What Are the Two Most Important Factors Underlying Positive Police-Community

What are the two most important factors underlying positive police-community relationships?

A) The willingness of the public to trust and grant legitimacy granted to the police, and awareness within the police that they need to earn this through their actions
B) Police relying on knowing the offenders in the community and having civilian friends
C) The ability of police to create the appearance of conflict - that needs a police response - and the legitimacy that flows from specialist knowledge about crime
D) The extent to which police know potential offenders personally and the legitimacy granted by other police organisations
