Q

41
Q

The bottom-up approach uses profiles that are ‘____-driven’

data

42
Q

How does a profile emerge using the bottom-up approach?

A

As the investigator engages in deeper and more rigorous scrutiny of the details of the offence

A

False, it is the other way around

44
Q

Which approach to offender profiling is geographical profiling a feature of?

A

The bottom-up approach

45
Q

Which type of profiling uses information about the location of linked crime scenes to make inferences?

A

Geographical profiling

46
Q

Geographical profiling uses information about the location of linked crime scenes to do what?

A

Make inferences about the likely home or operational base of an offender (crime mapping)

47
Q

Using information about the location of linked crime scenes to make inferences about the likely home or operational base of an offender is known as what?

A

Crime mapping

48
Q

Geographical profiling is based on which principle?

Spatial consistency

49
Q

The principle of spatial consistency says that people commit crimes…

A

within a limited geographical space

50
Q

True/False: Geographical profiling can be used in conjunction with psychological theory

A

True

51
Q

Geographical profiling can be used in conjunction with psychological theory such as that informed by investigative psychology to create…

hypotheses about how the offender is thinking as well as their modus operandi

52
Q

Geographical profiling assumes that serial offenders will do what with their ‘work’?

A

Restrict it to geographical areas they are familiar with

53
Q

Understanding the spatial pattern of offenders’ behaviour provides investigators with what?

A

A ‘centre of gravity’

54
Q

What is the basis of Canter’s ‘circle theory’

A

The fact that the spatial pattern of offenders’ behaviour provides investigators with a ‘centre of gravity’

55
Q

Canter’s ‘circle theory’ suggests that the pattern of offending forms…

A

a circle around the offender’s home base

56
Q

Evidence of spatial decision-making can offer the investigative team…

A

more insight into the nature of the offence

57
Q

How can evidence of spatial decision-making offer an investigative team an important insight into the nature of an offence?

A

Can give insight as to whether it was planned or opportunistic, as well as revealing other important factors about the offender

58
Q

Give 2 examples of important factors about an offender that can be revealed if spatial decision-making is recognised by the investigative team

A

Any 2 from their ‘mental maps’, mode of transport, employment status and approximate age

59
Q

The distribution of offences leads us to describe an offender in one of how many ways?

68
Q

What did Lundrigan and Canter find in their 2001 research about the location of each body disposal site in the 120 murder cases they analysed?

A

The location of each body disposal site created a ‘centre of gravity’

69
Q

Lundrigan and Canter (2001) found that the location of each body disposal site created a ‘centre of gravity’, presumably because…

A

when offenders start from their home base they may go in a different direction each time they dispose of a body

circular effect around the home base

invariably located in the centre of the pattern

short, marauders

Q

Any from its success may be reliant on the quality of data that the police can provide and relies on the accuracy of geographical data

True

The ‘dark figure of crime’

78
Q

The fact that the success of geographical profiling an investigative psychology may be reliant on the quality of data that the police can provide and an estimated 75% of crimes aren’t even reported to police in the first place calls into question the…

A

utility of the bottom-up approach

79
Q

Geographical profiling relies on the accuracy of geographical data. Even if this information is correct, critics claim that…

A

other factors are just as important in creating a profile

80
