what is crime?
an action or omission that goes against the law of the state or crown
what is deviance?
an action that is not against the law but is wrong/ against social norms
what are cultural issues in defining crime?
what is considered crime/ how its dealt with is diff between cultures

eg bigamy is illegal in uk but not other cultures
what are historical issues in defining crime?
definitions of crime change over time
eg homosexuality became legal in Britain in 1967
what is offender profiling?
the process of predicting the characteristics of an offender based on the information available
what is the top down approach?
used by the FBI
starts with the big picture and then fills in the details
how was the top down approach developed?
1970s
FBIs Behavioural Science Unit gathered data from 36 sexually motivated serial killers
problems with how the top down approach was developed?
all men- androcentric
sexually motivated- very specific type of crime
1970s- temporal validity
developed in USA- ethnocentric
36 criminals- quite a small sample size
what are the 4 main stages of constructing a profile in top down approach
1) data assimilation- profiler reviews evidence
2) crime classification- organised and disorganised
3) crime reconstruction- hypotheses formation of how crime may have taken place
4) profile generation- hypotheses related to LIKELY characteristics of the offender
organised crime
planned, self control at crime scene, few clues, target stranger, controls victim
above avg IQ, socially/sexually competent, married, angry/ depressed, follows media coverage of crimes, skilled occupation
disorganised crime
little planning, little attempt to hide evidence, minimum use of constraint random disorganised behaviour, lives alone near crime scene, sexually and socially inadequate, unemployed, abused in childhood, frightened/ confused
who produced the theory of organised/ disorganised crimes? when?
Hazelwood and Douglas
1980
evaluation of top-down typology
can only be applied to sexually motivated serial killers due to limitations of og sample
alison et al 2002 argues its based on outdated theories of personality being stable (external, situational factors have major influence)
reductionist. offenders arent either organised or not- may be features of both. may start disorganised and become more organised as they develop their modus operandi
what is the bottom up approach?
who created it and when?
the UK approach
start with details and create the bigger picture
looks for consistencies in behaviour
no initial assumptions made about offender
relies heavily on computer databases
canter 1990 (more recent)
made up of smallest space and geographical profiling
what is Canter’s most famous case?
John Duffy
