Explain why there have been changes in the work of the police in the period from c1900 to the present day

Answer :

By the start of the 20th century, attitudes towards prisons began to change. Increasingly prisons were seen as a punishment in themselves. After 1945, the rising crime rate has led to a massive increase in the prison population. This has led to overcrowding and, at times, lack of access to education and courses.
