Critically analyse how policing has developed from the 1970s to the present day

The essay needs or be based around the Police and the Policed, to critically analyse how policing has developed from the 1970s to the present day. The essay should also clearly address issues:
• The Police Service
• Developments in operational policing
consider how policing has changed, why policing has changed, and what issues, implications and lessons can be raised or drawn from this for a wider understanding of contemporary late-modern policing.
The essay should focus on:
– Privatisation of Policing and Security
– Active Citizenship
– Public Confidence in Policing (policing in the community)
– Mental health issues in police ignored
– Professionalisation of policing
– Diversity and Policing

Some of the areas in the essay then are:
– The origins of the modern police service (as consensual policing)
– The differing roles of police personnel (such as the role of the PCSO)
– Accountability
– Police culture
– Police legitimacy and effectiveness
– Public order policing
– Problem oriented policing

The main focus is on diversity and culture change within the police force from 1970 to the present day. Privatization of policing is a must, along with public confidence in the police and police culture. 2500 words and about 10-20 references
