Top down - offender profiling Flashcards
Def offender profiling
A tool used to solve crimes that help to accurately predict the characteristics of unknown characters by focusing on narrowing down ore existing subjects to help police build a picture of who they are looking for to make an arrest
2 types of offender profiling
Top down
Bottom up
Top down approach based on
36 interviews with sexually motivated serial killers
Stage 1 of topdown
Data assimilation - gathering crime scene evidence
Stage 2 topdown
Crime scene classification - organised of disorganised
Stage 3 topdown
Crime reconstruction hypothesis for how event occurred
Stage 4 topdown
Profile generation - hypothesis of criminal
Features of organised
Planned crime, victim is specifically targeted, body transported from scene, high intelligence
Features of disorganised
Unplanned crime, sexual acts performed after death, victim randomly selected, weapon and clues may be found at the crime scene
4 evaluation points of top down approach
Weakness - crime scene may have organised and disorganised aspects
Weakness - can only be used for certain crimes
Strength - can be accurately used for certain crimes
Weakness - subjective
Elaboration weakness - crime scenes may have organised and disorganised aspects
- general classification can’t be conducted properly
- Goodwin suggests organised/ disorganised aspects are on a continuum because too complex
- 2 categories are too simplistic
- reducing validity because most criminal don’t just fit into one category
Elaboration weakness - can only be used for certain types of crimes
- some cases there aren’t a crime scene
- harder to conduct crime reconstruction
- therefore profile generation likely to be inaccurate
- topdown approach not valid for all types of crimes
Elaboration strength - can accurately be used for certain crimes
- such as burglary that requires a crime scene
- because crime scene assimilation and classification can take place
- to produce accurate profile food application helping with police
Elaboration weakness - subjective
- there’s a high potential psychologists could get profile wrong
- police could rule of potential offenders
- misleading
- poor application
