1. Changing Attitudes and Values โ The Enlightenment (18th century) promoted reason over fear and tradition. Philosophers like Cesare Beccaria (1764) argued that punishment should be proportionate, not extreme. Humanitarians like Howard and Fry showed prison conditions were degrading. Public opinion gradually shifted from accepting brutal punishment to demanding reform.
2. Government and Political Will โ Individual reformers could identify problems, but change required political action. Robert Peel as Home Secretary had the power to create the Metropolitan Police (1829) and reduce the death penalty offences (1823-37). The Murder Act (1965) required Parliament to vote to abolish capital punishment. Without government action, reformers' ideas remained just ideas.
3. Industrialisation and Urbanisation โ The growth of industrial cities in the 19th century made old systems impossible. Hue and cry did not work in anonymous cities of 100,000 people. The Bloody Code was not deterring crime in industrial slums. New, professional institutions (police, prisons) were needed for a new urban society.
4. Technology โ Fingerprinting (1901), DNA profiling (1986), CCTV, and computer databases transformed detection. New technology also created new crimes โ the internet made cybercrime possible, industrialisation made drug manufacturing possible at scale. Technology is both a cause of change AND a driver of new problems.
5. Key Individuals โ John Howard exposed prison conditions; Elizabeth Fry humanised female prisoners; Robert Peel created professional policing; Samuel Romilly dismantled the Bloody Code; Aneurin Bevan's welfare state reduced poverty that drove much crime. Without these individuals, change would have been slower โ but they could only act within favourable political contexts.
