Evidnece for organised approach

Question 3

Counterpoint to weakness about it top down only beinf applicable to certain types of crimes - top down

Answer 3

It can be used for other crimes such as burglary’s
Marketa 2017 reports that using a top down approach has lead to an 85% crime rise in solved cases in the USA (wider application)

Question 4

Weaknesses - based on outdated models of personality - top down

Answer 4

Naive and informed by old fashioned modes of personality
That see behaviour as being driven by stable disposition all traits rather than external factors which are constantly changing
It’s based on static models of personality
Likely to have poor validity when it comes to identifying possible suspects and trying to predict their next move

Question 5

Evidnece doesn’t support disorganised offender - weakness - top down

Answer 5

Canter 2004
Analysed 100 murders in the USA
Examined the murders using 39 characteristics thought to be of organised and disorganised killers
Evidence was found for an organised killer but not a disorganised killer

Question 6

Weakness - classification too simple - top down

Answer 6

What happens if you have a spontaneous killer who has i high IQ a doctor, married with 2 children and the body is left at scene
There are more detailed typological models
Holmes argues there are 4 types of serial killers - visinary, mission, hedonistic and power and control

Question 7

Research support of investigative psychology

Answer 7

Canter 1990
Content analysis of 66 sexual assaults
Several characteristics were identified as commmon in most cases such as use of impersonal language
These characteristics will occur in different patterns in different individuals
Can lead to understanding of how an offenders behaviour may change over a period of time
Or if 2 or more weeks committed by the same person

Question 8

Evidence supporting geographical profiling

Answer 8

Canter 2001
Collected info from 120 murder cases involving serial killers in the USA
Location of each body disposal site in different direction from previous
Creating centre of gravity
Offenders base was located in the middle
Effect was more noticeable when the offender travelled short distances

Question 9

Strength - scientific credibility

Answer 9

More obj that top down
Less reliance on hunches or inferences
Combines geographical biological and psychological data - holistic approach

Question 10

Wider application - strength

Answer 10

Applied to wide range of offences
Can use this approach for burglary and theft as well as murders and rapes

Question 11

Weakness - mixed results for profliling

Answer 11

Caposon 1995
Surveyed 48 police forces
Found that the advice provided by the profiler was judged useful in 83% of the cases
But in only 3% did it lead to accurate identification of the offender

Question 12

Weakness - insufficient geographical info

Answer 12

Successes of GP reliant on quality of the data the police is able to provide
Recording of crimes is not always accurate
- 75% of crimes aren’t even reported to the police
Just using gp on its own may not lead to capturing the offender

Question 13

Similarities between between the top down and bottom up

Answer 13

Both used to narrow field of suspects
They both assume there is a pattern to offenders behaviour which may not always be the case
Both have captured the publics imagination
