What is a definition of crime?

What are historical issues with defining crime?
Historical issues show that what was considered a crime at one point in history may not be considered a crime according to modern standards e.g. homosexuality only being illegalised in the uk in 1967 through the sexual offences act of 1967
What are cultural issues with defining crime?
Cultural issues in crime face this same problem e.g smacking a child in one culture may be seen as acceptable or even encouraged as a form of tough love whereas this isn’t the case in the uk smacking a child so that a mark is left is now punishable by law according to the 2004 child’s protection act
What are the 3 methods of measuring crime?
-official statistics
Victim surveys
-offender surveys
What are official statistics?
Describe the number of crimes reported to and recorded by the police which have been processed and published by the home office on an annual basis
What are victims surveys?
Involve 50,000 randomly selected households to self report the number and types of crimes which have been committed against them during the past year and is published by the crime survey for England and wales annually
What are offender surveys ?
Target a randomly selected cohort of criminals who give details of the types and frequency of crimes they have committed across a set time period as recorded by the offender crime and justice survey this is particularly useful for governmental organisations as a view of the patterns and risk factors for crime at a national scale and so can be used to inform crime prevention/management statergies
Why is it a problem that official statistics are susceptible to concealing the dark figure? And what theorists demonstrated the effect of this?
75% of crime goes unreported. This may be due to a lack of standardisation of police recording policies in relation to crime as well as the victim fearing revenge/retribution or feeling untrustworthy of the police the effects of these indiscrepancies was demonstrated by farrington and dowds 1985 who found that sudden increases in incidence rates of theft could be explained by a change in police recording policies where thefts under £10 were recorded this therefore suggests that official statistics may be an inaccurate representation of crime
Why do victims surveys have an advantage over official statistics ?
The dark figure of crime is less likely to be concealed or evident due to the self report technique where individuals may feel that there are less repercussions for their actions
What methodological issues do victim surveys suffer from associated with self report techniques?
The idea of telescoping where the victim may mistakenly believe that a crime had been committed against them significantly more recent than it actually had been due to the trauma and distress associated with it therefore victim surveys maybe no more accurate than official statistics
How have offender surveys been particularly useful in informing crime prevention ?
Useful in informing crime prevention and management statergies due to showing the patterns and risk factors of offending behaviours therefore this demonstrates a real life practical application
Why is the data collected from offender surbeys may be distorted or biased as it has been collected form offenders?
These offenders may want to over exaggerate their crimes to give themselves a feeling of accomplishment and grandeur or under exaggerate their crimes to diminish responsibility this means that too much reliance can’t be placed upon the honesty and integrity of offenders in self report measures
What is the top down approach?
Uses a pre established typology and the fbi method of profile generation to assign offenders to one of two categories :organised or disorganised offenders
What 4 steps does profile generation include?
-crime scene classification
-crime reconstruction
-data assimilation
-profile generation
What are organised offenders?
Socially and sexually competent showing evidence of planning and so are unlikely to leave the body or clues at the crime scene they tend to have a specific type of victims and appear to carry out the attack in an almost surgical manner
What are disorganised offenders?
Show no evidence of planning and so frequently leave the body and clues at the crime scene e.g blood or hair their attacks appear to be random thus no specific target and more likely to occur close to their own home or operational base they are socially and sexually incompetent often living alone and being unemployed
Why is it a limitation that the top down approach can be used to explain certain crimes?
Can only be used to explain obvious,visible characteristics and so are unlikely to be effective in identifying criminals who are responsible for burglary or middle class crimes such as financial fraud this means that the top down approach may only be an effective method of offender profiling for blue collar crimes
Why is it a limitation that it’s unlikely that all offenders are able to be identified as either organised or disorganised ?
Due to thsi oversimplification of the classification system it may be more useful to study the motives that each criminal has as suggested by Keppel and Walter 1999 in thsi wat seemingly contradictory crimes can still be explained e.g. a criminal who leaves no clues at the crime scene but appears to be sexually incompetent and who carried out an impulsive attack on a stranger
What evidence is there to support the existence of an organised offender type ?
Canter et al 2004 used the statistical technique of smallest space analysis to analyse the data from 100 murders in the us with comparison of each made to 39 typical traits of both offender types the face that disorganised offenders can’t be identified as distinctly different from organised offenders suggests that this system lacks validity and breadth
What is the bottom up approach ?
Uses no pre-established typology but develops a profile as the crime scene and eyewitness testimonies are increasingly analysed the two hallmarks of the bottom up appprach are investigative psychology and geographical profiling
What is investigative psychology?
The process whereby each crime is recorded onto a database. Then the details of each new crime are matched with this database in order to develop hypotheses about the likely characteristics, social demography and motivations of the culprit therefore there is a much greater emphasis on scientific methods of investigation and statistical analysis compared to the top down approach
What is geographical profiling?
Each offender has an operational base which can be inferred through mapping the locations of previous crimes this should form a circular shape where the operational base or centre of gravity is at the centre and can also be used to predict future crimes through the analysis of a jeopardy surface
According to canter and Larkin 1993 what a re the to types of offenders in geographical profiling?
Marauders-carrying out crimes close to the centre of gravity
Commuters- carrying out crimes far away from the centre of gravity
Based on the assumption that the way and signature of offenders in carrying out their crimes are constant
