Most people in our society are law-abiding and unwilling to break laws. Law-breaking is frequently of the petty variety, so serious crime and repeat offending is often restricted to a few people who cannot or will not abide by the rules that most of us consider to be so important. Society has had to develop a complex system of mechanisms, processes and organisations to ensure that people do not break the law. If they do commit crime, society needs to be protected from their behaviour.
