I agree with mobilian33. The best way of combating the accusations of racism and corruption and illegal use of force against policemen is not de-policing, and letting criminals go free. If you want to change your image then work more closely with people and have a more open door policy, so citizens can see what is going on with the police.
I think more citizens should be encouraged to take ride-alongs with police officers who are on duty. This way the citizens can get a better picture of what the police officers do as they observe them at work.
