Crime prevention refers to behaviours designed to reduce the likelihood of crime by making it more difficult for a criminal or making it less worth their while
One important factor in explaining why crime occurs is the environmental design of neighbourhoods
Many modern housing developments built in the UK and USA after World War 2 were considered to be 'failing' - high rise flats with rising crime rates and poor quality of life
The courtyards gave greater surveillance opportunities for residents to see who was present in their shared space
The residents took more care for the communal areas by looking after gardens in the courtyards which suggests ownership rather than it being public
More children played in Brownsville with parent watching-building up a sense of community where Van Dyke children either stayed inside or played out unsupervised (children may be committing crime)
Disorder arises when people fear crime. When people fear crime they tend to avoid contact with others, stay inside. When minor crime happens without being challenged, this can lead to more serious crime like muggings
Following this policy, arrests for more serious crimes fell by 22% as fewer crimes were being committed on the streets
However, there could be other explanations for this reduction in crime such as the recruitment of 70,000 extra officers and the crack cocaine epidemic in the early 1990's
Foot patrol officers got to know the community - understanding who was a 'regular' or a 'stranger'
Establishing informal rules to keep order e.g. drunks could sit on steps but not lie down, begging was forbidden, drinking was kept off the main streets
Both officers and residents maintained these rules
Residents felt more confident to report disorder because they felt something would be done; breaking the rules led to arrests
The use of police vehicles was a physical and mental barrier to engaging with members of the community and having their presence felt
