Right realists - crime is a real problem caused by partly biological and party social influences. These causes can't be changed so they focus on deterring offenders.
Left realists - crime is caused by relative deprivation, subcultures and marginalisation. Their solution stems from reducing societal inequality.
Hernstein and Wilson - biological differences make some individuals more predisposed to crime. Eg, traits such as aggression and low impulse control signify people who are at risk of offending. Low intelligence is also a contributing factor.
Murray - crime is increasing due to the underclass being defined by their deviant behaviour.
Clarke - the decision to commit a crime is based on calculation of consequences. If perceived rewards outweigh costs, people are more likely to offend.
Lea and Young - relative deprivation leads to crime because deprived people resent others having more material goods than them, so resort to illegitimate means to achieve the materials.
Subcultures form as a collective solution to relative deprivation, may turn to crime to close the ‘deprivation gap’.
Marginalised groups lack clear goals, leading to frustration and resentment. They express this frustration through criminal acts such as violence and rioting.
A zero-tolerance policy is aimed at undesirable behaviour such as prostitution, begging and drunkenness. Police should patrol the streets and take a ‘short, sharp, shock’ approach, and carry out on stop and search on suspicious characters.
Wilson and Kelling - The broken windows theory says that visible signs of crime and disorder, like broken windows, graffiti, and vandalism, encourage more crime and disorder.
If you make it harder to commit crime (eg, by locking doors) this will reduce the rewards for the criminal and act as a deterrent.
Police departments should be answerable to the people they serve, building trust by thoroughly investigating crimes and including community members in shaping police strategies.
Increase equality of opportunity, decrease discrimination and provide jobs for everyone.
