average intelligence
constructing an FBI profile
data assimilation- the profiler reviews the evidence
crime scene classification- as either organised or disorganised
crime reconstruction- hypotheses in terms of sequence of events, behaviour of the victim
profile generation- hypotheses related to the likely offender
evaluation: limitation, only applies to particular crimes
top-down profiling is best suited to crime scenes that reveal important details
limited approach
evaluation: limitation, based on outdates models of personality
based on assumption that offenders have patterns of behaviour and motivations that remain consistent across situations and contexts
old-fashioned model
poor validity when it comes to identifying possible suspects or trying to predict their next move
evaluation: limitation, evidence does not support the 'disorganised offender'
