theft and school bullying to homicide and gang problems. The projects demonstrate the wide acceptance of the method as a way to reduce significant problems. Another example of these successes are the numerous publications documenting success over the decades. Examples include Kenneth Peak and Ronald Glensor's text "Community Policing and Problem Solving: Strategies and Practices" (Prentice Hall, 1996) and Corina Sole Brito and Tracy Allan's "Problem Oriented Policing: Crime-Specific Problems, Critical Issues, Making POP Work - Volume 2" (Police Executive Research Forum, 1999). A systematic review assessed the available evidence on the effect of problem-oriented policing, with a focus on the Scanning, Analysis, Response, and Assessment model, in reducing crime and improving citizens perceptions of police. Based on 34 randomized control trials and quasi-experimental studies, they found that problem-oriented policing is effective at reducing crime and disorder, but had a limited effect on police legitimacy and fear of crime. Criticism The majority of problem-oriented policing projects fail to investigate displacement. Law enforcement is generally satisfied to achieve a crime reduction in the targeted area and may be less concerned if crime is displaced outside their jurisdiction. However assessing and understanding potential displacement effects can help ensure the effectiveness of your problem-oriented policing. However determining the extent of displacement will also assist in defending your results to critics. According to the Center for Problem-Oriented Policing, “Crime displacement is the relocation of crime from one place, time target offense, or tactic to another as a result of some prevention initiative”(Defining 2012). In addition, displacement is viewed as a negative consequence of crime prevention efforts, however, it can provide benefits. However, if a community has no trust in law enforcement, then situations like the above case studies will take place. Law enforcement and the community will have friction. As difficult as it often is for police officers to obtain "buy-in" within. It is often even more difficult to convince people outside the police department to carry out specific tasks faithfully and properly without a negative inference of its inadequacy in satisfying the expectations of the masses (Scott n.d). Increased communication with the public Under POP, the public has a much more direct hand in defining the goals of the police and influencing what issues the police will focus on. On one hand it is possible that this can cause a conflict between what is traditionally of high importance to the police, such as
