Crime

Crime is the breach of rules or laws for which some governing authority (via mechanisms such as legal systems) can ultimately prescribe a conviction.

Causes of crime

In brief, a criminal event happens when a predisposed, motivated and resourceful offender encounters, or engineers, a conducive crime situation. The situation in turn comprises a suitable target in a favourable environment, in the absence of people who might prevent the crime and the presence of those who might promote it. This has been called the Conjunction of Criminal Opportunity

Crime categorisation

Crime can take many forms. In order to have a clear understanding of what crimes we are talking about, a clear and uniform terminology, and hence a categorisation would be required. At the moment, there does not exist a uniform and widely accepted categorisation of crimes. Rather, this categorisation is done whenever and wherever required. Some existing well-known categorisations of crime include:

Legal categorisation

The following classes of offences are used, or have been used, as legal terms of art:

• Offence against the person
• Violent offence
• Sexual offence
• Offence against property

EU categorisation

There is no uniform categorisation of crime used all over Europe. Rather, each country uses its own system to classify and record crime, but at a very generic level, the collected statistics are reported yearly to a central European database, called eurostat. The crimes in this database concern the following six categories:

• Homicide,
• Violent crime
• Robbery,
• Domestic burglary
• Vehicle theft,
• Drug trafficking

US categorisation

Crimetype statistics in the EU

The US statics, recorded by the Criminal Justice Information Services, a subdivision of the FBI, drills down to a much greater level of detail, but at the highest level of subdivision only

• Violent crime and
• Property crime

are discriminated.

UK categorisation

Crimetype statistics in England and Wales 2010-2011

The UK crime statistics, recorded in the annual report 'Crime in England and Wales', uses still another categorisation of crimes, the highest subdivision of which is:

• Property crime
• Drug offences
• Other miscellaneous offences

None of these categorisations know an EU wide base of use (at least not among parties the urban planner would be involved with). This is why we developed the categorisation of Security issues, a listing of the crimes that are of prime concern to the urban planner.

Occurence of crime

An indication of the relative size of crime types recorded in the eurostat database and their development through the years is given in the figure to the right.. In this figure, we can discern the large differences in rate of occurance between faily commonplace crimes, like vehicle theft or violence and more extreme crimes, like homocide.

As an illustration of the variability in the way and level of detail crimes are recorded in the various member states, the crime statistics of England and Wales of the year 2010-2011 are presented in the figure to the right.

Categorisation by motive

A classification that is developed for use in the urban environment that the types of crime most relevant to urban design, is based on the motivation of perpetrators:

Classification of crimetypes

The first category of criminals (thieves) is motivated by financial gain. They can be subdivided into:

• Burglars, who gain wealth by illicitly entering buildings,
• Robbers, who gain wealth by force of threat.
• Extortionists, who gain wealth by use of coercion and
• Frauds, who gain wealth by intentional deception

The second category of criminal (vandals) is motivated by amusement (such as bored youth bothering passers-by) or by compulsive behaviour (such as pyromaniacs). They can be sub divided into:

• Property vandals, who seek damage or destruction of property, and
• Person vandals, who assaults other people physically or mentally.

The third category (rioters) is motivated by impulse, often under group pressure, often in a situation with a high level of excitement or arousal. Two subtypes of rioters are:

• Protesters and
• Hooligans.

The fourth and last category is motivated by conflict in beliefs (fanatics) and tries to impose rules or beliefs upon others by use of coercion. The level of coercion can vary a great deal, ranging from mental abuse to mass killing. Subtypes of fanatics are:

• Religious fanatics, who try to impose religious beliefs or religious rules
• Ethnic fanatics, who coerce specific ethnic groups and
• Cultural fanatics, who try to impose cultural beliefs (for example about animal welfare in the fur industry, globalism or conservationism) upon others.
