I'm not sure where you've been looking in your struggles - just a simple internet search on "citizen-focused policing " throws up lots of guidance from Home Office and some case studies.
The first site I looked at is:
http://police.homeoffice.gov.uk/police-reform/ reform-programme/citizen-focus/citizen-focused -policing?version=2
This says right at the start that there are
five key areas to the citizen-focused policing programme:
� improving the experience of those who have contact with the police
� rolling out a neighbourhood policing approach across all forces by 2008
� effective community engagement � which includes consultation, marketing and communications, and public involvement
� public understanding and local accountability of policing
� organisational and cultural change to bring about increasingly responsive services where feedback from frontline staff and the public is used continuously .
This might be a starting point. The other AB respoonses will also help. Bring it to life with some examples and a mix of seriousness and humour and you'll have a good presentation
