Forensic Psychology ⛓️ Flashcards
What is crime?
A crime is any act or lack of acting that violates the law and results in punishment by the state.
This means that ‘crime’ is not simply behaviour that is deemed wrong but behaviour which has been identified as wrong by the law.
— It is also the case that not every violation of the law counts as a crime.
— Some breaches of contract, for example, are not punished by the state.
How does culture influence crime?
Criminal behaviour varies from country to country depending on the law in those counties.
— Eg. In the UK it is illegal for a man to have more than one wife, whereas in other countries this is not the case (Saudi Arabia).
— Eg. Laws relating to drinking alcohol.
Laws within a country change over time, criminal behaviour is not constant.
— Eg. In the UK homosexuality was illegal until 1969 and remains illegal in some countries (Egypt).
Such observations have lead to the conclusion that the definition of crime is a social construct, related to the dominant morals and values of a particular culture at a particular time.
What are the three different ways of measuring crime?
- Official statistics
- Victim surveys
- Offender surveys
What are Official Statistics and how do they measure crime?
In most countries, the government produces official crime statistics annually. In the UK, this has been produced by the Home Office since 1805 for England and Wales.
— This information is now based on any incident reported to the police or when the police observe or discover an offence.
FOR EXAMPLE: Data is given for any one year on the number of robberies, violent vs non-violent crimes, driving offences, offences experienced by children, sexual offences and so on. Home Office statistics also make historical comparisons to look at trends in crime.
In 2002, the National Crime Reporting Standard began recording any reported incident, whether or not it is reported as a crime.
Not all countries produce official statistics in the same way.
— Eg. In the USA statistics are produced by the FBI, whilst in Canada it is produced by the government agency, Statistics Canada.
— However, China and Burma are examples of countries that do not report annual statistics.
The United Nations Interregional Crime and Justice Research Institution (UNICR) monitor crime statistics around the world.
What are ‘victim surveys’ and how do they measure crime?
An alternative approach to official statistics is to ask a sample of people to identify which crimes (reported or unreported) have been committed against them over a fixed period of time.
The crime survey for England and Wales (CSEW) was stated in the UK in 1982. Since 2001 the Crime Survey has been repeated every year and now involves a sample of about 50,000 households, interviewing those aged 16 years and over in the households.
— There is also a smaller sample of 10-15 year olds who are also involved.
The sample is selected randomly by the Royal Mail’s list of addresses. This should mean that all groups of people are represented.
Each person is interviewed using a fixed set of questions which relate to general attitudes (eg. ‘In your view what are the major causes of crime today?’) or more specific (‘During the last 12 months have you or anyone else now in your household had a car, van, motorcycle etc. stolen?’).
— All data is confidential.
What are ‘offender surveys’ and how do they measure crime?
A third way to collect data about crime is to question offenders.
In England and Wales, the OJS has carried out annually between 2003 and 2006. The aim of the survey is to increase knowledge about young people and criminal behaviour.
The questions sought to produce information about the extent of offending, anti-social behaviour and drug use. The focus was on criminal behaviour and relevant contextual data.
EVALUATION: official statistics
LIMITATION - NOT ALL CRIMES REPORTED
P: A limitation of using official statistics to measure crime is that victim surveys suggest they underrepresenting the number of crimes that take place in society.
E: Walker et al. (2006) found that only 42% of crimes reported in the British Crime Surveys were reported to the police.
E: Official statistics can therefore be said to lack validity, as they are not accurate representation of levels of crime in the UK.
C: However, statistics are often accurate in representing trends in crime, meaning that whilst they may not identify levels of crime in society, they can still be useful in identifying the most prevalent crimes at any given time.
EVALUATION: victim surveys
P: A limitation of using victim surveys to measure crime is that there are methodological issues.
E: For example, victim surveys can be biased in terms of sampling, as not everyone will respond. In addition, individuals can only report five of any type of crime in year, with an estimated three million incident not being included as a result of cap (Farrell and Pease, 2007).
E: this is a problem because it limits the validity of victim surveys. By limiting the number of incidents that can be reported, some crimes may be severely underrepresented (eg. incidents of domestic violence).
L: Therefore, whilst victim surveys may be argued to be more representative than official statistics, they still do not provide an accurate picture of levels of crime in the UK.
EVALUATION: offender surveys
P: One limitation of offender surveys is that it is a self-report measure.
E: This means there is a risk that respondents may lie, or exaggerate due to social desirability bias.
E: This is a problem as it limits the validity of findings, meaning that they may not be truly representative of crime in the UK.
C: However, research has suggested that participants were very honest in their responses to the OCJS (Hales et al. 2007), suggesting that offender surveys do have some usefulness in understanding offenders and their behaviour.
What is the Top-Down Approach?
The top-down approach originates with the FBI in the US. This method was first developed as a way of trying to solve some of the most bizarre and extreme murder cases and designed to produce a profile of the most likely offender.
In contrast with the bottom-up approach, the top-down approach is regarded as a more intuitive application of a profiler’s prior knowledge.
— The profiler has a ‘feel’ for the kind of person who committed the crime.
— The bottom-up approach is regarded as more scientific and logical
What is the process of the top-down approach?
- Profiling Inputs
- Decision Process Models
- Crime Assessment
- Criminal Profile
- Crime Assessment
- Apprehension
What is meant by profiling inputs?
The data collected at this stage includes a description of the crime scene (including photographs and sketches), background information about the victim (employment, habits, relationships) and details of the crime itself (weapon, cause of death autopsy report).
All information, even if it appears trivial, should be included.
— Possible suspects should not be considered as this may bias the information collected.
What is the decision process model?
The profiler starts to make decision about the data and organises it into meaningful patterns. Some of the following issues are considered:
> MURDER TYPE
— Mass: one incident with no significant time interval
— Spree: more than one person killed over a short period of time
— Serial: more than one person killed over an extended period of time
> TIME FACTORS
— Did it take a short or long time?
— Was it at night or during the day?
> LOCATION FACTORS
— Was the crime scene (eg. kidnapping) the same as the murder scene?
What occurs at the first crime assessment?
Based on data collected, the crime is classified as organised or disorganised.
— This distinction presumes that there is a correspondence between offences and offenders.
> ORGANISED OFFENDER
+ Crime tends to be planned
+ Victim is specifically targeted
+ Body is often transported from the scene
+ Weapon is usually hidden
+ Violent fantasies may be acted out on the victim
— Such offenders are generally high in intelligence, socially and sexually competent, usually live with a partner, have a car in good working order and follow their crimes in the media.
> DISORGANISED OFFENDER
+ Tends to be an unplanned crime
+ Random selection of victim
+ Offender likely to engage very little with the victim
+ Sexual acts are performed after death on the body
— The crime scene is likely to contain many clues such as blood and semen from the offender, fingerprints and the weapon.
What is the criminal profile stage?
A profile is now constructed of the offender which includes hypotheses about their likely background, habits and beliefs of the offender.
The description is used to work out a strategy for the investigation to help catch the offender.
It is important to anticipate how this person will respond to various investigative efforts, including how the offender might be interviewed if he was caught.
